I've just got a brand new graphics card and was excited to start using it, but about a day after I got it I kept getting a blue screen saying "hardware malfunction, call hardware vendor for support, system has halted". But now I can't even manage to get passed the bios logo on startup, and on the one chance that I did manage to get passed it got stuck on the windows logo and then said hard drive not detected. Any help would be much appreciated.
