hi, my ive had my new pc for about 1 year exactly now, and since my old pc has been gathering dust, i thought i would boot it up. however, whenever i turn it on it just restarts, and then just restarts randomly. i know it isnt a virus because i have just re-installed windows on it. any help much appreciated please! My computer is a packard bell ixtreme 9100 i, 384mb ram, 800mhz processor speed. it's running windows ME and hopefully when i get this problem sorted i will put Windows XP on it. thanks!
