Hi there again after i did the fresh install of vista somewhere along the line i have fiddled with the boot up procedure i think it was in the bios when you hit delete, now when i press the start button the psu and fans start the screen goes through the memory check then the screen goes blank,and when i click restart on the other button it boots up as normal,can someone tell me what to do so that when i ckick start it starts and when it needs to reboot it does that .Thanks again Rob.
