Current setup: AMD Phemon 9750 Quad Core Processor 2.40 GHz 8GM RAM 64-bit Windows 7 300W Power Supply
Recently had trouble where my comp would turn on, but no signal to the monitor, and just a series of repeating beeps (1 long followed but 2 short). So far I've gotten around that by bypassing the graphics card and plugging straight into the motherboard. This led me to believe my graphics card was dead, so I bought a new Radeon HD 7750.
When I plug this into the computer and hook up the monitor, the system fully boots up properly (including twinkly noise of a successful bootup) with no error beeps, however I get no signal whatsoever to my monitor.
Went into BIOS to see about disabling the onboard graphics, but the line that I believe handles this is greyed out. I've uninstalled the previous drivers. Could this be a power supply issue from my lowly 300W? The fan on the card runs so I know it's not completely void of life.
Any help would be great! I'm not too computer literate so please keep that in mind in your answers. Thanks so much!
