Hi all, i have a crappy problem. Yesterday I bought a Radeon 9250 128mb (AGP) to play Project-Entropia. The game requires 64mb of video. I have an Intel P4, 2.8ghz, 512 ram. The problem is that i can play for like 30 seconds, then the screen freezes and the PC collapses and restarts

. Sometimes I can still listen to the music in the game but looks like the screen is disconnected, like it gets no signal from the pc. I installed the card and changed the bios from PCI to AGP.
Also downloaded the latest drivers from the ATI page, but I get a cli.exe error and the catalyst can't start. Something like "exeption error (0x000...135)". Even without the drivers I get the same crash error with the game.
I have tried all the available drivers and still nothing... I really want to play!!
Could someone help me please? I'm not a pc expert, just know the basics.
