Howdy folks, got a bit of a problem. I recently installed a new motherboard/ processor (AMD Athlon 64 X2 4200 and a nvidia Neo2 Platinum mobo) but the problem is my graphics card. I did a clean install of XP and it starts up with basic drivers. I've installed the new mobo drivers but whenever I try the latest nvidia drivers the screen turns off and I have to restart. On reboot it does the same and the monitor says 'no input signal'. The card is an Inno3D geforce 6600gt. Any ideas?
