Help Diagnose Prob with Phenom II X3 720 PC

So this is my parents PC.



Troubles its having it randomly locks up, even at the Bios splash screen at times and it happens a lot during Windows 7's loading screen. Things I have tried are a 6 hour memtest which came up with no errors, windows update and cccleaner. I've tried safe mode as well but even then sometimes booting up it will lock up. I have switched the PSU, I have reset bios to optimized defaults. I really don't know what to do anymore, I'm not sure if its high temperatures causing the problems but I do think they are too high. Sometimes after shutting the PC off it won't turn back on unless pulling the the power from the PSU and hitting the power button again. This is leading me to believe its something with hardware and not software.

Also the case its in is horrendous as it has no intakes nor an exhaust...lol

Anyway any input or advice would be appreciated. Mods, could you please move this over to AMD General forums or any other place you seem better fit for this type of question, thanks!

It's possible that your CMOS battery is dying. I had a similar problem with random lockups on a PC my brother and I built. It was 12 hrs Prime95 stable, but would randomly lock up and shut down on its own. Only pulling the power supply plug and leaving it there for a while allowed me to reboot the PC.

Once we replaced the CMOS battery on the motherboard, all the problems went away.

Yup. It was incredibly frustrating trying to diagnose the problem. We knew the CPU was more than stable after our stress tests. We set everything back to stock, switched out CPUs, RAM, PSUs, GPUs, everything.

What finally gave it away was that the system clock time would go into hyper speed. Minutes would pass by in just seconds, which is when we realized that it was probably the CMOS battery at the end of its life. Swapped that sucker out for one we had laying around and bam! Problem solved.

Hopefully that will also resolve your parents' PC issues.
