Windows 7: BSOD

Hey peeps, i've been having computer problems the last 3 months. The problem i get is random freezing, no BSOD. I replaced most of my parts 2-3 times, except Vid card and PSU.

My buddy took my computer (he's a tech) and said video card is fine, he ran memtest for 1 day (no errors). He prim95'ed my cpu for 12 hours, temps were fine. He benched marked my video card and it came out above average.

I took it home and I started up SC2 and boom, computer freezes. NO BSOD. Just screen gets stuck. I restart, decide to run youtube and freezes again. I noticed the one thing he didn't check was my on board sound card. When i run sound, it crashes my computer (so i assumed atleast).

I did some research and found this post:

GTX 470 Freezing

Very similar to what i was experiencing.

I noticed this post from the above post:

I did do the above, but i didn't uninstall the drivers, i just disabled the audio. My computer for the first time stabalized for about 4 days. but..

Today I got my first BSOD, quite a few in a row actually. Was wondering if anyone can help me figure this out.

Thank you.

If you need more info, please let me know. Thanks in advance for any help.

One dump blames nvlddmkm.sys, part of your nvidia driver

Causes:bad RAM/PSU, incorrect RAM timings/voltages, bad Graphics card, overheating

It could be overheating in your case

Uninstall the Nvidia drivers then use driver sweeper to remove the leftover Nvidia files
Guru3D - Driver Sweeper

Then reinstall the Nvidia drivers:

This was likely caused by the following module: nvlddmkm.sys
Bugcheck code: 0x116 (0xFFFFFA80069C03A0, 0xFFFFF88004948D0C, 0xFFFFFFFFC00000B5, 0xA)
Error: VIDEO_TDR_ERROR

Thanks for the reply. I'm in the process of rmaing my video card.
