HP Recommended
Operating System: Microsoft Windows 10 (64-bit)

I upgraded my 4530s CPU from 2450m to 2670qm but now the there is a black screen, caps lock blinking 5 times and fan noise. The PC won't start just a black screen the blinking and the fan noise. Whenever i put back the 2450m it starts normally.
