I've tried a lot of things to try and resolve the issue. however any new options are going to cost a bit of money which I'm trying to minimize since I want to save for my Core 2 Quad system once this system is stable again.

There doesn't seem to a reason for the turn offs. I could be using Firefox and Trillian or Encoding videos or Gaming. Theres no exact reason for it that I can see.

Heres the things I've tried so far.
  • Swapped out the PSU (didn't stop to so put original back in)
  • Removed/RMA'd A8N-SLI Premium
  • Replaced with A8N-E (still doing it)
  • Ran memtest+ 1.70 for 2 hours without any errors (should I run it longer?)
  • Flipped the slots the memory is in
  • Video stability test for 200 minutes (No errors)

System specs (important ones)
AMD Athlon 64 X2 4400+ Toledo 2.2GHz Socket 939 Dual-Core Processor Model ADA4400CDBOX - Retail
A8N-E
ASUS Atlas A-55GA ATX12V 2.01 550W Power Supply - Retail
CORSAIR XMS 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 400 (PC 3200) Dual Channel Kit Desktop Memory Model TWINX2048-3200PT - Retail
BFG 7800GTX (doesn't seem to be on BFG's website anymore)

Im thinking its either the CPU or the Video Card that is dying. GPU stays at 50F at idle and 86-88F with a game running from what RivaTuner tells me. CPU cores with minimal programs running is 26-27 and 33-34 (I don't understand why the two cores would have such a seperate tempature at the same time). During gaming/encoding CPU goes up to 46-47 and 50-51 (still less then the max temperature rating for my CPU) Hopefully someone can suggest something or lend a helping hand.

P.S.
I'm in central NJ if someone has a spare Video Card or CPU that I could use to test out whats wrong a bit more (of course I'd pay for it if your willing to part with it and we find out which part is causing all the trouble)

EDIT:
Here is the last error from the Event Log
Source AmdLLD
Type Error
Event ID 11
AdjustCoreTSC()
Node[ 0 ] Core[ 0 ] Cpu[ 0 ] Affinity[ 0x1 ]
Error: HalGetBusDataByOffset() failed reading north-bridge TSC.
 
GPU temp not changing under heavy load? Sounds like the card's internal hardware could be buggered. It should change under load. Alt-tab and check while gaming.

No real advice...

updated with gaming temps. it was changing i just didnt notice it before
 
my newest error message from the system log

Type: Error
Event ID 108
The driver nv4_disp for the display device \Device\Video0 got stuck in an infinite loop. This usually indicates a problem with the device itself or with the device driver programming the hardware incorrectly. Please check with your hardware device vendor for any driver updates.
 
well i think it was the CPU. the core temps are between 0-2 degrees from each other now. much better then the 4-8 degree difference i was seeing before. no random shutdowns. now its just time to RMA my old cpu so can have a faster cpu in here. i downgraded to a 3600+ off of newegg just to test this
