HL2/CS Source video problems

[konakona]

I have done some searching on my own to learn this has to do something with newer unstable nvidia drivers for most part; however, my card is an ATI 9800pro. The thing is game ran fine for a while, then stopped working abrutly after a certain point. I am guessing this might be either due to one of steam updates or refreshforce. Can refreshforce prevent game from running even when you dont specify the Mhz and just go with "auto populate"? Keep the ideas coming, thanks in advance.
