Alright, so I have GeForce 230 and I updated to the driver version 301.42, however the update makes my games lag after 5-10 minutes. (I have had this lag problem for 6 months now with all the previous updates in this time span.)
The games that I'm trying to play are Left 4 Dead 2 and Grand Theft Auto IV.
When I try to play these games, they seem to be running fine in the start, but after 5-10 minutes, they start lagging to the point where it's unplayable.
However, not all my games lag. When I play Counter Strike: Source, I have no problems, and the game runs smoothly for hours. The problem doesn't seem to occur with the "older" games.
I used to be able to play all my games without any problems, but it's after I updated my driver to 301.42 that it started lagging in these games after 5-10 minutes.
Throughout the time, I have been in contact with Nvidia customer support and they suggested me a couple of drivers but none worked.
I tried to clean my RAM but that didn't change anything either (this method: http://www.ehow.com/how_5068108_clean-ram.html)
I tried to run a Video Card Stability Test (the program with the 2 earths spinning) and my computer never froze or crashed after 2 hours of running it, although the earths did lag a lot at times.
Here are some screenshots of my computer's specs:

Here are the screenshots of the results from System Requirements Lab when I check if my computer can run the two games:

Any ideas what could be wrong?
EDIT:
Alright, so I cleaned up my computer and a lot of the dust is gone. Apparently there was a ventilation at the bottom of my computer which was full of dust:

I cleaned it all up and I just managed to finish an entire campaign in L4D2 without it lagging, which was maybe 30-40 min of gameplay.
The temperature reached a max of 89 degrees which is better from the 105 degrees I previously got, but I'm not sure if 89 is still too high?
