    I also had these strange shutdown problems until I replaced the PSU. First, I replaced it with the same model (same brand) and it kept shutting off. Switching to another model of a different brand completely solved the problem and my system has not shut down (by itself ;-) since then (several months).

    Regards!

    heat heat heat..... is the only thing that came to my mind... could be failing fan on psu ( which was my case, so double check that the PSU fan is running).... then the cpu fan, even tho its plugged it, it will not report any beep codes, only unless you have it monitored by bios. I had to rig up an 80mm on the PSU, warranty was out, and i wasnt going to get into the task of tearing it down, once i did that, no shutdowns. This happened a year ago or so, same psu with rigged fan still workin' .

    Windows 7 automatically shutting down


    I found that the power setting is not working quite right. Go to power settings and set the system shut down to never, monitor shut down to 15 or 30 minutes what ever you like. The system will hibernate with no problem.

    try this


    go into system in the control panel, go to advanced settings>>advanced system settings>>startup and recovery:Settings and turn off automatic restart.

    then stick close to your computer, when it does restart, look at the BSOD

    after I did that I noticed the BSOD said "END_OF_NT_EVALUATION"

    I think you know what to do after you get that.

    worth looking into.

    Random reboots or total shutdowns are usually attributed to the Power supply, overheating issues, RAM problems, motherboard with bursting capacitors or just any flaky motherboard, and sometimes even a hard disk drive.

    Guess & test by removing all extra components from your system EXCEPT CPU, PSU, GPU, 1 stick of RAM, DVD-ROM. Boot into memtest and run a check. If that's ok, plug in your HDD and boot into windows. This entire time make sure the components have access to air and are not hiding in a corner behind your desk.

    Is this solved yet? or are we just beating a dead horse?


    i just re-read the OP and I change my vote to PSU. go into your bios and check the voltages that are being reported(write the averages over about a minute down). and then google the tolerance limits, compare them to what you wrote down. if they are all about right, I didn't read enough to figure out what your PSU wattage was, but it's possible it's not high enough for your specs. add all your crap up in an online PSU calc, if it's accurate, the 7 CD may have a memory tester on it, i know mine did. Try that, let it run for 30minutes to an hour. Check for errors. It's probably not the HD unless there is a serious electrical problem with the HD, but you were able to unzip that 6GB john mayer, so unless it just has a preference to alternative rock, it should have crashed then.

    A bit late I know but hey!


    Right Click My Computer> Properties>Advanced> 3rd Settings Button

    Uncheck Automatically Restart then click OK.

    Now it won't restart if there are any errors.

    Nope, not the PSU...I have 2 completely different PC builds with not a single piece of hardware in common, and they are both shutting down randomly. I have absolutely no software installed (with the exception to vital drivers...video, etc.) except the copies of seven I downloaded directly from Microsoft's server on "Beta Day" I have the more powerful using 64 bit because it's got 6 GB of ram, while the old one that's basically just for browsing online is using 32 bit with 1 GB ram. I'm even using serials obtained when I downloaded the 2 copies...not some random serial posted online or anything.

    To further eliminate hardware failure as a cause, both my pc's were running both XP Pro and Vista Ult. with exactly the same hardware, and the same drivers were even used when they ran Vista.

    It's the exact same symptoms for my 2 pc's as in the first post, and now we're up to a count of 3 completely different computers (two of which have nothing but the OS installed) suffering from EXACTLY the same problem.

    BTW, mine are build 7000 (one 32 bit, the other 64 bit)

    I have been experiencing this problem,,, and i believe it may be due to overclocking the onboard graphics card.

    I disabled overclocking on the IGP , and so far no shut down,,, however i will post further results after some time.

    Ok it just did it again. But i have narrowed it down to Power supply or faulty surge protector.
    Im leaning toward the surge protector because the power-supply is a quality product, a Antec True-power 650w
    Going to replace surge protector ,, will update.
