Win7 PC locking up

[2Drunk2Funk]

When I play a game and I guess, stress the system more, it completely locks up. This can happen 2 hours in, or 5 minutes in, sometimes fine for days... recently however, it seems to be occurring constantly

I have cleaned the inside (it was dusty!) and checked the fans are operating on the CPU and GFX, they look fine and no apparent over heating problem.

I installed SpeedFan to see if I can see the temperates in Windows, rather than through the bios. Image below is a snapshot under browsing conditions with PC up and running for an hour.

CPU/GFX look ok, I have no idea what Aux is but it looks to be a problem??

Any ideas, and other things I can try?

Enabled logging with speed fan and while playing game the GFX was beeping as I set it to if the temp went over 58, it hit 60, is that too high?

Card in sig, I took it out, cleaned it as best could, fan works etc but getting that hot with the side off.
Never used to have a problem when on XP, not sure if that is it but not crashed today having it with no side on.

Been happily working for couple years though so rather strange.

I am having a similar problem with my vista pc.

It could be a problem with your system voltages.

My pc got gradually worse over time freezing up very often. I had recently installed a lot of new hardware over this period and thought it could be one of those pieces causing the freezing. (3 case fans, wireless card, 3rd HDD etc) So I tried unplugging one by one which didnt help then it hit me. My voltages are set to auto in the bios, maybe the board isnt setting the voltages right. So I have manually set the voltages, slightly on the high side but not dangerous, and it SEEMS to be working ok now but I havent used my pc enough since to say whether it has been fixed or not.

So the first thing you want to do is check voltages and up them slightly if you feel comfortable. Im not an experienced overclocker so I cant recommend to voltages to set but im sure people on this forum could or just monitor temps very carefully.

If this does not work you will want to find a Working State of your pc. This means unplugging everything that you do not require. I.E. only having cpu, 1stick ram, OS HDD gfx etc.

If it still locks up, swap the ram stick, try new gfx (if available) untill you have a working state then add the other components one by one untill it starts locking up again. Then you know that part is bad.

Try updating all of the drivers, (gfx, mobo) update windows. Re install windows.

Thats all I can think of. Hopefully someone else knows how to fix this problem for us, Good luck
