Windows 7: PC restarts when it goes to sleep

I would suggest you to take these two tests before doing anything else.

► Stress test the CPU.
Hardware - Stress Test With Prime95
It saves the result as a .txt file in the prime95's folder. Upload the file for us.

► Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest86+ for at least 8 consecutive passes.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Also, Check if the Power Supply Unit (PSU) supplying adequate power to the computer or not.
eXtreme Power Supply Calculator
And let us know the wattage of the installed PSU.

About the change of memory speed, you will not see any difference in the normal activities, but if you work with video rendering or gaming, there might be a bit little performance drop.

I'm running windows 10 home. I had that issue of it resuming at midnight every time I put it to sleep. I found after lots of looking, that it was performing updates at that time. I changed the time and it stopped.
