Q3 & OpenGL - HELP!

I have read all about the grey screen of death - how about the white screen of death.
Have PII 900 Mhz, Nvidia Geforce 2,256 RAM on Win 98. This freakin game just goes from one problem to the next. I have loaded all the latest patches and drivers. I used to get all the way to when the game tried to load the first map and then it would hang. so i loaded the lates Q3 patch from ID and now I get the white screen of death. Wots going on?
