Does it have a floppy disk drive? Is the BIOS maintaining the date and time and retaining its settings when the PC is off? I'd double check all your data and power cables to make sure you haven't knocked something loose when you replaced the power supply. At one time Dell didn't use standard off the shelf power supplies. You had to order a replacement from them or rewire a standard power supply. I don't think they do that anymore but it wouldn't hurt to compare the wiring of the 20/24 pin motherboard power plug on the two supplies to make sure all the colored wires match up.
