Just starting and trying to bring it back to life. It hasn't run for a few years. I bought a replacement motherboard way back so there's a possible problem. Have not taken anything apart. But first this question....it came with Win ME...was upgraded to XP. I've heard it won't go to Win 10 but is there anything more recent than XP which will work?  I'm ok with XP but just wondering. Thanks.

I have the original packing slip.
