Hi,my graphic card is overheating while im playing games and my screen starts shaking and the pc turns off,i had my pc checked and i told them to install a second fan,they did but im still having the same problem please help.
Please list your graphic card so we can see the heatsink. You should be able to find an aftermarket one, but if I were you, I would rma the video card if you have some warranty instead of removing the heatsink.
May be your cpu over heating, I have same problem, my pc turn off while gaming, and found reson is cpu overheating, try some kind of software which detect temperature and while playing games press alt
+Tab and check temperture
