So I have this MBP in my signature. Its been running kinda slow since it got it. I know its a C2D but I run a similar chip at my work computer in a Mac Pro that doesn't feel as slow as this. It takes a while to open PS files that arent that large and sometimes its a bit choppy at scrolling or responding. anyway so its opening a PS file and it basically stops responding, keys finder cursor everything, next thing i know its i get a blue screen as if the computer is restarting and it takes me to the login window, but the computer didn't restart, no logo screen or chime. Any clues?
