Troubleshooting Computing Guide by : Sydney Lake

This is your troubleshooting guide for your computer. I hope this helps

If you have a fast processor but your computer is super slow, make sure if your computer has not been rebooted recently, make sure to reboot it before following any of the steps below.

* Close and reopen application.

* Update the application. To do this, click the Help menu and look for an option to check for Updates. If you don't find this option, another idea is to run an online search for application updates.

* One of the most common reasons for a slow computer are programs running in the background. Remove or disable any TSRs and startup programs that automatically start each time the computer boots.

- Tip: To see what programs are running in the background and how much memory and CPU they are using, open Task Manager. If you are running Windows 7 or higher, run Resmon to get a better understanding of how your computer is being used.

If the hard drive is almost full and that is causing the computer to run slower, you should :

* Unfortunately, the Disk Cleanup may not delete every file in the temp directory. Therefore, we also suggest deleting temporary files manually. To do this, open the Start menu and type %temp% in the Search field. In Windows XP and prior, click the Run option in the Start menu and enter %temp% in the Run field. Press Enter and a Temp folder should open. You can delete all files found in this folder and, if any files are in use and cannot be deleted, they can be skipped.

* As a computer runs programs, temporary files are stored on the hard drive. Deleting these temp files can help improve computer performance.

When you have a brand new computer, but your dial up internet connection is extremely slow. How can you speed up the internet, you ask? You should :

* 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.

* Most people underestimate the importance of picking a good spot for a Wi-Fi router. Even a small shift in positioning could end up being the difference between day and night.

* If you’re like most people, you probably unpacked your new router, located a reasonable outlet location, plugged it in, and simply left it on a whatever was nearby: a shelf, a desk, or even the ground. As it turns out, router height does make a difference.

* That is to say that leaving your router on the ground or behind other objects usually results in noticeably worse performance. Instead, put the router as high up as possible to extend the broadcasting range of the radio waves. This also helps clear the router of possible interferences.

What to do when you just bought the newest 3-D graphics game and you can hear the sound, but the game itself won't display. You should :

* Wait. Give the computer a few minutes to process. Sometimes a computer may appear to be frozen, but it is just slow or busy processing a complex task.

* See if the computer can respond to anything by pressing the Caps Lock key on the keyboard and watching the Caps Lock LED (light) to see if it turns on and off. If the computer can turn on and off Caps Lock, continue to the next step. If nothing happens, the computer is deadlocked, and you must reboot the computer.

* If the Caps Lock can turn on and off, Windows is still working, but another program may not be responding and causing the computer to freeze. Press Ctrl + Alt + Del to open the Windows Task Manager. If the Task Manager can open, highlight the program that is not responding and choose End Task, which should unfreeze the computer.

- Note: It could still take ten to twenty seconds for the unresponsive program to be terminated after you choose End Task.

Ok, so you recently added a new sound card, but when you started the computer you hear a few beeps right before the computer shuts down. You should :

* Try this, it might also be that your sound card has been disabled, malfunctioning, or unavailable. First, verify no conflicts or other devices are present in the Device Manager. Second, verify that the computer has a sound card and that it is enabled.

* If you have either of these on any of your sound devices, remove everything under Sound, video and game controllers and reboot the computer.

For example, your computer only stays on for 10-15 minutes before shutting off. After inspecting the back of the computer case feels extremely hot. After 3 hours you try again and it does the same thing, but this time you notice the fan isn’t making noise. What do you do? You should try these below :

* Most likely you experience a laptop overheating problem and it would be fixed by cleaning the cooling module – the heat sink and the fan.If your laptop shuts down after some time without any reason and warning, check if the cooling fan spins. Usually it makes some noise and you can hear it. If the fan works fine, then check if the heatsink is clogged. In some cases you can clean the heat sink with compressed air, just blow inside the fan openings on the laptop bottom. If the heatsink is completely clogged, then it is necessary to remove the heatsink for cleaning.

* 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.

Let's say you added a new video card, sound card, and a wireless network card to your computer 2 months ago, but you didn’t upgrade your power supply. Today, you tried to use your computer, but the computer won’t power on at all. That's a pretty sticky situation, but you could always try :

* First of all, make sure the power supply works properly. You can test it with a voltmeter.

* If the power supply is fine, your problem could be related to the memory or motherboard failure.

* If you are uncertain if the computer is turning on or not, this can be checked by locating any fans inside the computer or fans that are visible from the outside of the computer. If these fans are spinning, the computer is receiving power and this document may not apply to your issue.

* As a last resort, try removing memory modules one by one. Test your laptop with each memory module in either memory slot.

* If you have the same problem when only one memory module installed, most likely this is the motherboard failure. It’s very unlikely that both memory modules failed at the same time.

Hope this was beneficial to you!
