I have a Gigbyte K8nXP-sli mobo.
About a week ago it started acting up and I lost the video signal. Tried subsituting a different monitor with the same results.
Immediately suspected a failed graphics card. Purchased a new one it arrived a day ago. Installed the new card, same results.
Tested PSU-ok, Tested RAM in another PC-ok, substituted CPU-no change. Unplugged all peripherals , still no boot up. Jumpered CMOS, no change. Replaced dead CMOS battery, no change.
When you turn pc on, all the fans work, you can hear dvd-rom check, hdd start, but there are no beeps and still no video.
Could it be a failed mobo?
