I was trying to install windows xp on my son's laptop.... said I didn't have enough memory, so I told my son to delete things he did not need...after deleting some files and attempting to restart it ..... he must have deleted something needed because now computer won't even start up.. I don't have any recovery disks for it. I can't even get it to power up..it's stuck in a hibernation like mode..Is there anything I can do or is it just a paperweight now.. I appreciate any help you can give me......thanks in advance........
