The video adapter & cpu may be overheating. Have you monitored cpu temperature? If not, google search cpu temperature freeware to do this.

Cpu temperature and conditions are good. But Graphic card is nvidia. But it's not showing in the device manager(only intel graphics driver is there, when i install nvidia driver it's saying ther is no driver) And graphics card is overheating

Only the 576G should have the separate GPU. If you have the G model and GPU is overheating, it's being detected by the temp monitor. Do you have a screenshot of the temp monitor?
