Step 1: Turn your PC on normally. Step 2: Press f8 and go into safe mode. Step 3: When you're in safe mode, go into device manager and disable your video card. Step 4: Restart computer(don't go into safe mode). Step 5: Flash your card like you normally do. Step 6: Go into device manager and enable your video card. Step 7: Restart pc and it will work. I found this method when I flashed my 4870 and restarted pc by accident. This method worked for me when I was using a ATI card, can someone confirm that this method works for Nvidia cards. I posted this on OCN and I might as well post it on this forum to help out others.
