my comp has started to switch it's self off and restart,so where do i start?

Answer 1

It WILL be overheating - 99% certainty.

(If it's does an 'emergency shutdown' - ie. it just powers down / shuts off and not an official 'reboot')

Open the case & check the CPU & power supply fans are working, if it's dusty - power OFF and blow or brush clean.

If that fails - upgrade the fan & heatsink, £12 to £15 at a PC shop for the parts.

The chances of this being a virus are slim to none.....

Answer 2

I had the same problem and after fitting a larger fan to the heat sink which protects the main chip (so I was told) also another fan on the case to bring more air in seems to have helped, perhaps your computer has over heated like mine was, but make sure your fans are all clean after of course switching of the power before opening the case.I'm sure you would do that anyway. good luck Wine Fly

Answer 3

I would start with device manager right click my computer then right click device manager look for any yellow warning signs with exclamation mark,If there is any thing wrong with your internals Hardware this should give you a clue,However I agree that it could also be Viral.Loo at Symantecs Website they have free Virus and Spy ware checker if there's anuthing on your computer that's nasty this should find it,
If you find you are redirected or the virus checking is interrupted then you definitely bug and should buy Norton from Store or ask friend to give you their Anti Virus Disk for speedy recovery
hope this helps

Answer 4

If it retains switching off with the help of itself then its probable your capacity supply(PSU) yet examine each and all the connectors on your motherboard to work out in the event that they related properly then in the event that they are and it remains switching itself off then replace the capacity supply which will probable cost you approximately £15 for a regularly happening PSU and that would desire to variety the project out, if it dosn't then its your motherboard for constructive yet which will cost you a hell of so lots extra so my suggestion is attempt this interior the order I even have reported so the main no longer costly way.

Answer 5

1.Remove the last application u have installed.
2.See BIOS setting: Power:cpu heat warning settings: set for low range,then watch for CPU heat signals.
3.check fans,blow away dust,rearrange IDE cables,keep them away from fans.
4.check all power cable connections,check RAM,make sure it is not loose
5.get free AVG virus scanner,remove all unknown entries from programme file.
6.Update Windows,security updates are available,check comp. mag. like DIGIT/pc world/CHIP they give hot fixes........

many more tips due...
If these fail there may be an impending hardware failure probably HDD, MB, RAM etc

Answer 6

The Power Supply.

If Windows detects a low voltage it will Shut down the PC.

You should also check your BIOS settings you can see the PSU voltages etc.

Answer 7

I had that problem a while back turned out to be a trojan virus. Run a scan then follow your security package instructions to get rid of it. Hope I'm wrong on this though and it's just a simple problem, good luck sorting it out.

Answer 8

If you don't know how to work on your computer, leave it alone and call a professional. Mine wouldn't even come on at all and it didn't cost me much to get it fixed. They can diagnose it at Best Buy or something. Keep your fingers crossed for the power supply.

Answer 9

1) Right-click on "My Computer"
2) Select "Properties"
3) Select the "Advanced"
4) Click on "Startup and Recovery"
5) Uncheck "Automatically reboot".

At least, you'll now be able to see the reason for the crash.

Answer 10

Check for overheating and power supply to start. Download SpeedFan to check temps and voltages.
