Hello there, I'm not the most computer savvy person so bare with me through this procedure. Last night I started to hear things, strange noises, adverts and such. I restarted my computer and it didn't continue to do it. Freaked a little by the incident I decided to install an anti virus, that one being MSE. Once installed, my computer just shut down with the "Critical error" message. Now when I turn my computer on I don't even have the time to install a program or check files, because it's always rebooting. If there is any advice you can give me I would be extremely grateful. I'm using Windows 7 Home Edition, 64bit if it makes any difference.
