I have an OptiPlex 990 that multiple problems after a power surge, so I replaced the power supply, motherboard and installed a new hard drive. Once I got everything put back together, I booted up the system and tried to update to the latest BIOS, A19.
The prompt said it would replace X17 with A19. During this process a error prompted me that A05 must be installed first. I did that and got a "Bios Update Successful" message. but the PC did not reboot. After messing with removing cards it does not POST, just reboots a few times then hangs. I can get it to start by clearing the CMOS by removing the battery, but once I exit Setup or try to launch diagnostics or boot from an OS disk, the machine just restarts and hangs with the numbers 2,3,and 4 lit up with a blue Power LED.
Any Ideas as to what I can try short of calling this one dead as well and getting another motherboard?
Thanks,
