I replaced my old video card with a brand new ATI Fire Pro V7800 today. I also removed and re-sat the memory. As soon as I started my maxhine back up, Blue screen. This was a "generic" blue screen.  Rebooted, 10 minutes later, BSOD, IQRL_NoT_......, rebooted, 15 minutes later, BSOD-page fault...... Rebooted, 10 minutes later, black screen - driver has stopped working ........ Rebooted, replaced driver, no BSOD yet but I keep getting the error about the dispay driver not working properly and now it doesn't correct itself. ANY IDEAS?

My system:

AMD Phenom 2 X6 1055T

8 GB ram

windows 7, 64 bit

ATI Fire pro V7800, driver 8.723
