|Very recently I noticed my computer refuses to boot up when I use startup > restart or a software update tries to restart my computer once it finishes installation. I have no problem booting up when the CPU is off and I power up, but if I restart I have to force shutdown and then boot up from a powered down state. When it restarts the mother board makes a 2 second long continuous beep instead of the normal single beep when the CPU power is turn on.|
I've narrowed the cause down to the display drivers- any of the versions for my gfx card (nVidia 9800 GX2) seem to cause this. I have deleted my entire partition, wrote zeros over the entire drive, flashed the bios, everything my brother and I can think of. From a fresh install of XP, with nothing loaded besides the motherboard drivers the computer will restart fine. As soon as install nVidia drives my PC loses the ability to restart properly. When I boot up in safe mode, I can restart perfectly fine.
My guess is there's something wrong with my GFX card. Can I prove this is something the warranty should cover? Could this have anything to do with loose wires? Any help or advice would be much appreciated.
