Forgot to reply. Had to open the casing and move the power button which had got stuck. Machine powered up and then changed the BIOS settings. Thanks for your help. I don't know myself since I got my new PC. My windows is fully updated and patched, AV & Firewalls up to date. All I need is to buy a new monitor. Looking at a 17 inch flat screen, Dell or BenQ from Komplett ?
