Try putting it in and loading an OS onto it directly (Install XP Pro or whatever you have handy). Let the machine do the disk work fo you. See if it will boot that way. If it does, then you should be able to copy off the important files by hooking the old one up as a slave. It's a pain in the rear, but sometimes it's better to start with a fresh install of the OS.

replace the power supply-from a computer store, should be no more than 30 dollars

I believe resetting the CMOS would fix this problem. To reset the CMOS, open up the computer and locate a battery similar to this one (it's on the motherboard):

Picture

Once you find it, pull it out. Leave it out for about 24 hours (one day) afterward placing the battery back into its slot on the motherboard. Now try booting up.

It should now successfully start up requesting that you make changes to the BIOS since the CMOS was just reset. Afterward you should be able to use the computer normally.

NOTE: Try resetting the CMOS with the original RAM inside the computer. The new RAM might be forcing the motherboard to send too much voltage or use an incompatible Mhz setting to support the new stick of RAM.

Let me know how it turns out and if I can do anything else to assist you.
