If you have no idea what "Driver Display shuts down and recovers", you shouldn't even try to give advice.
Gordon advised you to start your own thread, as have I.
You are way off topic on this thread, and this only confuses things, and makes the suggestions for
your issue unavailable for others with the same problem should the do a search for
'Driver Display shuts down and recovers' or similar.
The topic of this thread is if Registry Cleaners are safe or beneficial. not TDR, BSOD or similar issues.
When you do start your own thread try and avoid typing a wall of text. It's hard to keep track of
different points when everything is mashed together in one big block.

"I first installed 16 GB (4x4GB) Kingston RAM which failed its MEMTEST immediately. A few months later, I installed a different Corsair 16 GB RAM set. The Corsair set failed after 6 months. I now have another Corsair 16 GB set, XMS3, and it has been working OK for 2 years."
Wow - that's a streak of bad luck, or bad overclocking/overvolting. I've never had a bad RAM.
Not to say that it does not go bad on occasions, just that your situation would be uncommon.
