Hi, sorry this is a bit long-winded, but I desperately need some help!
I have a 9400/E1705 with a 7900gtx (Vista 32-bit). I thought I had fried the memory on it after using it with a stock 90W adapter and T7600 and getting BSODs with Memory Parity Error when playing games or even running the Vista performance metre thing. After trying everything (apart from a re-format), I bought a new card.
I installed this with the NBF 169.04M6 driver (which I was also using with the old card), and all was fine for a while until the lower half of the screen suddenly started flickering when using a game editor (as did the previous card before getting a BSOD) . Rebooted, and the screen had dashes, lines, etc across it and was unable to boot into Vista unless in safe mode. Tried uninstalling and reinstalling drivers, then reformatted and reinstalled Windows, but couldn't complete installation since the display didn't respond, as before, when entering Windows. Since the same dashes, lines and commas remained during intial boot-up I'm assuming that the card is dead?
Have since put the old card back in, which at least powered the display and was fine for everyday stuff. Installed the same NBF driver, and when Vista loaded and ran the performance metre it got through it fine (it used to crash previously). I therefore tried running the game editor (enough to crash it previously as well) and ran Far Cry, with fine results for a few days. Today, on reaching one slightly-more light-intensive indoor patch in FC, the lower half of the screen went berserk again flickering, as it used to do. Ran FC a bit more after a reboot and all was fine, though I switched to lo-res for the indoor bit. Haven't pushed it otherwise since, but am not sure what to make of this. Is it the driver or is the memory truly dead? Am also puzzled by the "death" of the second card (which I still have).
Any help would be greatly appreciated. Have wasted so much time with these stupid cards that I want to chuck the laptop out and build a PC!
