my computer turn off and reboot,could it be the cooling fans, fan #1 2733RPM FAN #2 0RPM FAN#3 11250RPM?

Question

ARE THESE FIGURE TO HIGH ARE TO LOW

Answer 1

Fan #2 is too low, zero is always too low. But that could mean simply that you don't have a fan for the #2 detection connector.

Windows by default is set to automatically reboot upon system failure, and there is therefore no "blue screen of death" aka BSOD that shows up when your system fails. The blue screen shows you what errors occured by a numbering system, and if you set your computer not to automatically reboot on system failure, you'll get this info. To do that, go to Control Panel, System, Advanced, Startup and Recovery, Settings, and uncheck the automatically reboot option.

Of course, if you do have 3 fans and they are properly hooked up, and if fan #2 is 0 rpm, there could be quite a problem if that is your cpu fan. So get it checked, for sure.

And when you have set your computer so that you get the BSOD, you write down the error codes, then you push your restart button on the front of the computer to restart it, and then you look up the error codes on the net, as with google - you should get error code sites listed that will tell you what's what.

Could be a software problem, or a ram problem also.

Answer 2

The second fan means that it either has no sensor or there's no fan connected (or it could be dead). The third fan has unusually high rpm at 11 thousand. your hard drive doesn't even spin that fast. Check to see if the fans are all running, but usually PC's have alarms for improper fan speeds and high CPU temperatures.

Your most likely problem is faulty software. If you format and it still does the same thing, then you've isolated the problem to hardware. In which case, I would say it's either RAM, CPU, or MotherBoard. Most of the time, it's the RAM. You can change the bios setting to not restart on hardware errors but that can be dangerous.
