Got so pissed by the hard drive of this pc. After got it for only 4 days the m2 hard drive just broke down for no reason, it doesn't show up on the computer and the Windows system just crash every time I started the computer. After unplug and replace the original hard drive with a new ssd drive I got from somewhere else and reinstall the Windows system, everything went back to normal. But overtime when I tried to plug the original drive back to the motherboard, the pc just turned blue screen again. The m2 drive just wasted for no reason and I have to pay extra money to get an extra hard drive.
