1. Click on the Windows logo button to show the Start menu. Type 'system restore' into the search box at the bottom of the menu, then press 'Enter' to open the 'System Restore' utility.
2. Click the radio button next to 'Choose a different restore point,' then click the 'Next' button. If you don't see this option, then click the 'Next' button to proceed to the next page.

3. Read the date, time and description for the listed restore points. Figure out when the fatal system error started. If you don't know or can't remember, it's okay to guess.
4. Click to highlight your chosen restore point then click 'Next.'
5. Click the 'Finish' button on the 'Confirm your restore point' page. Wait while Windows automatically restores your operating system and files. After the computer restarts, a pop-up message will show on the screen stating whether the system restore was successful. If it was, future fatal system errors should no longer occur, because the problem has been repaired.
