rebuilding a computer after a failed motherboard - went together well - windows 7 but if I connect the sata drives and boot the drive to the OS and let it sit - it shuts itself off after nine minutes. Disconnected both drives and it sits at a request for boot device for hours - no shut down. The drives are new - mb is supposed to be new - replaced by manufacturer - Just in case we replaced the power supply - 750w but it still turns off. Even happens with just one drive attached or either drive attached. The drives are new. The drivers are the latest.

mb is a GIgAbyte GA-Z87-DS3H (rev. 1.1) 16 GB ram corsair 2 brand new seagate 1tb sata drives

Can anyone explain this behavior? - I am suspecting the motherboard AGAIN (last time it lost its ability to recognize usb devices). Been searching for a solution but most of the time users implicate the hard drive but I think I have eliminated it - the chance of both hard drives being bad out of the box is rather a stretch - appreciate any comments or ideas?

Yeah, 89ºC is too high, ideally you should not go above 70ºC in extreme cases (stress tests like Prime95), on regular high load (gaming, video rendering) you shouldn't go over 60ºC~

Before pointing to the motherboard, any chance the PC is going to suspension mode? change the power settings to disable suspension/hibernation modes.

Since you've already changed PSU if the problem persists then it looks like you're having a bad time with motherboards.

no suspension - the computer goes dead off - total power shutdown - in fact I attached a regular table lamp to the surge suppressor to make sure we weren't losing power on that circuit. Lamp stayed on - pc shut down after 9 minutes - again.

no thermal errors noted but I will go down and review the silent settings to make sure I would see them and report back

thanks - gives me something else to check

well after some investigating this is what I found. CPU temp warnings were off - I set it to 60c (lowest) and ran it for a while - it shutdown several but never threw a thermal error. But when I go back into the stats the CPU is at 89c which is way over spec for my understanding of an I5 processor. We had a little issue reinstalling the heat sink - so we are reordering a heat sink and will check in when it arrives but seems like you are on to something here. Wonder why the mb doesn't throw an error.

89c is too hot - right?
