hello, i have a desktop pc(packard bell) which is about 6 years old, had new hard drive fitted about 6 months ago, loaded with xp home. pc as been fine, 2 days ago i was just checking my emails, i closed down the web browser ie8, and the pc shut itself down and then reboots itself. it will load up my desktop page with all the icons then straight away it will shut down and reboot in a continuous loop. i have started it up in safe mode and it stays on fine, i have tried all the options in safe mode, but still no joy. i do not know what to do from this point, can anyone help me please? i also need to rescue all my photo's which i can access through safe mode, but it will not let me copy them to disc, so is there anybody who could give me some advice?
