Overheating Laptop (Primarily the GPU)

Hello, This is my first time asking a question on this forum and I have found myself in a bit of a sticky situation.

For the last year and a half I have been happily using my Asus G74sx ROG laptop as a gaming computer, and I have been satisfied with the power that does not seem to be capable of defeat.

Unfortunately, I have found the downfall, Overheating. Using various tools such as GPU-Z and Piriform Speccy, I have monitored the heat of my GPU, which, at times reaches almost 95 degrees Celsius! This is noticeable when playing games, the framerate will go from the very gorgeous 90-120, and drop to 10 for a split second(I assume so the GPU can catch up?) and go right back up. This happens around 30 times per minute.

I have a hypothesis, Dust. I think dust is the issue to my problems! I intend to go out in the afternoon tomorrow and pickup some more compressed air so I can try to eradicate this evil dust. I am wondering if I should pursue dust as the evildoer or if I am completely overlooking something obvious and should slap myself.

I hope you guys are able to help me with this issue, and I thank you in advance!

I do intend to get parts to build a PC sometime soon (wish me luck on my first build!), but in the meantime, here are my specs:

CPU : Intel i7-2630QM @ 2.00 GHz
GPU: NVidia GeForce GTX 560M
RAM: 8 GB
Additional Monitor: Asus VS238H-P

*Edit (Fixed): I misspelled 'Laptop' in the title, shame on me*

Yes, If your laptop was working fine before and now it isn't I can only assume that the problem is dust. Using a can of compressed air should be sufficient. I however, always take the bottom cover of of my laptop and use a a vacuum cleaner to suck up all of the dust in the computer. Laptops and computers get dirty fast. I regularly clean mine once every two months.
I hope this helps.
Cheers :)

Taking the cover off the bottom and cleaning out that way is best. If the problem persists then it might be time to reapply thermal paste to the gpu.

Thanks for the reply, I couldn't get a can of compressed air today, but I will be getting one tomorrow and will try to remove as much as possible. I will get back to you tomorrow with an update on the situation! Thank you for confirming my theory!
