I can't run video files. CPU usage maxes out. But when I do anything else, it seems fine. I just recently bought an nVIDIA GeForce 7600 GS. I hope I'm doing this right.. I have Windows XP proffesional AMD Athlon XP 2200+ 1.80 GHz 512 MB RAM 450W power supply and I think 4 or 5 hard drives? Don't yell at me please ^^; I tried to download the latest driver for the card and it tells me thet it is not window logo certified and that if I install it, it might damage my computer. Can anyone help me? It would be greatly appreciated.
