I have a hp 450 model laptop, with wimdows 7 64 bit with 4gb ram and intel i3-2350M cpu @ 2.30 GHz.

Recently I had to change its motherboard with another original motherboard.

But a problem arose that is its screen goes black for a second then comes back and it makes sound similar to when you eject or insert a USB device.
I am not a regular computer user so please help me understand what may be wrong.

Thanks
