A friend of mine recently purchased a XFX GeForce 8800 GTS card (320 MB) and a 600 watt PSU. He put everything together fine, but when he tried installing the drivers off of the disc included, he got a message saying that his card wasn't an XFX product and that he should try finding drivers for it on Nvidia's site. Whenever we try installing the drivers off the disc or off the site the system just goes to hell. If you try installing them in normal windows, the system hangs for a bit, and crashes, flashing a blue screen for a fraction of a second (strangely enough, not the blue screen of death). If you install the drivers in safe mode, it seems to be successful, but upon a normal boot, the system defaults with minimum resolution and color settings, and if changed to anything else, the system crashes. I know something is going on with the drivers, I just can't figure out what. I don't remember his specs at the moment (important, I know), but I'll post what I can, and get the rest later today. 512 MB Ram Windows XP SP2 Sorry again for the lack of system specs, but if anyone has some ideas, I'd appreciate it. If you need more info just ask.
That's an odd one, if it doesn't pick up the graphics card there's probably a hardware issue. Did he completely remove his old graphics drivers first? What 600W PSU is he using?
could also be a bad card as ran into that problem on a customer's brand new computer. try loading the driver & the system was extremely slow. if use no driver then was alright. also noticed pixels on the post screen but not windows screen. replaced card with new 1 & driver loaded properly.
