Installed ATI Radeon 5750 into HP m8020n = No Video Signal Tags: Radeon Hewlett Packard Video ATI Graphics Last response: August 12, 2010 6:05 AM in Graphics & Displays Share kprime August 12, 2010 5:54:55 AM Hello, My wife bought me a ATI Radeon 5750 and a new 500W power supply for my HP m8020n. I installed both but when I start the pc I get no video signal from either the DVI or VGA. When I put back original card works no problem. So is this card compatible with my PC?

Is the fan spinning (on the HD 5750) when you power it up? Can't find your answer ? Ask !
