Locks up once and then is fine

[bradbehrens]

My system is exhibiting very odd behaviour. I have noticed that when I have it running for 20-30 minutes it is fine but then suddenly freezes and NOTHING is responsive. I have to hit the reset button. The everyhting is fine even when put to sleep. But the next time I turn the computer off for a while it returns to this behavior. I have already replaced the motherboard once becuase the original one they shipped locked up 50% of the time on initial boot up (so it definately was a different problem that I determined was a bad motherboard).

I am running Windows 7 clean install but have had a lot of problems with the ASUS software and drivers. The ATI Catalyst Control Center will not install and will not stop trying to install either. Not real happy with ASUS and Windows 7 right now. Internet Explorer crashes constantly but M$ says that it is an add-on and running IE without add-ons seems to bear this out. I have not yet figured out which add on is the culprit but this has not stopped the computer freeze problem.

Any ideas if it might be software, hardware or drivers or something else?

I had a similar problem once with a different mobo brand. My issue was solved with a BIOS update.

Hmmm...

Interesting.

I updated my mobo BIOS once already because I had seen a problem with the original mobo (before I RMA'd it due to a boot issue) that a a specific BIOS update resolved and so this time just updated the BIOS because it resolved that one known problem on my mobo already. However, ASUS has come out with another BIOS update in the last month so I will try it and let you know if it solves my problem.

Losing confidence in ASUS M4A79T Deluxe and they have had BIOS updates at least once a month. Is that normal?!?

Updated the BIOS to the very latest and this problem persists. I have never seen anything like it.

Any other suggestions from anyone?!?
