Hi as requested i started my own thread. one day, i opened my comp, and did my usual things, chat, internet (facebok) that's all. then crash, blue screen. I get a blue screen having the message Stop 0x007f Everytime i restart, same thing. after completing on line where the windows loading logo comes out, blue screen I've ran memtest and left it overnight with a total of 25 passes, no errors. I've uploaded a windbg output and a hijackthis file as requested. Tnx.
