I have a cousin who runs Intel core i3-4130 3.40ghz cpu and gtx 550 ti, he had this build for about a year and since he's pretty young he didn't care about his case cleaning. Few weeks ago he told me that his games which were working fine are now performing in slow motion like action. I immediately told him to download GPU-Z and we found out that his GPU was working at 98 C temp for the past 2 days (100 C is max for that GPU). I told him to clean it and he did so. He blew out a hand full of dust and that changed only the temperature, it went down to 70C which is normal for the gtx 550 ti, but the games are still running in slow motion except things like LoL, Smite, Borderlands 2, Starcraft 2. Things like mortal combat X and Dragon age:Inquisitor are impossible to play which were performing well before this. So I want to find out what's causing the slow motion effect, computer needs cleaning or GPU has suffered too much damage?
