My laptop (Acer) just STOPPED working after few times using it. When I try to boot it up, it just says Realtek PCIe GBE Family Controller Series v2.46
PXE-E61 Media test failure, check cable

PXE-MOF exiting PXE ROM

and then it just says

Operation system not found

....and it repeats this forever
