i did a clean install on a computer i just built and it took several hours last night to do the blue screen install of setup files. then it took around 3 or 4 hours to do windows setup instalation. Then after it was all done, the computer cpu usage was hovering around 100%. so i thought maybe i should reinstall windows. Im reinstalling right now and win xp blue screen setup is going and its been 45 min and im only 34% done. Does this sound right to you?
