I am having problems getting my computer to post. It has a Gainward Geforce3 Powepack ti200 and iwill kk266-R. It will post 1 out of 25 times and will continue to post successfully after resetting it, but once you turn the power off it won't. I've tried a different MB with the Gainward card and a different videocard on the kk266-2 and they work fine. What is the problem? If somthing needs to be replace what would you suggest?
