I have an HP Intel i7-3770 3.4Ghz
64 bit windows 8
I have installed the drivers for the Radeon hd 7750 and then installed the card. When I turn power on the computer beeps 6 times (so graphics card problem) and the screen doesn't turn on.
I have changed the power supply to a 520w but still no affect. This card works on my old pc which is inferior to this one by 2-3 years.
