computer problem my computer shuts down during installing programs and uninstalling progarms need an answer?

Answer 1

most of the time you can reload back to the factory level,by a backup built in the computer or a backup disc,and that may resolve your problem

Answer 2

you probably have some kind of trojan, my computer used to do the same thing, when your computer turns off does it come up with a blue screen indicating a memory dump and then ask you weather or not you want to send a report to microsoft? if it does, send it and if it is a trojan then microsoft should know about it. (but you cant always be sure with microsoft)
