Hi Everybody, I installed a new XFX Geforce 5200 256 bit card. When I boot up the machine at post my machine freezes. I cant get into the bios at all. I upgraded the bios on my MB which is a Giga-Byte GA-7N400-L. My old card works but when this new card goes in thats when my machine freezes up. I have taken my sound card out I put in new memory and nothing has helped. Any Idea's?
