I've built an AMD machine from another computer I separated out. Everything has gone well except when I right click on any icon on the desktop I get the hour glass and no response. This only happens on the desktop and nowhere else, I'm running win XP pro, Athlon XP 2200, tried 2 MB's, & 2 Graphics cards, using SDRAM 133 512MB. Has anyone seen this before? I've been building machines for years, some all new and some with used parts and I have never encountered this before.
