On the System Restore page you will be taken through a series of steps to choose a restore point (if available) and your PC will then be restored to an earlier point.

If the above software resolutions cannot help solve the error, you may need to perform a couple of tests to check the integrity of your hardware. The first test will be for your hard drive.

Your hard drive will now be scanned for any errors.

If the hard drive is fine, the next step will be to test your RAM. To test your RAM you’ll need to use a tool called memtest86 – this tool can be downloaded online for free at

If any errors come up from memtest86 or from your hard drive scan, you will need to replace the damaged hardware.
