Code 43 started with GTS 250 now GTX 460
Hello,
This machine was *originally* a home built XP budget gaming machine from a couple years ago. The important specs are as follows (don't laugh too hard):
Mobo:ASRock 4 Core-Duo SATA
CPU: Intel E5200 Dual Core 2.5ghz (I have used it at 2.7 before)
RAM: 2 Gigs GDDR2
PSU: Is a 550 watt
GPU: Formerly GTS 250, now GTX 460 (I still have both)
What had happened was:
A month or two ago I accidentally tripped the switch on the surge protector while the computer was on. The motherboard did not make it. I replaced it a month later with an identical one because I needed my stuff back and it was cheap, I'm saving up to build an i7 later this year. This worked just fine for a few days. Eventually I noticed my graphics card was starting to glitch in game. The symbol sprite sheets and textures would invert and plaster across the screen. Eventually the computer would blue screen and the dump logs said nv4_disp.dll was likely the cause. Just to see if I could fix it I did several things such as format and re-install Win XP (which was 32 bit) and install/uninstall the 250 drivers.
*At this point I updated the BIOs to see if that was a problem*
Eventually the blue screens stopped, but the computer began to freeze and force a hard restart. I had about 1-2 minutes of usable time before it would freeze up. I confirmed that this error only occurred when the drivers were installed. I could sit all day in 1024x748 without the drivers but if I installed them again it would freeze. As a result I abandoned hope on the card and got a new one. An EVGA GTX 460, which I was going to buy anyway for the i7 I'm building later on this year. Now in Windows XP and in Windows 7 the drivers of the 460 will act as if they are installing but on restart they don't activate and in the device manager the card says it has reported a problem (code 43).
What I've done:
-Sat on NVIDIA live tech support with Sanjib for 2-3 hours two days this week.
-Tried a million different drivers both WHQL and beta drivers.
-Tried updating the BIOS and whatever associated drivers (but there are no on board graphics so the only drivers are to the Ethernet port and for if I want to RAID)
My guess is that the new BIOS doesn't like the GTX 460, or I've done something terribly wrong. Any ideas and support would be greatly appreciated. I miss gaming on my desktop. I can access the older BIOS versions. Should I try going backwards?
