ok my PC failed. I discovered that the chipset fan on the MB was faulty, likely causing it to over heat. So i removed the fan and heat sink that came on the board (ASUS A8N SLI deluxe) and installed a zalman heatsink in its place with a new case fan at the front blowing accross the MB. Getting the heatsink in was very tricky and i made 2 attempts before it fitted up correctly. So then i went about installing XP, all was fine until i went to install the display driver for the video card. I got a message at the installation saying that setup could not find the correct hardware or software configuration. So i open the case and make sure the video card is secure in the slot and try again, same result. I then disable the system set VGA driver and restart. Now the operating system goes as far as the xp logo screen on startup and then goes black, whats wrong, please help....................
