Another method is through the "DXDIAG Test" 

This is to completely check if your computer works perfectly fine.

(Ideal system check for working at home)

1. Click Start on your PC
2. Search and click Run 
3. Type DXDIAG > Enter
4. Go through each tab on that dxdiag window by clicking "Next Page..."
5. Click "Save all information..."
6. Save the test results (in notepad) to your Desktop
