No display on the bios and fan spin up really fast.

No display on the bios and fan spin up really fast.

Can anyone help me with my motherboard is an ASROCK G31M-GS. The issue is no display on the on-board vga and I get nothing not even the bios. I tried also remove the ram switched it back and forth and also bought new ram and get nothing at all. Also, change the CMOS battery and no result. Also tried two different graphics cards and same result nothing. Could have a dead motherboard or cpu.
