Computer is freezing up.

Hi,

I have a Windows 7 Home premium 64 bit system. In April I was having trouble with a BSOD and we installed a new motherboard and power supply. The mother board was "ASROCK Z77 Extreme". Formatted, reinstalled Windows. Now I am having problems again. When the system is left inactive for maybe 1/2 hr, it freezes up. I have to press the power button to turn it off. The event viewer reveals that a "kernel power 41" critical event has occurred. A screen shot is enclosed.

I was advised that the CD rom had stopped working and I should disconnect it. This did not solve the problem.

I experimented with the sleep settings, set the Hard Drive to turn off in "300 minutes" while sleep setting were set to 5 minutes. The system was not happy with this, and I ended up with a BSOD. I have camera shots of various fail screens if anyone is interested.

Seeing as we rebuilt practically the entire computer in April, I would prefer not to go thru this again 4 months later. If anyone has any ideas, I would be most grateful.

Thanks... however, let me summarize the problem simply. If I leave the computer & go eat dinner or something, it will freeze up by the time I get back. As long as I put it in sleep mode every time I leave, it works just fine.

If the computer freezes up, it has to be manually shut down. Looking in the Event Log, I get the Kernel-Power error 41 (63). Yes I have googled this error and found no helpful suggestions. (I have run every diagnostic suggested, etc.) So when I try to do a System Restore, that's when the computer gives me all these weird messages such as "windows can't fix this problem' etc.

I have a feeling it was caused by one of Windows' 'Updates", as it just started happening a few days ago. Thanks Windows! I think I'll stop getting updates.
