Fill out your System Specs in User Profile/User CP. I suspect the chipset driver. Someone, if not myself, will link you the correct chipset driver file.
The Safe Mode test caused Windows to bypass loading numerous devices and drivers. This points to one of those devices or drivers as the cause of the problem.
Also, double check Device Manager for splats (not in Safe Mode). Right click Computer, Manage, Device Manager. Identifies drivers not loaded or in error state. DOES NOT necessarily identify a faulty driver.
Now, do your homework and prepare for class. I imagine that you lost a bit of valuable study time.
