Top 10 Most Common Computer Problems and Solutions

1. The Computer Won’t Start

A computer that suddenly shuts off or has difficulty starting up could have a failing power supply. Check that the computer is plugged into the power point properly and, if that doesn’t work, test the power point with another working device to confirm whether or not there is adequate power.

2. The Screen is Blank

 If the computer is on but the screen is blank, there may be an issue with the connection between the computer and the screen. First, check to see if the monitor is plugged into a power point and that the connection between the monitor and computer hard drive is secure. If the problem is on a laptop, then you may need to get a professional to fix it as some of the internal wires may be worn.

3. Abnormally Functioning Operating System or Software

If the operating system or other software is either unresponsive or is acting up, then try restarting your computer and run a virus scan. To avoid having this happen, install reliable anti-virus software.

4. Windows Won’t Boot

If you are having troubles booting Windows, then you may have to reinstall it with the Windows recovery disk.

5. The Screen is Frozen

When you computer freezes, you may have no other option than to reboot and risk losing any unsaved work. Freezes can be a sign of insufficient ram, registry conflicts, corrupt or missing files, or spyware. Press and hold the power button until the computer turns off, then restart it and get to work cleaning up the system so that it doesn’t freeze again.

6. Computer is Slow

If your computer is slower than normal, you can often fix the problem simply by cleaning the hard disk of unwanted files. You can also install a firewall, anti-virus and anti-spyware tools, and schedule regular registry scans. External hard drives are great storage solutions for overtaxed CPU’s, and will help your computer run faster.

7. Strange Noises

A lot of noise coming from your computer is generally a sign of either hardware malfunction or a noisy fan. Hard drives often make noise just before they fail, so you may want to back up information just in case, and fans are very easy to replace.

8. Slow Internet

To improve your Internet browser performance, you need to clear cookies and Internet temporary files frequently. In the Windows search bar, type ‘%temp%’ and hit enter to open the temporary files folder.

9. Overheating

If a computer case lacks a sufficient cooling system, then the computer’s components may start to generate excess heat during operation. To avoid your computer burning itself out, turn it off and let it rest if it’s getting hot. Additionally, you can check the fan to make sure it’s working properly.

10. Dropped Internet Connections

Dropped Internet connections can be very frustrating. Often the problem is simple and may be caused by a bad cable or phone line, which is easy to fix. More serious problems include viruses, a bad network card or modem, or a problem with the driver

Computer Restarts when Shutting down


Based on my own experience with more than on PC and laptop, it's not always the same reason for this is error to occur, but to start troubleshooting it correctly, you should try lower gaps in testing, Specifically, it's either a Hardware problem or Software problem that causes this restarting.

Let's try the first step to reduce the gap and make sure it's not a software problem (Windows, Linux, Mac..or whatever)

Hardware Test:
If your computer was working just fine with no Sudden restart or even showing Blue Screen and then restarting
1- Go ahead make a quick boot using
Download load it, then extract it and burn it. Boot up your PC or Laptop from that CD/DVD Then Follow the pictures as below. Once the MininXp is loaded and started as a normal windows, go to start and select shutdown. If the computer Shutdown and then Restarted again by itself  then it's a Hardware Error or Bios Power Option that needs modification.









2- My suggestion now is to try to load Bios Default Settings. You double check the Power On option on your Bios setup page, by pressing any of these key For hp use F10, Dell use F2 or F12 sometimes,  Or Delete with most of the other vendors. Find Power management or Power Option Tap and Change the state power failure action to Off.  It's Better to Reset it or Restore Default Bios Settings.

Look at the following pictures of help. (These are different images for power options of different Bios versions from many Vendors)





3- The Last Hardware solution - applicable to PCs only- that worked out for me with  HP Compaq 8100 Elite CMT, was the hard reset of bios.


Disconnect all external devices first (USB Removables, Any attached Mouse or even Keyboards especially PS2 -usually causing some problems-, External AGB cards).

  • Remove AC power and the battery
  • Press and hold power button for at least 30 seconds
  • Reinstall only AC power for first startup
  • Power on - Log in
  • Next time you shut down the system, reinstall battery.
  • Reinstall keyboard and try log in to windows, if things are going good, continue adding other devices one by one till you catch the defected device.
 My problem was solved when I removed PS2 Keyboard and External AGP and  Reset Bios settings then reinstalled them back again.

The Software Solution.

 
Now we should be kind of sure it's a software issue, especially if you tried the first Hardware test using Minixp and your computer shutdown with no restart.

The first common software issue that causes this problem is the "Automatically Restart on System Failure" this option is already checked on, Remove the check mark as shown in pictures below. Right click on MyComputer >> Properties >> Advanced System settings.


On windows 8 Specifically,
Go to  Control Panel > Power Options (Change what the power buttons do) >
Change settings that are currently unavailable > *DISABLE* - Turn on fast start-up.


Also make sure the option of allowing specific device to power on the PC is turned off, this option is available on Network Card, Mouse and other devices, do that By Right clicking on My Computer and Select Manage>>Device Manager >> as listed below



 Don't tell me, it's not solved yet....Okay then, Finally you can try this:

 Hit the Start menu.....type CMD when it shows up Right Click on it and choose Run as Administrator


Copy and paste this line  SFC /SCANNOW

That should trigger a Windows System File Check....Hopefully it will do fix.

Hope that have been a helpful.
