Ok so I ordered a seagate HDD momentus XT 500gb and i would like to know can i use it for my desktop? i believed this hard drive is for laptop. aslo, my new build desktop is mess up so bad, I don't even know what happen to it. if i keep it on they work just fine, but if I shut it down then I can't turn it back on unless I have to shutdown and unplug the power cable. if I don't do that when I turn on the computer they will automatic restart when they get to the part "log in". It happen two day in a row..
