Top 10 tips for solving common PC problems.

9:01 AM
1: My computer is slow
The most common problem of all. A slow computer can cause many frustrations, but fortunately there is something you can do yourself before you replace it. There may be several reasons for a slow computer; however, the most common is lack of maintenance. Fragmented data, a corrupted registry, spyware and dozens of unnecessary programs running at the same time, easily eat at the speed and performance of your PC.
Tips: Keep track of your programs. Remove those of which you never use or shut them down when you've used them. Clean your registry with one of the many free or paid applications available for Windows. These two initiatives alone will easily be able to make your PC up to 30% faster. Also, run Disk Defragmenter and stop unwanted programs starting with Windows by running MSconfig.
2: My computer freezes
Also a common problem, but it is far more serious than a slow PC. In most cases it is caused by viruses, especially spyware that has been installed on your computer. It can enter via a click on a link to a fake website from an email or so on. Often the email is being sent from what looks like your bank, Paypal, Facebook or similar. Last year MYSecurityCenter registered an increase in malware infections coming from Facebook-related fraudsters among their customers.
The problem can also be caused by hardware - perhaps some memory you just installed - or recent software updates, including Windows Update.
Tips: Check the link you are clicking by holding the cursor over it to see the link's full address. Does it look suspicious? Never give out your passwords or credit card information to anyone, even if it seems like your bank requires you to verify your account. It's a clever phishing trick that hackers use to gain access to your money. Make sure your antivirus and anti-spyware software is updated. Most antivirus programs can be set to automatically to check for new updates. If you are sure that your computer is spyware free, the problem may be due to outdated hardware drivers. Check your hardware drivers for updated versions. Outdated drivers can cause your computer to stop responding and freeze.
If you suspect the problem is hardware related, you can try uninstalling any component you recently installed, or try removing or unplugging unnecessary hardware one piece at a time then booting your PC to see if the problem goes away. You can also try using Windows Restore to roll back to a previous restore point.
3: I forgot to backup my data
Unfortunately, backup is still an overlooked security task for many home users - until the day it is too late. Important documents, photos, music libraries and emails are automatically stored on your computer's hard drive, which is a mechanical and electrical device. When it breaks down (and it is when, not if) this data will disappear forever. Even if you have a warranty from the hard drive manufacturer, it does not cover your data, it only replaces the hard drive with a new one.
Tips: Find a solution that automatically makes backup to an external hard drive, server or cloud service. If you choose to back up to a hard drive, make sure that it is not placed near your computer as in case of fire it will also be destroyed. Backup should preferably be an automated process that operates independently of whether you remember it or not. Online backup solutions have the advantage that you can access your data from anywhere in the world. They are not affected by natural disasters, and most online services guarantees 100% security by providing backup to their backup.
4: I get bombarded with adware and my home page has changed
Many do not notice that they often accept a new toolbar when they download free programs such as Adobe Reader. For example Adobe Reader now offers the Google Chrome internet browser as part of its download. Whilst Adobe and Google are reputable companies, other free downloads may install toolbars or other applications that can contain malicious code that hijacks your browser and changes all the settings. So your home page for example is changed to another website that you can't then change back. At the same time, annoying pop-up messages with advertisements for products you've never asked for are constantly displayed on screen every time you try to browse the internet.
Tips: Read the conditions before downloading a new program and pay attention to what you allow. If damage is done, it can be difficult to remove the program. The best bet is to follow the instructions found when looking for information about the specific problem on Google. There are probably others who have had the same challenge and have described the solution on the internet. If you are not so technical, professional PC support may be the solution.
5: I cannot get online
Internet connection problems can be caused by many different things. The most common are network misconfigurations, hardware or software errors in the router, latency from your Internet Service Provider, incorrect IP address configuration, incorrect connection of network cables, firewall applications that block http traffic from your PC or temporary timeouts your ISP.
Tips: Check that the Wi-Fi is enabled on your computer - laptops often have a button, switch or Function key combination somewhere on your computer or keyboard. Check that the network icon on your computer is connected or if there is a yellow warning signal or it is disabled. If it is connected, call your network provider or get hold on someone with more knowledge on IT.
If Wi-Fi is disabled, you must check whether the cable is connected properly or if wifi is not on. If there is a yellow warning, you must reboot the router. If this does not work, try pressing Start in Windows XP, Vista or 7 and typing "cmd" into the search box and click enter. Then a black box pops up where you can type "ipconfig / release" then "ipconfig / renew". If the internet is not working now, call your ISP.
6: My computer turns off by itself
Typically this is due to dying power supply, bad cable connections, defective battery or overheating when the computer shuts down by itself to cool down.
Tips: Check first of all that the cables are properly connected. If the computer is very hot, check if the fan needs cleaning of dust. If it is a laptop, check whether your battery has deteriorated over time and may need to be replaced.
7: My smartphone will not synch with my PC
In order to ensure backup of your smartphone, it is important that you regularly synch your phone content with your computer. When synchronisation does not work as expected may be due to various factors, depending on the type of smartphone and PC. Sometimes it is required that all programs are closed, during synching or backup.
Tips: Close open applications, if required. Be sure to download or reject the proposed updates that pop up along the way, so synchronization can be done. Look for the icon of synchronization to appear and check if for example the latest photos on your smartphone have been transferred to the computer. Verify the user manual for your device.
8: My wireless network is unstable
An unstable wireless network is a very common problem. It can be caused by everything from radio waves that interfere with the signal to the router's location in the home or outdated network drivers.
Tips: If you suspect that it may be your cordless phone, the electric garage door opener or your radio that interferes with the wireless connection, it may be an idea to change the radio wifi settings or to move your router. The latter can also be a solution if you have trouble going online around the house or in the garden. You can also buy a wireless repeater to extend the signal. Also make sure that your network driver is always up to date. 
9: I cannot print from the web
Most of us have had the need to print tickets or documents that we ordered or downloaded from the web. If your computer's pop-up blocker is turned on, this can cause you to not be able to print. There are also PDF documents that are rights protected by passwords and therefore not printable.
Tips: Allow temporary pop-ups. You can find legitimate programs that can break the code in a protected PDF document, but they are usually only legal to use if you or your workplace have the copyright to the document.
10: My computer makes strange noises
If your computer suddenly starts to buzz or vibrate, it can be due to a hardware failure. High, whining noises may indicate problems with the electrical components, while buzzing noises are often caused by lack of ventilation.
Tip: Clean the filter and fan for dust and make sure that all air inlets are free. If you have a laptop, you can try to uninstall and reinstall your sound drivers. If it is a desktop, it may be that the sound card needs replacement.

How to solve the 10 most common tech support problems yourself.

9:05 PM
Whether you’re dealing with your dad’s decade-old computer or your own custom-built gaming rig, troubleshooting PC problems is a part of everyday life. Before you make that $50 support call, though, try your hand at homebrew tech support. We spoke to some of the best support reps in the business about the most common problems they fix—and how you can do it yourself.

Try this first

I know it sounds like a no-brainer, but before you do anything else, restart your computer. 
Regularly checking for operating system updates is important, because forgetting to do so could significantly impair your PC’s performance.
While you’re at it, make sure that your operating system is fully updated by running Windows Update. Neglecting updates could deprive you of important bug and performance fixes.
If you’re having problems with a peripheral, try switching it on and off. If that doesn’t work, try disconnecting and reconnecting the device. As a last resort, download the latest drivers and perform a full reinstall.

My computer is too slow

The first step to fixing a slow computer is to verify that your machine is the actual source of the problem. Videos that seem to buffer forever, and websites that take ages to load, may not be your computer’s fault.  See “Downloads are taking forever” below for instructions on how to use Speedtest.net to diagnose a slow connection.
If the problem is your PC, check whether you have plenty of free space on the hard drive holding your operating system. Windows needs room to create files while your system is running. If your hard drive is maxed out, performance suffers. Now is the perfect time to clear some space.
If your computer’s operating system resides on an overstuffed C: drive, clearing out some space could boost OS performance.
Microsoft’s System Configuration tool is your next-best bet for tackling slow performance. Many applications launch automatically when your machine boots up, which can stretch out boot time—especially on older, slower PCs. Make a habit of trimming the startup items. Open the tool by pressing Windows-R, typing msconfig, and pressing the Enter key.
Checking the Startup Item and Manufacturer columns is the best way to figure out which potential performance-killers you can safely disable. Avoid messing with any of the services and programs that have Microsoft Corporation listed as the manufacturer. Items such as AdobeAAMUpdater, Google Update, Pando Media Booster, Spotify, and Steam Client Bootstrapper are all fair game. Regardless, err on the side of caution: If you’re not sure what the program or service does, don’t disable it.
Windows’ System Configuration Tool lets you disable programs and services that automatically start when you boot your computer.
Once you’ve made all your changes, click OK and restart the computer. It should boot up quicker and feel noticeably faster.

Downloads are taking forever

Speedtest.net is your best friend when you're having connectivity problems. Run a speed test to see what your download and upload speeds are—ideally they should be at least 50 percent of your Internet service provider’s advertised speeds, with a ping under 100 milliseconds.
If the speeds seem solid, make sure that you aren’t inadvertently downloading or uploading anything. Many torrent downloading programs run in the background and minimize into the system tray instead of the taskbar.
A good speed test should give you an accurate assessment of your ping, download speed, and upload speed.
Check your network hardware. Updates for network cards aren’t all that common, but if your card’s manufacturer offers a newer driver, download it. Resetting your router and modem can help with connection problems, too. Most routers and modems have reset buttons, but pulling the power cable for a second or two can do the same thing. Don’t cut the power for much longer, or the hardware may reset itself to factory defaults.
Still having problems? Call your ISP, which can tell you whether the problem is on your end. As a last-ditch measure, the ISP could reset the master connection to your home.

My machine keeps restarting

Hardware problems are hard to diagnose and solve. First, confirm that you aren’t just getting the latest wave of Windows updates, which can automatically restart your computer during installation. Then work on updating all of your critical system drivers. Your graphics card, motherboard, and network card drivers are crucial.
“Sometimes it can be viruses, sometimes it can be adware, sometimes it can be overheating, and sometimes it can be something as simple as making sure your video card is updated,” Geek Squad’s Meister says.
Is your computer making weird noises? If you’re lucky all you’ll need to do is give the machine a thorough cleaning. Modern computers have safeguards that shut down the system if a component is overheating, which can be the cause of frequent restarts when you’re running resource-intensive programs or video games.

Pop-up ads are appearing on my desktop

If you’re not running your Web browser and are still getting pop-up ads on your desktop, you’ve most likely installed adware—a program that displays unwanted ads. Although benevolent adware exists, most of the time adware is up to no good. Getting rid of it isn't easy. “There’s a ton of little system-utility tools out there that promise to clean up everything, with names like PC Speed-up, PC Speed Pro, PC Speedifier,” Geek Squad’s Meister says. “A lot of times those programs are not going to do much. Some programs will work, others are snake oil.”
Avoid downloading programs that offer to speed up your PC or clean up your registry. Instead, use a trustworthy adware scanner like the free version of Malwarebytes' Anti-Malware tool.
Running a full scan with credible antivirus software is your first step. If that program doesn’t find and remove the adware, turn to Malwarebytes Anti-Malware Free, a great utility for removing all types of malware. Just make sure to disable your standard antivirus software before running it.
“Multiple antivirus programs working at the same time will often result in problems,” Falcon Northwest’s Petrie says. “You only want one active, real-time antivirus scanner installed, but it doesn’t hurt to run an additional ‘on demand’ virus or malware scanner.”
Searching online for the name of the advertised product can sometimes yield solutions from fellow victims. If all else fails, there’s always the nuclear option: a complete system reinstall. It might take a long time, but it’s the only surefire way to remove adware or spyware. Remember to back up all your personal files.

Google doesn’t look right

Browser hijackers are a particularly nasty breed of malware. Such programs take over your Web browser and can stealthily redirect your Google searches and other queries to fake pages meant to steal your personal information or to further infect your system.
Running a real-time antivirus utility is the best way to stay safe. If your browser has already been hijacked, uninstall the browser and use your antivirus program in conjunction with Malwarebytes to remove the intruder.

My Wi-Fi keeps disconnecting

Spotty wireless connections can be a puzzler. Is it your computer? Your router? Your ISP? Try a few things before calling your Internet service provider.
Windows Network Diagnostics may not always solve your problem, but it will usually point you in the right direction.
Confirm that your computer is within range of your wireless router. Weak signals mean weak connections. Next, make sure your PC’s wireless card has the latest drivers. Try letting Windows troubleshoot for you by right-clicking the Wi-Fi icon in the taskbar and selecting Troubleshoot problems.

I keep seeing ‘There is a problem with this website’s security certificate’

Sometimes the biggest problems have the easiest fixes. According to support technicians, the lion’s share of issues are due to an incorrect system clock.
The problem is probably with your computer.
Website security certificates sync up with your computer’s clock. Old computers in particular run the risk of having a dead CMOS battery—the watch battery in your computer that keeps its system clock ticking. Click the clock in the system tray and selectChange date and time settings to correct any issues.

My printer won’t print

Let’s assume that your printer’s drivers are up-to-date, and that it has enough paper and ink or toner to print. Try turning the printer off and on. Unplug the printer and plug it back in. Check your printer’s print queue by looking for the printer icon in the system tray and double-clicking it. The print queue shows you the status of each job as well as the general status of your printer.
The print queue is your best bet for troubleshooting printer problems—just make sure that ‘Use Printer Offline’ isn’t selected.
Ensure that ‘Use Printer Offline’ isn’t checked. Sometimes, printing while your printer is turned off can cause Windows to set your printer to work offline, and that can stall jobs sent later.

I can’t open email attachments

If you have ever encountered an attachment that you couldn’t open, it was probably because you didn’t have the software necessary to view the file.
If you don’t have Adobe Reader or another PDF-compatible program, you won’t be able to open that TPS report.
The usual suspect is the .pdf file, for which you can download a free PDF reader. If your problem involves a different file format, a quick search on the attachment’s file extension (the three letters after the period in the filename) should tell you what type of program you need. If the attachment lacks a file extension (which might happen if it was renamed), adding it back should set things right.

My favorite program isn’t working on my new PC

Before you call tech support, make sure that the software you’re trying to run is compatible with your operating system. Older software might not function on Windows 8, and an app created for Mac OS X definitely won’t run on your Windows PC. A 32-bit program might run on your 64-bit operating system, but it doesn’t work the other way around.
Not all file types work on Windows. For example, files that have the .app extension run exclusively on Mac OS X.
If an online game balks, you might be missing the required plug-ins—Java and Flash are the usual culprits. Most browsers will alert you to install these items if necessary.

When to throw in the towel

Falcon Northwest’s Petrie recommends connecting with tech support for “any problems that you aren’t comfortable addressing personally.” When in doubt, it’s better to steer clear of voiding a warranty or potentially damaging your system. “Being aware of your own skill set and limitations is important,” says Petrie, because “it’s often easy to make matters worse.” If you think the problem is too complicated, call up a more knowledgeable friend, or bite the bullet and work with a professional tech support service.
