just made another think that i thinked off, usually compiuter crashes when i give two tasks one after another (short time between tasks. for example start task manager and swich fire fox tabs) so i tried speccialy crash compiuter whilist running scan. lol, i could not crash it, opened like 3 youtube tabs, all running, giving alot of tasks, more then ussualy... probably the solution is to run hardware scans at all time i am runing compiuter, lol, just kidding.. but that wos not expected, any ideas?
