No boot in to windows until you pull power away

[BruceMyers48]

I have seen this before, E-Machine does not boot, it goes to the E-Machine logo or asks for last known configuration then goes back to the E-Machine logo. I had a friend unplug it and bring it to my house and I plugged it in and it worked fine. I have see this before were you can pull the power away from the tower and wait 30 minutes or so and plug it in and it will work. What is really happening here?

Try clearing the CMOS. Also, could try another PSU
