before followiung any steps check this step out.
Do as the first few posts suggested and turn off auto restart on system crash.
this will probebly give you a BSOD when shutting down isntead of it restarting, dont be startled as this is the main issue we have.
get the STOP CODE
Or just copy the whole bottom line of the BSOD>
then type the STOPCODE 0x0********
into google and it will give you sum results about this crash. also at the top it might say which issue it has, possible a
Is common. but tell us the STOP CODE and the BSOD message on the second row down. this will help to solve the issue. but for now. as it restarts. go into safemode and try shutting down then. this could be a advanced driver crashing.
if it still restarts. we have a problem, but also if you have a year warrenty, TAKE IT BACK. say it WONT shut down.
If it will shut down there. it is probebly a keyboard or USB device.
Remove all USB devices in normal windows then shutdown with the mouse plugged in. and then one at a time try pluggin gthem back in, with my computer a USB router connection causes mine to restart on shutdown.
hope i've helped.
It is most likely either, BSOD due to Hardware Driver issue which can be solved.
USB Device (most likely, Router, printer (still turned on) keyboard and mouse.)
also, if it is a USB device. try unpluggin it before shutting down or reinstalling the driver, if its a printer, turn the printer off before shutting down as you should anyhow to save electric.
but if its a BSOD, tell us it and we can identify it.
