Read this link on how to handle this.
my computer started powering itself off last friday... I would be in the middle of something and it would just shut off. at first I thought it was my computer over heating, but I've come to the conclusion that is not the case... because every time I try to run a virus scan, adware se, spybot, or any other removal software as soon as the software starts scanning the computer shuts off... The powering off got a lot worse after I tried to delete a process and I got the message "windows will shutdown in x seconds" and something about NT Authority which I know is a trojan... I've been getting tons of different messages... One being that windows needed to close to protect my files & folders, this message suggested I restore my system to a previous date when it was working correctly... Which I did this morning and it still is shutting itself down... I also got a message on start up that I need to reconfigure my system, but I'm clueless on how to do this... Now my computer is running, but everything is messed up the screen is super little, and I cannot check my Microsoft Outlook mail b/c it will not accept my password... I also cannot open any software programs such as adobe illustrator or photoshop.. any insight would be greatly appreciated...
