Hi, I am trying to install Windows Xp on my computer but it doesnt install. I am having problem with the copying files. I formatted the root drive C: so viruses can be removed, but still it doesnt install. Whenever the setup is copying files it stucks on 56% and then gives an error that the file is missing press enter to retry or esc to skip. I pressed enter 5 or 6 times and then it gives error pfn_chk_list and my computer restarts. The problem was that my xp was running fine the other day but then i saw a error physical dump memory error. After that the windows was booting but wasnt showing any startup screen and kept constantly restarting. So i thought it would be best to format my 400gb western digital hard drive and try again, but the copying error came again. I have made four partitions of my hdd.Please give me a solution to this and reply as soon as possible.
