I am using a PS2 kbd now.Still have the same issue. I loaded the optimized BIOS defaults. No change.
Here is the symptom (not any different from the previous sympyoms).
If using onboad video,can go to BIOS by using the <DEL> key.
if using gigabyte Radeon 6450 512MB card for hdmi, cannot get into BIOS.
when both vga and hdmi are coonected, I can press del key and it feels the compuer is enteing BIOS but noting iis displayed on either of the screens(tv,monitor) reboot when this occurs.
So, whenever I have the video card plugged in, I cannot access the BIOS and BIOS Setup.
