I just bought a Gateway gateway dx4870 ub318 and when I installed my above mentioned graphics card, it worked fine. It then updated the driver to the 3.10 I believe. Now when I try to start the computer, nothing but sleep mode for the screen.Not even bios splash screen comes up..... I tried the card in an old computer and it works fine. I uninstalled the Nvidia update but still no go..... any thoughts?
