Ok, so my computer has been doing this for a while...well not the ram thing, but every so often while I'm playing a game(or really it could just decide to crash randomly, it's just more common while I'm playing games), for example, I could be watching you tube, or be online, and it may shut down, I really have no clue why it does it, but just recently, I realized that when my computer crashes, then re-boots itself, only 4 GB of my 8 GB of ram is being utilized. However, It's only when it re-boots that the ram isn't fully available, other wise if I turn the computer off then turn it back on, the full 8 gigs are there.
I won't lie, i'm not the most tech savvy person...Id like to be, but I'm just not there yet, anyway, I've scoured the internet for similar cases, but i just can't seem to word my problem correctly, most people have 2 stick of 4GB ram and the solution is one of their dimms are bad...but i'm only using the 1 8GB dimm soooo...it's not a faulty dimm otherwise my computer should'nt boot up...right? I've tried many things so far, to try and at least determine why my computer crashes. While attempting to find a case, that is similar to mine, i found the program called: whocrashed which told me something about crash dumps being enabled but the computer could not write the crashes. anyway, that pointed towards a problem with ram (or so I believe), but I'm somewhat in denial about any of my hardware being bad because...well...you know as mentioned previously the PC should'nt boot if the Ram stick is bad. Computer parts can be very expensive, so i'm desperately hoping it's not a problem with the actual card. I am in desperate need of help, if you need anything else than what I've told you, i'll try to respond back with the answers as soon as possible.

Info you may need:
-I have 1 stick of 8GB(RAM)
-I have a gtx 750, if that could be a reason for the crashing
-my power supply is rated for 330 watts but I've done the math, my system should only use around 250 watts including the gpu
-and my processor is an AMD A10-6800K with a clock speed of 4.1Ghz
-and I have windows 7 ultimate installed for the OS

also as far as cooling, the temps seem to be fine, I don't see any dangerous temps at any point while the PC is in operation (CPU stays around 35 C and gpu stays around 30 while in idle, which has been known to crash as well, so i'm pretty sure it's not a cooling problem, also the PSU isn't getting hot or anything while the computer crashes.), however if it helps, i'm using the stock coolers for both the gpu and the cpu, and i have 2 case fans, one in the front, and one in the back.

---All help is appreciated, at this point I'm just dumb founded, as to why it's crashing.

-Oh and iv'e also updated all of the drivers, suspecting that was the problem...it did not help...SOS

Update #2 It's been 6 days now, and in said time, I've done a fair amount of research, I've narrowed down my problem, to the PSU or the motherboard...
At this point i'm just writing this to help anyone else out there, should they have a similar problem..

The symptoms matched up with a bad psu, nearly to the T. The reason being, or at least allegedly, the graphics card i was using needs at least 400 watts minimum...which is odd because it was working just fine, anyway i found that the graphics card was not the issue when i switched back to the on board graphics...this showed no improvement, thus showing that either the psu or the graphics card is not the issue...well the psu could be an issue because the gpu needs 400 watts, but as far...

Update #1 As of this update it's been about 3 days of me going nuts over this issue.

Steps iv'e done thus-far for trouble shooting the problem:
-1. I've ruled out the GPU being an issue, by removing it, and running off of the integrated graphics, no improvement what so ever, crashed just the same.

-2. I believe the physical RAM is not the issue, after running memtest86, no errors were found, and upon closer inspection of the inside of my computer, the components are not physically busted, corroaded, or in anyway not connected

-3. The motherboard ram slots ( the whole 2 of them!) seem to be in working order...or both of them are broken, either way the problem still presists, upon switching the channel my RAM stick is placed in.(the first time I switched the RAM slot, there seemed to be an improvement, I was able to play games such as fallout 4 without crashing, but upon re-booting, the problem continued, and i could barely start the game without the computer crashing.)

-4. So upon ruling out the:
1.RAM
2.Motherboard
3.Cooling/Temps
4.Graphics card
I'm left with the cpu and the psu,
I highly doubt it's the cpu, because...well, it's another case of denial due to my limited budget, but also nothing i've looked up thus far regards a problem with the cpu, that and im pretty sure (I'm no expert but,...) the CPU having an error would cause more than a simple crash here and there...

A friend from work says, he actually had a similar case to mine, which I find to be slightly hard to believe given the complexity, of my problem, but sure enough he said his computer was crashing and would reboot with half of the available ram. His solution was to buy a new PSU with 1000 watts...Seems a bit overkill, but too each his own, none the less, he says this fixed his problem entirely. I really don't know, does this seem plausible? i don't know much about PSU's given they're ... not really part of the "computing" experience aside from allowing the components to be on.

On a side not i've realized upon further examination that when the pc boots after crashing and the ram is cut in half like it is, half of the ram, I.E. 4 GB is "said" to be allocated for hardware...No clue what that means...other than it's obvious name, but what hardware could the ram be, dedicated too but the cpu it's self?

At this point anyone who reads this is a saint for even looking this deep into a strangers problem, but i would deeply appreciate a response, even if it is just to say, "wow...this guy types a lot!"

after having exhausted most options, i'm left with a motherboard problem, probably caused when i was cleaning out my system, of dust and webs...

I hope that this will help someone, at some point, it certainty would have been nice, if this was around, when i needed help.
