My computers power supply is officially dead. I replugged in the dvd drive to see if it would work still, and it didn't. Unplugged it again, and it's still beeping power error.One more retry, and if it still won't work I'll buy that 650w PSU.
Can't you harvest a PSU from an old clunker? That's what I did, it worked great for years until I junked that computer.
