Maybe what he said too, I dont know spit . Your talking apples and oranges. 64 ram on win 98 se is a hell of allot of difference than the 256 you had . But you do have a point video and mouse often have conflicts in the IO ports as well as network cards. SO it matters what order you install them in. I do work on older machines allot and tec / fix them but i am no expert. Trying different video drivers can be a real nightmare and you can go places you might have one hell of a time trying to fix and get it back to what it was before and will end up reinstalling windows. Cenozoite admitted to sort of knowing what defrag was. That wouldnt bode well for the possible disaster you are sugesting.
