When the system restarts are there any messages at POST?Also what are you doing when it restarts? does it do at the same point everytime?Hagve you check you have your CPU heatsink and fan sitting properly?
Restarts suddenly without warning and post at the end of boot. The reboot happens when I use the computer normally p2p or facebook. The case is well ventilated with a fan 12 "CoolerMaster supply more than 12". I've seen in systems management that the error is 6008 but the only patch available is for Windows Server 2003. The restart occurs every 2 hours and 1 minute accurate.Thank you very much
