I recently upgraded my GPU from the x850xt pe AGP listed in my profile with an x1900xtx PCI-e card. The system booted fine at first and windows detected it as a "x1900 series" card just fine cause i still had the recent catalyst installed. Then after a while the screen went blank. I kept restarting and kept having the screen shut off after a minute or two of operation. I tried to see if it happened at any consistant time, like during rendering anything or if it happened when drives were being access but i couldn't find any consistancy in it all. Then it started messing the screen up during the GRUB and windows loading windows when I rebooted it.
I immediately thought all this pointed to a PSU issue even tho my PSU is pretty good, good enough to at least run it during 2d rendering since i never even got it into 3d rendering. I removed all non-essential devices and drives and even underclocked and dropped the voltage to my CPU and RAM and it still happened. Since my PSU is modular I tried plugging it into different slots on the actual PSU body, but was met with the same results.
So since the card was a refurbished order from newegg I requested an RMA and planned on sending it back on monday. Out of curiosity (and perhaps genius) i lent the card to my friend who has an almost identical rig as mine. and it WORKED PERFECTLY FOR HIM. He played Oblivion and GR:AW for hours and had no problems he said.
the only things different about his rig are:
-cheaper Rosewill brand RAM
-different brand hdds, same interface and roughly same capacity tho
-two 80mm LED fans as opposed to my two 120mm
-prior to installing this card he had an Nvidia 6800ultra
-*HERE's THE KILLER* his PSU is the one that came with his case and has a weaker 12v than mine! I have dual 12v rails with 17A and 19A on them and he has 12A and 14A on his.
I can't figure our WHY this is happening. I mean i realize that my PSU could still be crapping out on me, so we're going to try swapping PSUs in the near future... but still..
Also I updated my BIOS to the OCWB1 and his are still the defaults. I also did the Vcore mod on mine, but didnt have any problems with it.
also, it is not heat. the card never gets hot which isnt hard to believe since it is on for so short of time b4 it blanks out.
If anyone managed to get to the end of this book of a post and has ANY suggestions or speculations please let me know as I have only so much time to return the card if i need to.
thanks
**edit** I talked to my friend and he's bring his whole rig over tomorrow. We're planning on swapping PSUs first and seeing if that fixes my problems and gives them to him. But if that doesnt work (and i have a feeling it wont) and the PSU is not the problem, I'm open to suggestions for other things to try swapping or setting or measuring.
