Windows 7: PC restarts every one hour

19 Aug 2012   #1

Windows 7 Ultimate x64
PC restarts every one hour

My PC restarts every one hour without blue screen.

My PC System is :

Intel DG33BU_
Intel Core2Duo E6550 @ 2.33 GHz (2 CPUs)
160 GB HD
ATI Radeon HD 5450 (1 GB DDR3)

Another thing is that whenever i try to shut down it goes to shutdown mode normally but again it restarts automatically...

When i see in Event viewer it shows :
" The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. "

Event ID : 41
Task Category : 63
Level : critical

Please help me...

A similar thread was made in 2009. I'm not sure if it was resolved as the starter disappeared.

The event you posted is only a side-effect of the unexpected power down event. In other words, it's not the cause, it's just Windows noticing that something "bad" happened just then to knock out the machine without a clean shutdown.
I agree that it was a hardware issue. I've seen problems like this all over the place and they were never solved on a software level.

Repeated restarts within 1 hour
