this is usually as a result of problems where your hardware is concern and not really a missing file problem
Check between two things they should fix the problem if not then think about tshooting/changing some of your hardware

1 Motherboard. try to update to the latest bios revision.make sure processor is being cooled properly
2 Avoid overclocking before OS installation
its also good to remove any unnecessary cards/peripherals b4 and during OS installation then add them back after (Includes disabling onboard controllers too)
it could also be a result of a bad memory (get a dos boot diskette that loads himem.sys if any u'r memory bad then it'll say unreliable memory at {byte location})
