I got a pc that needed some tlc.? I reloaded it with win. 2000 pro. and tried to connect to internet with my usb port.? Since it wouldn't work, I decided to reload the computer.? Now, it continuously reloads, will not start up, and always says "couldn't open boot drive to check for signature".? :banghead

What did I do?? Yes, I messed with a lot of stuff, checked jumpers, etc.? I even put a floppy drive in so I could try an emergency disk to start-up.? No such luck.? Please Help
