Started installing XP x64 the other day. All went fine till it started to install the devices. By the looks of things, it happens when installling the video card - ATi RADEON 9550 256Mb (AGP 8x). The screen flickers once as it installs, but when it flickers again, the screen remains black, i get no signal from the monitor, and the PC crashes. Anyone has any thoughts?? ---------------------- Windows XP Pro (32-bit) AMD Athlon 64 3000+ (SKT 754) ATi Radeon 9550 256Mb ECS 755-A2 Motherboard 2x 160Gb SATA Drives 1Gb Kingston Value RAM
