The drop is not that high, only a few inches. Dropped it to the topside of my pc case. Now everytime i try to boot up it always lags when loading the windows. Its lags and then restarted, When i dropped it. The pc was on, and then starts to lagg and freeze and then i restarted it. And it running okay but soon after the day after it happened it wont boot up. So i try to realign the RAM placement and it works a few hours ago. But now when i try to boot it up again, i cant even reach windows dekstop. Anything i should check ?
