I have had my computer for almost 1 year.  During that time, I probably had 2 or 3 BSOD.  I upgraded to Windows 10 after being provided with their free upgrade.  The BSOD began to occur once or twice per day immediately after upgrading.  After a few more days passed, the BSOD began to occur more frequently.  This could be anywhere from 2 to 11 times in a day.  Since this was the only change made to my computer, I thought that it was the likely cause.  I wiped my HD and reverted back to Windows 7 (owned copy).  This failed to fix the problem.  I have tried to resolve this issue on multiple product and technical forums without success.  However, everyone has felt that the problem is resulting from a driver issue.  I am not certain anymore.  I am beginning to think that this is a hardware problem.  I have changed to another HD, removed the video card and plugged directly into the motherboard, changed DVD drives and changed memory.  None of the changes worked.  This leaves motherboard, CPU and PSU as possible problems.  I will supply computer specs and the accumulated crash data if people think they can help.  My main reason for visiting the forum is to ask if there is a test or software which I could run to determine if the PSU is working properly.  I am using the EVGA Supernova 750 B2.   

What error codes are appearing in your Event Viewer or in the BSOD? Please give us a complete list of the components in your build including the manufacturer. 

I would say you have a bad memory module from those Memtest results. If a ram stick gives you errors put it aside and test another. RAM can be finicky at times. I ran Memtest all night for each of my four sticks and they all passed. After I installed them all at the same time they failed. Tested again and all was fine until I placed all four sticks in again. On the third day the bad stick finally showed up and gave me errors. I removed it and applied for an RMA replacement and it has been fine ever since.

Does anyone think it could be the motherboard (slot) instead of the memory stick?  Why do you think CPU is a possibility and can it be tested?

I agree that it is likely a CPU or motherboard issue. You already tried replacing the memory; that's why I didn't include memory as a likely culprit. Honestly, I would think that a failed CPU memory controller is the most likely cause since physical damage to the memory socket or CPU socket is unlikely to happen out of nowhere without any changes being made.

Does it make sense for a computer to boot and run for a time with a bad memory stick?  Someone suggested that a bad stick would prevent the computer from running at all.  I'm trying to ascertain if the problem truly is just a bad memory stick and not the motherboard.

A computer can run with a bad memory stick. The bad stick will cause blue screens, freezes & random rebooting.

I have now used my computer with a single memory stick for 4-5 days (not continuous operation) without crashing.  Throughout the process, I was hesitant to view this as a memory issue because either I have been very unlucky (I've had 4 sets of memory sticks with seemingly one failing in each set) or something corrupts the memory sticks.  Nevertheless, my computer seems to be working now.  I currently have 4 memory sticks available for testing.  One seeming to be clearly bad, one working, and 2 brand new which are untested.  I'll try my computer with each of the new sticks individually and then I guess the problem can be deemed "resolved."  Thank you for all of the assistance provided thus far.

I had all of the same BSOD's and a few more for over  a year. This made it very difficult to play certain games like COD titles up to AW; the odd thing is I was able to play Mad Max rel (2015) all the way to the end.  My PC would BSOD idle or while doing anything you can imagine it was always random. The more BSOD's that happend the more corrupted my OS install got; I tried to format and reinstall windows but the process would fail every time. Now it takes this system over 15mins from Windows boot logo to completely load my desktop environment. The other thing is no matter what version even the XT one I could never fully sync the Bitcoin core block chain I would get no closer that 1yr 23weeks before a BSOD. Every time this failed my block chain db would corrupt and have to re index but still fail in the end. Now I am waiting to get a larger SSD drive and then I will start from a fresh install. I finally got off my lazy streak and ran memtest on each module one at a time; no issues until the last stick was tested it failed right at 15secs of loading test with over 22k errors and  counting. I removed faulty module and down to 24GB ram but no BSOD in 3 months no matter what I do on my PC; from programming, extreme browsing, file manipulations and transfers to gaming. So the memtest is is defiantly worth performing; the process took about 48 mins per pass on each 8GB of ram module except for the failing module it took less than a minute. More good news after bad module was removed I was able to sync Bitcoin block chain on first attempt.
 

Glad your issue is now solved.
