Is my GPU damaged? If so, is there anything I can do?

[TheGameNerd]

So very recently I have started noticing very weird things happening to my laptop. First of all, since a few months ago, my FPS in games has dropped significantly. My laptop is a gaming one, so this came as a surprise to me. It suddenly had started struggling with games it could run fine previously.

Laptop Specs:

Core i7 Mobile 2670QM @ 2.20Ghz Turbo Boosted up to 3.0Ghz
NVIDIA GeForce 540M 2GB
8GB RAM
64-bit Windows 7 Home Premium

I used a temperature gauge, and found out that my GPU gets to about 100 degrees when playing games like Minecraft, and it's at this point when I suffer a major FPS drop. This is the same for other games as well.

How do I fix this? How can I keep my GPU cool if it's a laptop GPU?

Maybe the laptop/fans are struggling to keep it cool, probably due to a build up of dust. Try cleaning it out and see if that fixes it?

Or is the fan still working properly and pushing the hotair out from the exhaust?

As mentioned may be dust build up and card is throttling back. Does it get enough ventilation when you use it?

Sounds like it's getting too hot!

Sound like heat. You will be seeing a fps drop as the components throttle back to stop themselves being damaged by a build up of heat.
This is one of the big problems with gaming laptops.
Get yourself some compressed air and clean the laptop vents our with it, be careful not to spray for too long at a time as this will cause condensation to form int he water from the can and this can damage components
