Some time ago, I was hired to try and revive a server that died. It was an old Dell server that running as a Windows Domain Controller.
This was the boot up screen.
After a lot of research, I discovered in a forum that the specific SCSI card was prone to bulging capacitors. Obviously the dust doesn’t help.
So being the true geek that I am, I went searching through my pile and found the specific replacement capacitors and heated up my soldering iron.
