Hi, ive just set up an NF7s with an AMD 2400+ (on all default\nsettings, no overclocking). Its runs perfect BUT now and then, when\nyou switch the machine on, it does the bios start up etc, boots the\ndisk drive but just when you'd expect the 'stating xp' screen, it hard\nboots. (ie right back to the monitor start up!) It then just repeats\nthis cycle over and over until I physically shut it down, and reboot.\n\nWhy is this??!
