First! Welcome to Asus ROG forum!
If install some game in safe mod fix the issue I would concider re-installing windows. Backup everything and resetthe laptop to factory default then re-install. If my memory is good the G51J factory reset step are the following
1: Back up EVERYTHING you might need on a external device
2: Power off
3: Tap F9 and power on. Tap F9 until you see the restor screen appear
4: follow the instruction that will put everything back like the first time you opened it.
5: Once everything will be done, open the laptop and the windows install will start over like the first time you took it out of the box.
6: Install software 1 by 1 not a bunch at the same time. If issue still persist, then I would start component troubleshoot
😉Keep us up to date!
