I recently bought an Asus HD7770 2GB Graphics card and put it in my computer as normal, i booted it up the first time, worked perfectly. The second time my screen didn't show up and memOK was on. I press it so it would do a scan and it found nothing to fix it. I tried putting a different card in there but it did the same thing. I tried cleaning it, and resetting the cmos but nothing works.
