My friend (which knows nothing about computers) was having horrible problems with Win98SE locking up everytime he did anything on the computer. So I just told him to get WinXP Pro in which case he did. He brought it over so I could format NTFS and then install WinXP pro. Everytime I got to the formatting stage of the install I got to about 2% done and then I got a "Stop" error. This requires a hard boot to restart and you basically have to start over. I immediately thought that his hard drive had bad sectors or something so we went and got a new hard drive and it got all the way through formatting the Maxtor 60 GB 7200 RPM hard drive, but when it was copying files it then got a stop error everytime. I do not understand what it could be now. I swapped memory that was not it. Any ideas? Its an older AMD K6-2 probly 450Mhz with a via chipset. I'm just trying to help my buddy out, the computer was bought off of the Home Shopping Network so you know they know nothing about computers. Let me know if you have any ideas, thanks.
