Computer reboots for no reason

by gharbell / July 27, 2009 9:09 AM PDT

My computer fequently will just shut down and reboot for no reason. I don't get any error message on reboot. It happens when different applications are running. Sometime just the application will suddenly close down, and sometimes the whole system will just shut down and reboot. It can happen within 5 minutes of starting, or after several hours when the CPU has heated up. I've updated all the drivers. Can anyone give me any suggestions?

Used Compressed Air To Clean It Out Lately?
by Grif Thomas Forum moderator / July 27, 2009 9:17 AM PDT

If not, buy a can of compressed air at your computer store, take off the cover from the computer, then blow the dust from around the processor, the heat sink, the power supply and all fans and vents.

Hope this helps.

I think your computer is infected by a virus, try to scan your computer with anti-virus software.

Possible fan is faltering
by Willy / August 1, 2009 9:18 AM PDT

It maybe a failing fan as its intermittent in operation. This means all *FANS* should be checked, especially the PSU one. The other posters also touched on others areas to check, as they all should be reviewed/verified. If a fan problem, replace. However found bad in the PSU, replace the PSU as it maybe compromised already and going downhill due to heat stress.
