Answer» Quote If you don't even get a POST screen (white writing on a black background) your PSU would be the 1st suspect. Yeah, that makes sense. Thank you. I just realized when unplugging those cables, that when I plug the power supply back in, it makes a really weird humming sound that I never heard before. Is it hard to replace the PSU?It's a simple task but if you don't feel confident you may be able to get a friend who can do it for you. Do you know anyone who would lend you one to try before you purchase one?USUALLY only four screws once the case is opened and unplugging and replugging wires. http://www.google.com/search?hl=en&q=how+to+change+power+supplySo I got a newer power supply (one that was in a computer that was BARELY used), figured out how to get it out. Took the power supply that I figured wasn't working in the problem computer... only to realize that the two power supplies are different so I can't even hook the other one up to the problem computer to try it. I put the power supply back in the problem computer for now, and it powers up so I didn't ruin it. Now I'm confident that when I get the right power supply I'll be able to switch them. It'll be a few days now before I can post an UPDATE to see if that will work. In the mean time, anyone else have any ideas?No further ideas are NEEDED as you are on the right path...don't let them talk you into a cheap PSU...they're kind of an important part of a well running machine.Did you try swapping the videocard yet? I'd reset the CMOS. Just to get things straight: The PC does power on, right?The PC powers on, but the only thing that SHOWS up on the monitor is that Self Test Check Your... message.Reset the CMOS.
