Hello, I've got an older PE2550 (P3-1.13Ghz era) that's been lying dormant for about six months. We shut it down and it was fully functional. Today I fired it up after removing a 2nd SCSI controller, RAID controller and NIC which were filling the 3 slots. There was no video. The system does POST (drive spin up-they are empty), and you hear it beep the double-I-have-no-operating-system beep. Video never initializes. The display indicates no video. I swapped out displays to be doubly sure and it is still not working. I replaced all three cards so it was back in its original condition, no video. I cleared the BIOS (long shot, but what the heck), no video. Basically, zero video...any suggestions? Thanks!
