I am new to this tread and am not very computer knowledgeable. So anyone wishing to help please speak slowly. I have an older Dell which came with Widows XP, I still have the reinstall disk. The computer is a second one. When I turn it on the Dell screen comes up then the screen goes blank and then it says <windows root>\system32\NTOSKRNL.exe is missing or corrupt. If I tun it on and hold F8 down I get a message: keyboard failure, strike the f1 key to continue, f2 to run setup utility. Striking either key does nothing. If I turn the computer on and hit the f8 key about every second I get Windows Advance Options. I have tried to use most of the options and on each one it continues to where it lists Windows XP Home Edition, where I hit enter. Every time I get the missing or corrupt files message. I have placed the Dell reinstall disk in each of my slots and still all I get is the missing or corrupt files message. Is there hope for me?
