hello, i'm windows 7 (ultimate edition) user today i had a problem with system , desktop suddenly "stucked" with terrible noise from my speakers, mouse pointer and keyboard didn't work, so i couldn't even call task manager:( after reboot everything was ok. what is this problem related to? software (drivers) or hardware? maybe something is wrong with my motherboard ? how can i check system error logs, to find out what caused this problem? thanks in advance and sorry for my English :)

You will see nothing useful in the System event log for this type of error. Windows would not be able to record useful information. If you have recently updated your graphics driver, revert to the previous version.

no i didn't update any of drivers.. i guess it happened when i monitor go to sleep , i was away from keyboard
