Windows 7: Computer Crash

Computer Crash

Every once and a while the screen will go black, and then the sound will cut out which is then followed by nothing being responsive. The caps and num lock dont register on the keyboard so i dont suspect that the video is going dead. Also, the computer wont work correctly until the computer hard resets. I just replaced the ram because it was being questionable. the only other thing i can think of it being is the psu or mobo.

this was something that only happened once a year, then twice and now quite regularly, which only adds to my thoughts of it being the psu. has anyone had any sort of experience with this? im really at a loss of where to look next, and any help is GREATLY appreciated.

Perform clean boot to see if the problem persist. If on that mode, you dont have any issue so it could be software or drivers problems.
But if the problem still remain, I'll suspect the hardware such as PSU and motherboard. You may test to use another PSU.

Have you checked your CPU temps?

Use the free Real Temp, check temps at idle and under load.

Open the case, if there is a lot of dust, clean it out.

Then run these testing utilities:
RAM - Test with Memtest86+
CPU - Stress Test with Prime95
Video Card - Stress Test with Furmark

@wish I dont suspect it to be windows, because it has happened in linux as well. also, it happens intermittently. however i updated the bios (never did it before now) in hopes that it could be the cause.

@David Ive sent my ram into gskill and they sent me some new ones so i dont suspect it to be the issue. Also not a lot of dust as a i clean it every couple months. The cpu is running in upper 30s idle and low 40s for load. ill do those tests you mentioned and report back.

thanks guys!

Sorry to say but, new RAM can fail.
Memtest86+ can indicate if the settings need adjustments.

You are trying to narrow down the hardware possibilities, this is best done by running the above tests.

OK here's the update. Still trying to find a psu to use to test with, however im not empty handed.

Ran Prime 95 for 4 hours for small ffts without error. I also ran the furmark and it topped out at 74c but hovered between 72-73c. No artifacts and still running.

Starting an overnight session of memtest 86, and im not sure if i was running the 32 or 64 version of prime95 so i might run that one again.

Thanks for the update.

Let us know the results of the tests.

Ran 7 passes of memtest86+, no errors.

any specific test on prime 95 i need to run?

Edit:

Also wondering, could there be a ram setting in the bios that needs tweaking? Im just wondering if stability is an issue.

Also, this may or may not be a new symptom. The last time the computer crashed, the screen went a solid color and froze there. Not sure if that indicates the video for sure or what. Thanks!

How much RAM you have installed?
With some information we can see if any adjusting is required.

Download CPUZ and post a snip of the CPU, Mainboard, Memory, and SPD tabs.

For posting the information , enter 'Snipping tool' in the Start button > Search box, hit enter. Select the area you want to post and save to a convenient place.

Go to your BIOS and tell us what the CPU, RAM and North Bridge (NB) voltages are.
