after putting togather all componets...amd athlon xp 2000+,asus a7n8x mobo,wd 80 gig 7200rpm HD,lite on 16x cd/dvd, floppy drive, gainward nvidia gainforce3 Ti200 video card, ocz enhanced latency ddr 3500.. when powered up the fans work great !!! power led lights and hd lights come on but nothing on the acer monitor except a steady power light indicator that soon starts flashing but no visual text on screen. I realize it could be a million things but my son has checked all jump settings and connections and says they are all true to the specs.This is his first atempt at doing this so any help from you-all would sure help.
