I have a dell that has XP media edition on it. About 2 weeks ago it wasn’t booting up anymore. I tried booting in Safe mode and it hangs on mup.sys. I’ve searched online and found that the power supply is usually the culprit. I replaced the power supply and the same thing is happening. I removed the hard drive from the machine and placed it in another machine and the OS boots up with no problem. I’ve disconnected everything inside the machine except for the hard drive to see if it boots and I have no luck. The only other device I keep in is the USB mouse since I do not have a PS2 connection. Does anyone have any ideas or suggestions on this.
Thanks
