I recently installed a Geforce 7800, and it seemed to work fine for a while. However, for the past 2 or 3 days, when I turn my computer on I get an intel auto boot thing instead of it going into windows. I can enter setup with f1, but hitting f4 or f8 will not start safe mode or boot options. I did not alter anything in setup, but looking around it seems that my hard drive is no longer being detected. Oddly enough, after a couple restarts yesterday windows DID load, and I was able to use my computer normally for about 2 hours. Then it froze, and I got a blue screen: KERNEL_DATA_INPAGE_ERROR. After a few more reboots, windows would load, and shortly after lock up with the same error message or a similar one: fatal error. Now, it is back to the original hard drive not being detected. The only thing I know I did differently a few days ago was attempt to update the video card drivers. I have an older gateway, with intel p3, 756 RAM, 40GB seagate hard drive, and a sufficient power supply (400W?). Any ideas before I go Neoluddite?
