ok. i'm writing this on a pda so bear with me.
i plugged in my new video card, and windows would hang on loading screen. i did a hard reboot to my comp. not turning on at all. i tried new power supply, different video card, reset cmos, everything.
now, i have diagnostic lights which are indicating a floppy drive starting; it hangs here. i have plugged in a floppy drive to see if that fixes it but nope.
