Hi, I recently purchased a ASUS A88X-PLUS mobo from Newegg and when I power the PC on, I get no display. Just black screen.

During the POST, the mobo speaker makes 1 long beep and 3 short beeps which indicates graphics card issue. But it also does the POST success short 1 beep after.

Is the graphics card dead? It was working before I switched the mobo. All my PC fans spin up including the GPU fan.

My graphics card is the Radeon HD 7750 which requires no external power, just PCIe power from mobo.

Also, before all of this, my PSU died last week so I got a new mobo along with my PSU as an upgrade since I was going to be buying stuff anyway. Is it possible that the PSU dying took out the GPU with it?
