ok..you started all wrong. sure you can run windows on that computer, but start with an old pentium 100-200mhz box. install slack8.1 on there, you dont even have to run a GUI. buy a book or read through some docs
i started with corel on a pentium 166 with a 2 meg vid card and 32 megs of ram..i wish i would have started with slack on that box.
but, if your just beginning, dont start with linux on a fast computer....
the least you could do is run win98 or win2k.
