i installed my new Z87 extreme 6 mobo today along with my core i5 4670K.

windows gets automatically rebooted when windows 7 logo appears.

i tried booting with 1 stick of ram installed,and also tried changing its slots. i also tried booting without the vga plugged in. still the same. windows repaid says that it cant repair automatically when its done.

it also gets auto restarted when i try to bootin in safe mode after CLASSPNP.sys.

at the moment im with my dvd drive unplugged. What else can i do ? i even tried putting bios settings to default.
