Hey there, So, I bought a new graphics card and installed it. Old card was a Nvidia Geforce 7900GS, new one is a Gigabyte Geforece Series 9500GT. Now, my computer won't boot up, claiming 'reboot and select proper boot device or insert boot media in selected boot device.' I'm running XP. I can get into my Bios, but nothing seems to help. I CANNOT get into safe mode, no matter when I hit F8. I've read in some forums that sometimes the hard drive is not recognized, and this may be the case, since in my Bios Boot menu under HDD Broup Boot priority it says 'not installed'. My old graphics card had a slot that the hard drive plugged into. The new one does not, but even switching back to the old does not help. Any ideas?
