Hello! I really hope someone can help me as I am pretty green @ pc repair! Ok, my son turned my pc off without shutting down windows and it just never came back. I've tried to start from last good save or whatever and all other manner of futile attempts. I decided to just start all over and reinstall windows xp as an error message kept coming up saying windows could not start because a file, system>root32\ntoskrnl..that is as close as i can get from memory. So I reinstall successfully and it works for a day, sometimes 2, then crashes and I have to repeat the whole process. Everytime the message is the same as above. I'm at wits end here and know virtually nothing about pc repair. It took me 4 hours to install a new power pack in it a couple years ago so I'm no expert here. I would appreciate any help I can get!
