Chosen Solution
My Laptop Specs are as follows; GPU: GeForce GT 525M CPU: Intel Core i5-2430M CPU @ 2.40GHz Memory: 4.00 GB Microsoft Windows 7 The problem is a few days ago my Laptop fell from my bed on to the floor. Although there is no apparent damage to the machine, now every time I run any game the GPU fan start to seed up as usual and when GPU reaches its peak the Laptop power fails. It does not shutdowns, the Laptop just turns off like some one pulls a plug on a desktop PC. I disassembled the whole machine to check if any part had slipped from its place due to the fall but none. And while it was open I also dusted off and cleaned the board. Reassembled the machine and ran it again. But same, it keeps on working for hours without any problem as long as you don’t run a Video Game.
it sounds like a possible overheating issue i would try to take it apart again and check the heat sinks, possibly replacing some of the thermal paste, if one of em got knocked loose the original thermal paste is not going to work the same, even if put back into place
You can monitor your GPU temperature easily with a program called “gpu-z” here is there website: http://www.techpowerup.com/gpuz/ Navigate to the “sensors” tab and you can see the temperature. leave that program open when you play a game and simply click the temperature box to change from current, min, max, and average temperature. @95C the video card starts to throttle clocks down to reduce heat and avoiding any possible damage to the card, or in your case shutting the laptop off.
