I recently upgraded a computer that is running Windows 98SE. I added another 256 MB SDRAM. It originally had 128 MB. Now for some reason it hangs up on the HP Startup screen. It'll boot after awhile most of the time but it seems sometimes it just freezes. Any clue what may have caused this? Is it that it is simply counting the memory still and because it has 3 times what it had originally and its only a 600Mhz machine or so that it takes forever? Any ideas?
