Windows 7: PC randomly turns off without closing windows.

I would second bej's post of electrostatic discharge being a possible culprit or a larger electrical problem. What is your computer's environment, does it sit on carpet? How many electrical components are connected on the same circuit? In any case, this sounds like an electrical problem not something occurring in Windows.

I've got my computer sitting on a piece of wood on top of the carpet (as big as the base of my case). I've got two monitors and my PC on the same board. The only thing near my computer that I can think of is a curtain which could possible brush past it when I open or close it, but it's not that close either.

40C is a lot higher than I like to see on an AMD CPU idling. Download CPUID - System & hardware benchmark, monitoring, reporting and check the core temps are lower. One thing that could be shutting off the computer is if your CPU is overheating it will throttle and then shut off and power down. You may need a new cooler heat sink and fan or new thermal paste on the CPU. Monitor the temps and report back.

I do agree that high temps could cause a shutoff and maybe I missed this, but did the OP say these temps are at idle?

Even if at idle, what is the environment and setup?
- In a desert, on a 100F day, stock cooling, no AC, dusty HSF...

More important, what are the temps under load...?

Just saying...40C temp is not a problem that would cause a shutdown.
And I love to overclock my systems just to see what i can push them to.

No he did not say they were at idle. I am just "putting it out there" as it seems to be a weird issue. Seen a lot of just shuts off stone dead due to cooling issues. 60C under load would do it with some AMD CPU's.

Hey guys, idle temp is around 35 or 36-ish. Here's a snapshot from Everest, maybe this will help?

It's no more than 25 degrees in the room at the moment, quite humid though.

Run "Auslogics" registry cleaner.(restart pc)
Just trust it - it makes an auto-back-up anyway.

Have you tried pulling one stick of memory(test) at a time to check for ram faults?

Is your pc protected by an anti-surge/brown-out power strip? (Could be a fridge/freezer or a washing machine causing surge when they kick in knocking out pc.)

I've even read reports of dodgy electric flourescent light bulbs which give off wavelengths that switch off/on tellies and 'putas!

What about under load, gaming or running Prime 95? Prime95 - CNET Download.com
This will show up any cooling issues.

I'll run Auslogics tomorrow when I get a chance. No it's not protected by anything like that, but now that you mention it I probably should invest in something...

Could you please eloborate on the testing of memory? Or maybe point me in the direction of the information I want? Cheers

I don't ever play any resource hungry games but I'll run Prime 95 tomorrow and let you know what happens, thanks for the help.
