I am having an Intel DX58SO motherboard on my desktop computer system and i was running windows os on this machine. But when i tried to boot my system next day then motherboard showed lights and fan started running but there was nothing on screen. Suddenly my system gets rebooted and got an error "The system has detected unsuccessful POST attempt(s). Possible causes include recent changes to BIOS Performance options or recent hardware changes." and press Y or N for bios. I pressed Y and reset BIOS and changes XMP to 1. Again on next my system showed me same issue. Why it is not remembering the settings?
