Hi. I have the computer in my sig. The biostar motherboard stopped displaying the splash screen and the cmos. I reset the motherboard using the jumpers and everything seemed cool and it displayed correctly. After reaching windows, I rebooted it so that I could plug in the remainder of peripherals. Now its not displaying again. There are no bios updates for my system, the only ones are for semprons and x2s, which dont apply to my situation. Could it be something conflicting? Yesterday and every day since thursday, when I built it, there was no such problem. It boots into windows okay, but I dont see any bios display.
:banghead:
 
Monitor connected to the right connector? (in case of dual head card, most are nowadays)

You could try connecting a TV, I've seen similar situations where TV's did show the BIOS output.
 
It could be possible its displaying on my svideo... I guess I should give that a try.
