Computer crashing while in games (more info in post)

Ok, so like i said its crashing while playing games. I have the i7 2760qm and the Nvidia gt 540m 2gb with 8gb ram. Recently while playing Darksiders 2 and Guild wars 2 the computer runs the games fine but randomly the computer crashes and the screen goes into different color schemes like black and green checkerboard or purple and blue checkerboard and i cant figure out why. I have stress tested my CPU to over 105 Celsius without crashing and my GPU isn't crashing at 85 Celsius(yes i stress tested) this is confusing me because while playing the games i randomly tab out and check HW Monitor and the GPU never max's over 78 Celsius and the CPU's are around 95 Celsius. I have yet to figure out why these 2 games keep causing crashes. I have re-installed both and that didn't fix the issue and i have tried multiple different Nvidia drivers to no avail. Any input on this problem would be a great help and much appreciated. If you require any more info just ask and i will be happy to provide it.

 

What you are describing seems to be a GPU issue,

it well may be the problem is with the GPU memory.

I would consider a fresh thermal paste and thermal pad replacement on the CPU / GPU.

 

sorry it took so long for me to read this i have found an issue that i think is the cause of my problems. The 2 new games I downloaded and installed were on a corrupt or broken portion of my hard drive. I have already applied new thermal paste for the GPU and what would cause the GPU memory to cause this issue if it doesn't happen while benchmarking/stress testing. I'm fairly certain that my issue is the corrupted area on the hard drive and atm im working on moving the files i need right now to a different part to see if this will allow me to play the games. If they run then i guess my issue is the hard drive and ill have to get a different one.

edit: ok well i didn't realize u just posted that i figured it had been earlier since i haven't been able to check all day

 

I seem GPU memory fail due to heat related issues, and typically the fault is seen as corrupted or locked up screen video, much the same as your HD corrupted data shows.

Anyways if you certain it is your hard drive, then definitely time for a new one as the data loss will only get worse, and you risk possibly losing the entirer drive contents.

 

It does seem to be getting worse already, after i moved the 2 games and they worked for well over 6 hours at a time today i got the screen error again and this time is was red checkerboard not sure if the colors mean anything but it was weird i have to test it some more to see if this occurs again or if it was an overheating issue, its hard to watch temps in a full screen game : (.
