Okay, my MIL gave me a Dell 580s tower with some important files. Didn't come with the original power cord, so I purchased one to try my best to retrieve the file. However, it's not booting, and it's not displaying anything. I tried the power button, but nothing. I can say that the power button blinks orange for HOURS, and it beeps 5 times every minute. The fans are operational, though. I still can't get it to boot up or power on. I don't see any damage on the board. There is a minimum amount of dust, but so far, I can't figure it out. HELP!
