I'm posting this under the PSU forum because i *think* that's what the problem is, but I'm not entirely sure. Was hoping someone else might be able to provide a little insight on a very confusing problem. Here's the story:
I've got a rig ( Core 2 Duo E6600, GT 768MB, 2GB DDR2, 850w Thermaltake PSU, Asus P5N32-E SLI Motherboard), and it was running fine until recently. I made no hardware changes or attempts at Overclocking.
So one day I go to turn it on and the video is... completely messed up -- strange artifacting everywhere, even at the post screens prior to loading into Windows (Vista Home prem). Those of you who remember the NES, remember when the games got a little screwy and you had weird video "bugs" everywhere? Yeah, looked just like that. :lol:
Tried initially doing a driver reinstall, no dice (it stopped booting into Windows, oddly). I was able to get into the OS thru CD and reformat the sucker, and it worked fine for about 2 hours, then the screwed up video returned. At this point, I presumed the GPU was shot and got a new one (this being an Radeon 4850 512mb). Uninstalled the nvidia drivers, pulled out the old card, popped in the 4850, installed the ATI drivers, good to go.
...However, here's where things get weird. Machine worked FINE. No problem, I was even able to play Empire: Total War, which is a fairly resource heavy game as a sort of testbed. Game ran fine, for several hours. I shut it off, go to bed.. get up the next day.. and..
Machine boots, goes thru its post, goes to the Windows loading screen and.. reboots. Over and over. I just can't get it to get into the OS. After a couple attempts I eventually try to get into the OS thru the CD again, and then it hangs and crashes while loading from disc. I try again, same. Finally I try to get into safe mode and i get the BSOD. I unfortunately didn't get the exact wording of the message, but it in essence told me that the machine was shutting down because the video card wasn't getting enough power. Really bizzare.
This leads me to my questions: First, obviously, is what the heck is wrong with this machine? Is the power supply bad? Is there a failure in the Mobo? Some greater issue? I'm thinking it's gotta be the PSU, but if anyone's ever seen anything similar to this (I sure haven't), I'd welcome the advice.
And the other questions.. is my initial 8800 dead? I'm thinking it is, but still, it was pricey, so I'm hoping it's might be salvagable. And the one I really can't figure out.. What happened to that 4850? Why would the machine work ok for one night and then fail the next morning? Did whatever's truely wrong with this machine (a short of some sort?) fry this 2nd card too?
Thanks for any help folks.
