I opened the PC to clean out the dust bunnies. took out the graphics card (didnt take the fan or heat sink off the card) , processor heat sink and cleaned them then put them back in. Also got the dust floating around the case.I put a hoover up to the back and sucked all the dust from the fans that was blocking the holes.
Now When i log on to play games, the temp skyrockets, it got up to 105 degrees before i logged out. Checked fans etc and all are spinning. It seems fine if i log in and look at a wall or just surf the net or youtube but soon as i log in and move around it rises fast. It has been working fine for over a year at least until i clceaned the pc
Its a BFG Nvidia GeForce GTS 250 OC
