misc: Liteon DVD drive, Encore wireless adapter.

OS: Windows 7 Pro x64

PROBLEMS:

So whenever I try to use the IE some background processes crashes... (cant remember on the top of my head)
when i use chrome, i keep getting the "oh snap" error message,
when system is idle i get random crashes of background processes and/or memory reference error.
certain windows update keeps failing to install, namely "framework 4 related updates",
windows update freezes/hangs
furmark benchmark causes nvidia drivers to fail
sometimes BSOD after mentioned problems

Attempts to fix:
several fresh installs of windows

I thought it was a memory problem so I played around with BIOS RAM clock settings AND REPLACED the sticks (newegg sent me new ones)

ran memtest86+ over night and didnt detect any problems.

Now i'm starting to think its the video card thats the problem...



any help would be appreciated.

Can you try a better power supply? It's the most important part of your system.

Do u think that is the issue? based on the rig I don't think the system should ever use more than 280

Max output on that is 216 watts on the 12volt rail. Get a new PSU. A good PSU by Antec, Corsair or Seasonic, not some pos, that I wouldn't even dare to plug in.

Definitely get rid of that doorstop impersonating a psu.

If you are on a light budget, I could suggest this psu:
CORSAIR Builder Series CX430 V2 (CMPSU-430CXV2) 430W ATX12V v2.3 80 PLUS Certified Active PFC Power Supply - $45 ($20 rebate plus $5 promo code)

I put this psu in a build for my in-laws and it is very quiet and stable (wish I could say the same for the in-laws =)

I would definitely try a quality PSU designed for current systems.

Diablotek PHD Series PHD350 350W: +3.3V@18A, +5V@25A, +12V1@18A
Antec EarthWatts Green EA-380D Green 380W: +3.3V@20A, +5V@20A, +12V1@17A, +12V2@15A

A PSU designed for current systems provides good power on the 12V rails.
