I have a new D850GB mobo with a 1.7 Ghz CPU.. 423 socket. got everything installed in it updated the bios and every driver that i could find but if i do anything like open IE or jsut a folder it locks up. if i jsut leave the PC on it's fine. I've tried everything from changeing the AGP card modem and put 2 new fans in the tower and it's still freezing up.. Anyone ahve any other ideas what the problem could be. Should also add that this is a brand new Mobo and processor.
