This is the screenshot of when I boot up my PC, I get this screen as it shown in the picture at the moment then it goes black but you can hear the computer is still running. At first I thought I had RAM issues, then I did testing on each ram stick, then found that was not. It's not the HDD because I tested both with the HDD and without it, same display. I thought it was my graphics card, so I decided to buy a new one, same issue.

**side note: I have no idea why my motherboard is displaying the wrong CPU ghz... I never overclocked or toy around my BIOS!

I disconnected my graphics card and connect your monitor to the onboard VGA connector and it goes pass the screenshot as shown and displays normal. So what's the real deal here, when I connect my graphics card, it goes black, without it, it goes through fine.. do I need a new motherboard or is there some other issue? Anyone know? would be great if there's feedback, thanks.


Also my specs are
CPU
Intel Pentium Dual Core E5200

Motherboard
Gigabyte S-Series G31M-ES2L motherboard

Memory
4GB Kingston DDR2 RAM

Videocard
(NEW ONEATI Radeon™ HD 5770) OLD ONE WAS 9600 GT

Have you set the primary graphics adapter (in the BIOS) to PCI-E?
