However, a week later my computer... ah sorry it's an alienware aurora r4. Anyway, the fans started to suddenly rev up and down and it slowed down to a crawl. I panicked a bit a hit the power button, then started safe mode. I thought it was a virus at first since Avira picked up a type of trojan in the temp files though it was zipped (not sure if something like that can infect or not?)
It hasn't done that again but now there is a new problem. After a bit there is a heavy stutter for around 5-10 seconds. I noticed this most when I'm playing games but it happens even just browsing. It's mostly the screen as the sound doesn't seem to be effected but my keyboard doesn't work during this time. Odd thing happened one of those times is that it seemed to mix up some keys on my keyboard (the esc and windows key switched) and outright render others useless. The mouse still works though, oddly enough. I am running Windows 7 home premium.
Any help would be appreciated.
