Answer 1

Check to make sure the air vents on your PC are free of dust. It could be over heating or your power supply could be checking out.

Answer 2

There could be 2 reasons:

Of Software: Your PC is infected with a virus, there are a couple of virus which do this. Maybe your AV is not upto date with the latest virus definitions database. If this is the case then do following:
Update your AV by going to www.mcafee.com and downloading their latest virus definition file, or by selecting AV update in your MCAfee console.
Then visit update.microsoft.com and it will tell you the missing patches, install them. Sometimes after patch installations the virus are de activated.

Of hardware: If this is not a software problem then this is a Microprocessor or the heat sink problem. Either your microprocessor has developed faults so its rebooting the system, or the heat sink attached on top of the microprocessor is faulty, which is causing overheating. In both cases you would have to consult your PC vendor and whatever part is faulty needs to be replaced.

The system rarely reboots on hardware problem with other components like motherboard,RAM etc... but it sure gives this problem if the microprocessor assembly develops fault. Hence the pinpoint on microprocessor

Hope this helps you out.

Answer 3

If you can get into Windows, try the following:
Start button, then Settings
Go to the Control Panel
Click on the system icon
Click the advanced tab
Click on Startup and Recovery
Uncheck the box about 2/3 of the way down that says "Automatically Restart"

This will NOT resolve whatever is causing the restarts, but it may allow your computer to display the error and other information needed to fix the problem, rather than just restarting.

Good luck

Answer 4

If there is a pop up message saying your computer is going to reboot in "X" seconds then your computer has the Sasser Worm. To remove it you can go to Microsoft.com and download the sasser worm removal tool.

Mcafee, Norton virus scanners do pick up these viruses but you have to update your them (its recommended to use only one since having many scanners can cause conflicts with each other and slow down your computer tremendously). However, your subscription may be over and you'll be asked to buy a new subscription.

Answer 5

Open'er up and see if there is alot of dust inside, if so go get a can of Air and blow it out.
It sounds like it is overheating but it might be a virus
go here
http://dsvs.org
and download
LavaSoft Ad-Aware
and
Microsoft Antispyware
run scans
on that site is a online scan called
Trend Micro
you could try running that although it takes awhile usually.
Really more info is needed like; how long this has been happening, what OS, etc....

Answer 6

Sounds more like a hardware issue than a software occurence. Try and start it in safe mode if it does it again in safe mode it is likely a problem with your PC and needs to be repaired.

Answer 7

The restart is a common symptom for both viruses and hardware issues. If you recently installed or updated something on your system, try uninstalling it and work back from there.

Answer 8

It could be a problem with one of your registry keys. Get a program that fixes registry problems. If it doesn't clear it up, your best bet is to reload it back to factory settings.

Answer 9

it could be a virus or worse....go to geeks to go.com and sign up....i used them when i caught the smitfraud virus and they worked with me to get rid of it. saved me from going to the computer shop. The sign-up is free and the services and help is free too...Godd Luck

Answer 10

try booting in safe mode and see... Mccafee is pretty good at slaying down viruses..
