Random BSODs and freezes in windows 8

Ok, so the other day my 1-year old daughter snuck inside the computer room and spent a minute or so turning my desktop computer on and off repeatedly. I didn't use the computer untill today and within a couple of minutes or so playing Battlefield 4 it froze. Later it also froze while web browsing using chrome and also during boot up. I've also had a couple of BSODs (system service exception, and something with a reference to an address 0x0000001, which I can remember). I've had problems with the ram before on another computer so I tried running Memtest86+ with all four memory sticks installed and it soon resulted in the error in picture. I then tried playing BF4 again with only two of the sticks installed untill it froze, and then switching the sticks untill it froze again. I also tried running Memtest with only 2 sticks installed but I'm not able to reproduce the error.

There is most certainly a problem with the RAM, but could there also be a problem with other hardware?

Hey,

Two things.

I would make sure that the bios is set to Optimized Defaults then save.

I would also unplug the machine from the wall for a minute or so at least, then test again.

I'm not sure where to change the bios to 'optimized defaults', but I will have a look. Could it be that the BIOS-settings changed due to the rebooting?
 
Is there even a chance of ruining the ram from turning the computer on/off repeatedly? I guess it would put more stress on the mechanical parts inside the computer such as the HHDs spinning up/down or even the fans, but could it also cause voltage spikes or such capable of destroying the ram? So far all of the ram modules seem to have problems. I tried running BF4 with only two of the 4 memory cards, which shortly caused a freeze and reboot. I then switched to the other two sticks and tried again with same results. I will try them one at a time in case only one in each pair was faulty. (Each stick is 4GB).

I also tried running the computer with 2 (2GB) sticks of some older ram I had lying around, which didn't seem to cause any freeze while playing BF4. Haven't tried Memtest86 on those.
 
Ok, so I haven't had much time to circle in the problem lately, but I tried testing the ram using memtest86 a little more thorough. Basically I ran all the sticks individually in the same slot for approximately 10 hours / 10 passes without no errors, which makes me think the ram modules are fine. I then tried running one of the modules in all the slots for approximately 10 hours / 10 passes with no errors. That makes me think both the ram and the slots are fine. I also tried running two modules at the time with no errors in memtest86. When all these tests passed I started using the computer as normal, but with only two modules installed with still made the computer crash occationally. However, when I use only one module (4GB) it seems relatively stable, and I haven't had any problems that I can think of.

What could the problem be?
 
You can attach latest crash dump, just for good measure (so I can glance over and double-check to ensure nothing stands out) - but it is likely still defective memory.

I would just RMA the memory and call it a day. When it's all fixed, you'll be glad. (Make sure modules are actually compatible with motherboard, too.)

I will contact the company where I purchased them, however I'm pretty sure they will charge me for testing them if they turn out to be fine. But is it likely that the RAM turns sour just from switching the computer on/off a a number of times?

No, not very likely, but obviously there is an issue and it has to be something. heh

Memtest above shows something.

I just noticed/realized that I haven't looked over the software. We can check it:

Yesterday I tried installing all memory modules and instead of running at 1600MHz, which earlier have caused BSOD within short time of playing, I tried running at 1333MHz and no problems occured. I'm not 100% sure this wan't by coincidence, but I will be testing a little more this weekend. I contacted the guys I purchased the modules from and I will send them back early next week.

A short question: How big is the difference between running 16Gb ram at 1333MHz compared to 4Gb at 1600MHz? When I ran only one module it rarely caused problems.
