My PC refused to boot up today. I am running Windows XP, and it hung up right before the network login screen (the cntl+alt+del screen). It gets the blue background, and mouse cursor, but nothing else. I tried to reboot into safe mode, but it hangs up there also before the login screen. Next I tried to repair / reload WinXP using the Boot from CD and my system disk, but it gives me the following error: \i386\ntkrnlmp.exe followed by error code 7. Google search results give various ways to fix, but all involve copying the missing file into the windows folder, but thats not possible since I cant even get booted up. None of the BIOS settings were changed from my usual settings, and I have more than enough RAM to run windows unless they BOTH failed simultaneously. Any suggestions?
