Windows 7: Win7 Hard Freezing randomly, no BSOD

Windows 7 Pro. 64/SP-1

I'm also not sure what those temps are coming from. None of them look correct.

Could he try HWMonitor or Real Temp.

With good readings we could at least know if their is a temp problem. Always a good place to start.

Looking at the forms Tutorials at the top of every page is always a good place for information.

Alright its probably pretty much done for, at least with long distance troubleshooting. He will try a few other minor things, but at this point i'm just going to build a system from scratch.

I was able to get him to go into the bios and read that the CPU temp was 33C and system temp was like 24C so those are basically perfect, but obviously when on minimal load, not sure if thats enough of a sign to say it wont be crazy high heat once loaded.

Then he booted into windows and installed Core Temp (real temp is Intel only i believe), but it froze right as he was about to open the program. I told him to try again later and see if it can run it, otherwise just forget it and I'll have a new PC built in a month.

Thanks for your help thus far.

Win7 Prof 32bit

Wanted to continue with this since I now have the PC in my possession and was able to start some testing.

I removed the GPU and put it into the new computer since I was pretty confident it was fine being only a year old. Everything seemed to work just fine on the new PC with the old GPU and I went ahead with a Heaven benchmark to be sure it passed a minor stress test.

Back to the "broken" PC, all i did was remove that GPU and then went into a Memtest86 test (not 86+, just 86). I let it run for 3 full passes which all said fine and stopped it. It took over 3 hours to complete, is that normal? I mean is more memory and at faster clocks supposed to be slower to complete a pass? I ask because I once did the same test on an old 333MHz DDR laptop and it finished 3 passes in half the time. This is DDR2 and I forget the speed.

After the memtest86 passed, I booted to Windows and everything ran alright for the most part, just a bit slower most likely due to now being on old integrated graphics. I did not experience any freezing or crashing for many hours and then I shut it down on my own.

This leads me to think the PSU is what was causing the issues. Is it possible the majority of the PSU works fine, but when the GPU tried to pull more power upon load it had an odd voltage and caused the PC to always freeze up? I dont own a PSU tester or multimeter so if others agree the PSU is a likely problem, then I will try and see if a local shop will test it for free... assuming the testers can catch the majority of the problems.

Is there a chance the memory is still an issue and I should let it run for longer or more passes than I did to see if there are problems with the RAM? How long or many passes?

The only other thing I think could be bad at this point if not the RAM or PSU would be the motherboard socket being faulty and since the GPU was removed I guess it would be that socket? Or perhaps a memory socket, but it is fine for now upon reseating of the sticks?

Please advise on any additional tests I should perform since I feel like i should find some component to actually be bad and not just have it all work fine for me.

I don't have any advice, because I am in the same boat as you. We have 2 different machines, with the exception of I also have a NVidia GTX 750 Ti. Maybe that's a clue.
