Earlier today I tried installing RAM, After doing so with clear instructions I booted my pc.. I got the message, Windows could not start because the following files is missing or corrupt: <Windows Root>\system32\ntoskrntl.exe Please reinstall a copy of the above file. I have looked at many other solutions to this, Saying I should put the OS disk in from boot, Open BIOS etcetera.. This never works And I cannot access anything at all. Please help? Is my computer totally busted? ><.. Much Appreciated.

I managed to get into the Setup Utility, But it still doesn't let me run the OS disk and find the missing file. Can anyone help?

Have you tried removing the RAM you installed? Sometimes hardware based problems show themselves with messages like you are getting that aren't really the problem. If all you did was add RAM then I suspect it might be bad and that is causing this error message.

Yes, I did so about 20 minutes from this post (now). Now my pc won't work at all. When I turn it on the tower makes about 5 noises and then stops, The monitor will not start either.. I have returned all cables to their previous state. One thing is that I MAY have forgot to push the DIMM pins down.. But I don't see how that could affect system start-up.

This may help if you can get into the recovery console. http://www.informationweek.com/story/showArticle.jhtml?articleID=185301251 http://computervitals.com/

Thank you for the link, But I do not have missing Hal.dll files and also.. I cannot get into the System32 or anything or file.. I am still stuck at the turn on screen thing.

"One thing is that I MAY have forgot to push the DIMM pins down.. But I don't see how that could affect system start-up."... Well. Are you sure that the RAM you installed was indeed compatible with your system? Not sure what the "turn on screen thing" is. Can you clarify? Life is more painless for those who are brainless.
