The GT430 is supposed to be able to get around 50FPS at max quality with 4xAA at much higher resolutions than this computer is set to. I've also stress tested the GPU before and left it running for hours without a problem. Temp after playing or leaving games running were still low. As for dust, when I manually checked the RAM a couple days ago, I had to open the case and I was actually surprised how beautifully clean it is in there (because it is so rarely used).
I actually just fixed the dll problem for L4D2 by deleting the bin folder and then re-validating through steam (which re-downloads the files). Now it will launch without an error message. I also updated Java and Minecraft seems to be running smoothly now. I'm going to leave it on for a while and see how it goes. Later tonight and tomorrow I will try more L4D2 and another game and see how that goes, but it is looking like I may not have to reinstall the OS after all.
Thanks for all the help, by the way.
