Quake 3 freeze... my video card? cpu? ram? drivers? ISP?

[Catpellets]

when I am playing Q3 it will all of a sudden freeze... it can happen when nothing is going on, but I still get no lag when 50 rockets hit me (besides ISP lag).... when is frozen I cant do anything.. at all... This happens with AGP fast write on and off, and on 64m mode or 128m mode (memory that the card can access and use off my normal SDRAM)

is this because of geforce is overheating? I ahve a OS fan, aftermarket not very good CPU fan and the video card has a fan.. and the side panel is off my case and it is sitting out in the open.. AOpen reads the card temp at about 47-49c after I get back into windows after a hard poweroff.. (47-49 celcius? isnt that really hot? i know CPUs shouldnt take that heat normally)

geforce 2 gts (AOpen)
epox 8KTA2
750 duron... and ... .. AOL...(ack...) and it also freezes me with the "connection interrupted" message and I can still see people dying and typing (I am assuming this is just my connection and 600-999ping.. am I right?)

I have the latest drivers for my video card also (the Aopen drives... how would I get teh creative drivers? or NVidia drivers? and how would I make the card use that instead?)
