Bad stick of memory = random crashes. It could also be a capacitor heating up (bulging) and making the pc shut down.

Thread Starter 
First things first, I started up my computer this morning (12 hours or so after it happened) and it worked fine (I'm posting this from it right now).

So I think that narrows the problem to overheating, and bad memory?

Thanks for your help so far guys.

To rule out the memory, download Memtest86 and make a bootable cd with the image.

Just boot up from your Memtest86 CD, and watch for errors as the program runs. It's basically stress-testing your ram for errors.

Here's the link.

Reset your CMOS, check your BIOS settings and temperatures. Make sure, that everything is inserted correctly and you're running the latest drivers for your video card.
It's possible, that your PC is just overheating, but it's bad enough, so, checkout those temperatures and upload a screenshot or some information.

Hum, you might want to really look into your problem more I think thats a hint that something may give way down the road from pro-long use , personally If it where the memory you would be having much more difficulties booting or logging windows. (more errors on the software end)

If you still experience the problem in a short amount of time (be it the resets) and your software that you run be it windows or COD is working without crashing or errors, consider your main diagnostics for this problem, because " Computer wont boot up?" could mean a whole lot.

1. (This is the first step i would do) Remove all Power connections from the motherboard be it a battery or the ATX power cable and the 12V+ Rail, all located on the motherboard. And keep them removed for about 3 hours. Yes 3 Hrs, being because it needs time to dis-charge the capacitors both in the power supply and the main-board.

If the PC then boots from trying 1. but again starts to act up, a whole lot of diagnostics could make a list... But overall, the motherboard is getting OLD, and is probably bound for a replacement.

Noobd, here's an above picture of bad capacitors:



This is the result of a power surge and not having the machine plugged into a UPS device. This was one of my boards at work.

If you suspect it's a temperature issue then run a few hours of Orthos at priority 9. Monitor the temperatures during the stress test to see where you stand. If you don't have proper airflow in your case then you may run into overheating issues which may have resulted in the machine locking up. You can also try downloading ATITool and run the 3DView function to see how high your video card temperatures go as well.

As mentioned already, a memtest diagnostic wouldn't hurt either. I prefer to run tests 5 and 8.

Good luck

when did you start getting these problem after reformatting? after ms updates? did you install any other programs? is the hs clean and full of dust? did you run memtest on the ram?

Great support in here so far, this is great!

To me it sounds hardware related as well, just because of the symptoms.

I would go through each post, and try out each different thing, as tracking down hardware issues, it just sophisticated trial and error. I would go from the easiest to the hardest, in that order, and dont forget to check the little things (power connections and cables can be bad as well).

The only other thing that I would add, is to look for a short somewhere. This isn't hard, but it IS time consuming, because it usually involves taking the computer out of the case, and setting it up on something that isn't conductive (like cardboard).

Good luck
