My dear friend,

You may think its good to call technician for it, but stop are you checked following things ?

1) See weather there is any loose connection to your system. The loose wire is most common reason of restarting computer.

2) See weather is there any power policy is set ? your PC may restart due to power policy you have set (or by any software). To see this go to start > control panel > performance and maintenance > power option (for windows).

3) Are you installed a new software or hardware after which your computer is started restarting ? if yes then uninstall it and contact software / hardware dealer.

4) Is there is unexpected shut down of your computer last time before it started restarting ? if yes it may be problem of carrepted OS.

These are most common problem that may cause your PC to restart. Most of them are easy to fix. Remember, its not wise to open your system case if you don't know about it.

Answer 3

it depends on what kind of restart youre talking about.
if the systems turns off ad back on out of the blue, there must be some hardware problem like faulty Power Supply Unit or a overheating processor (which is caused by a faulty cooling system, check the fan, it might be dead)
if you experience a frequent random Operating System restart and a System Recovery didnt help you i may suggest a full hard drive format and a fresh windows install. it could be because of corrupt registry / virus.

Answer 4

Most Likely A Computer Will Restart to Maintain updates from the system. Sometimes you will get a message if you put new software on your computer that you will have to restart in order for the software to work correctly.

Answer 5

Your problem is probably software but it may be hardware related.

If your computer stays up long enough to do the following than try the these one at a time and if the problem is fixed you are done:

• Try to narrow down the cause or situation that results in the reboot. Are you always doing the same thing when it reboots? If it a specific program, get rid of it or get it fixed.
• If you recently made hardware modifications to your computer, put it back the way it was.
• If you recently installed system updates, there may be an incompatibility between your machine and one of the updates. Try to undo, uninstall, or rollback the updates.
• Scan your computer with an updated virus scanning program.
• If using windows, in addition to the virus scan, download and scan with malwarebytes.
• If you are sufficiently knowledgeable, look at the logs on your computer to see if a problem, hardware or software, is reported that may cause the situation.
• You can try installing the latest system updates, however it is risky. If the system reboots while updating, you may lose the system entirely.

If you know what you are doing, you can use a bootable diagnostic cd or usb drive such as Hiren, UBCD (Ultimate Boot CD), etc. to run the above and other diagnostics and to try to fix your machine. Of course,you will need another reliable computer to download and burn the CD/DVD (or flash drive) since you don't want the reboot happening in the middle.

One reason for a computer to slow down and then restart, is that it may be over-heating due to dust in the fans and heat-sink. Clean it out with a can of air or vacuum.
