This could be casued by a wrong setting in BIOS. Next time you turn on your computer open up BISO, and i am not sure, but i think the option is under something about the chipset settings, if you find it you will see lots of differnet AGP settings. I am bad with names as you can tell :tongue2: but you should look for an option with the setting of 64mb or 128mb, if it sais 64mb then change to 128mb, if it sais 128mb then leave it. Sorry about not saying the exact setting name, but i am horible with names and i cant remember it lol. I just know that it is in the BIOS under chipset or something.
