Windows XP stuck on Mup.sys

It has been a month since my friend's daughter asked me to repair her computer. At the time she said that first of all her computer was attacked by virus. Her friend divided the hard drive storage into two partition to save the data and made new installation of Windows. When Windows installation was loading, it stuck and the system hang. They don't know how it happen then they brought the computer to me.

My first try was switching the hard drive to my computer and reinstall Windows. It worked. But putting back the hard drive to her own computer result in the stuck problem when loading Windows. So I used safe mode. When it called for drivers, it stucked again on Mup.sys. I switched again the hard drive, placing my hard drive on her computer but it was still in problem. I suppose there was a driver which could not be loaded after Mup.sys. Then I checked any
cards and cables, making sure that everything fit well in their place. The result was the same.

My first try was failed. The next day I searched on internet about the problem. I found that many people has the same problem. Most of them agree that the problem is related with hardware. There are many suggestion given, i.e

- replacing power supply due to failed voltage supplying
- resetting BIOS
- removing USB device, etc
