Unhappy Computer running fast then slow then fast

Recently my computer has been running slow. When i start the computer its nice and fast when i play games it's fast for about 10mins then it starts to get slow then i alt tab and go back into it and it's fast again for 15secs or so. It has happened before but i somehow fixed it by clean out the dust. This time i have done the same but it did not work. I have used ccleaner cleaned it and i believe it's not overheating because the weather is pretty cold around here. Anyone can help me please.

Some of the info i found on the side of my computer:
Intel Quad core (R) Q8200 2.33GHz 4MB Cache
4GB Dual Channel DDR2 800MHz Memory
1TB SATA 3GB/s Hard disk Drive NCQ
Dual Layer DVD R/RW 20x
NVidia (R) GeForce (R) 9400GT 1G PCI-E Graphics
19 in 1 Media Card Reader
Silent Case Fan
Runnig Windows 7

The outside weather being cool does not mean your CPU/GPU are cool. Download HWMonitor, and show us a screenshot while you are playing your game, to see how hot it really gets.

Your video card is definitely overheating (115C), making it throttle down.

Yeah, you can clean it, that might help a bit.
What is your case?

Just go get some canned air, take the side panel off, and blow the air into the CPU heatsink/fan as well as the GPU's fan. May be easier to work on the GPU if you take it out of the computer (usually 1 or 2 screws to dismount it, and just slide it out of it's slot).
