If it fails to pass all the phases of the Memtest scanning process, then your blue screen registry error 51 is due to the bad/corrupt memory. Then there is no option to fix the bad memory sectors other than by replacing the RAM.
Method 5: By Updating your Drivers
Every program on your PC works primarily because of the Drivers. The Blue Screen Registry error 51 may also occur due to malfunctioning of your Driver or may be it has become corrupt. So, it is very important to keep on updating your Drivers regularly.
It is but obvious that you cannot check and download for each and every single driver. There are tools which contain driver update for important system programs. It will automatically scan and update for the various drivers if needed.
I would suggest you the Driver Agent Plus tool which will automatically update all your drivers.
I have set up a direct downloading link for the full version of this Software tool.
