Tonight I went to sort out a mate's PC, it is an AMD XP2000+ with 512mb DDR ram with a 40gb HD and has XP professional. His main problem was Hotbar and TONS of pop ups, got rid of this lot with the usual Adaware and Spybot. However when I came to re-boot it would not do so..... Windows goes through the motion of saving settings... the HD led flickers then nothing..... at first I waited 10 minutes but nothing, so I powered it down and restarted the machine. Upon re-boot XP did not say there had been any serious problems etc and worked fine (minus pop-ups). The computer will not restart, go into standby or shutdown without me switching it off manually. I asked him how long it has been happening and he said about a month, he has not installed anything or added any new hardware (he normally asks me to do that). I am assuming that it is an XP problem.... does anyone have an idea? All suggestions greatly received..... Thanks.....
