Windows 2003 Server, SP2, Enterprise Edition. It will power on but no video. It has been a week of attempting to diagnose a hardware problem with Dell. Original problem starting last Monday morning was that it would run fine all day, we would come in the next day to amber blinking light and server hang. I could restart it and it would reboot and run fine until next day. In the process we updated BIOS and firmware. Dell thought my problem was unsupported PCI ATA-100 3ware 7500 controller card hosting 4-IDE drive RAID. OS installed on drive separate from RAID array. Weekend came so I stripped it down to check to see if taking out offending card made any difference. It didnt, but it would still boot - so I put it back together - everything checked out and I went home saturday night. This morning I came in, flashing amber light, server is hung. Now try to reboot, fans come on drive light is green but no video. Video is built in. Ive tried a different monitor but no. Needless to say, I can't boot from CD drive either. There is a green light on the board. I have been researching this like crazy but I have not tried changing board dip switch settings or changing battery. I need this machine up tomorrow morning - I'll go in 4 hours early to catch Dell Support if I have to but... Any ideas? Thanks for your help!
