Your other problems aside, can you play Star Wars Battlefront with a Radeon 9200se?
I have an Athlon 2.4 with a Radeon 128mB 9200se and it would only play on about two or three of the Battlefront levels. Then I adjusted my dislay settings from 32 bit to 16 bit and I could play a few more levels, about half of the 15 or so levels in the game. I then installed the game on another of my PCs, an Athlon 2.0 with an Nvidia Geforce4 64mB (both PCs have 512 RAM) and every level plays perfectly. Very weird, considering the drop in power. Next I'll try loading it onto my Intel 3.0 with Radeon 9800 and if that doesn't work then I'll know that the game was made for Nvidia (which is what it says when it loads). The Radeons work well with all other games (Half Life 2, etc - in fact, I switched to ATI graphics cards because of their superior gaming ability) so I think the problem may be that George Lucas has sold the remains of his soul to the Dark Side.
