I am so sorry for the long post but please PLEASE help me I do not know what to do at this point. I already cried over this.

So basically my PC started restarting first of all, out of no where. It didn't start roaring or get louder but all of a sudden i'd find that it would randomly shut off even though its generally clean. I use the MX-4 thermal compound and this was still fresh even after looking at the CPU today. It would first shut off on games but then it would end up doing it anytime what so ever. There would be also sometimes complete screen freezes, blue screens, whatever you can think of really. I believed it was the faulty PSU. Quite frankly very certain of it because I've brought a keyboard and a mouse and felt like it would be pulling more wattage than before. So I made my way to get just any PSU at this point because I could not get it sent to me as it would take too long. I had some unknown brand's 450W and then upgraded to 750W Evga GQ.

As I hoped for, it has actually started working fine. It was not loud or anything, so I do not believe the CPU was overheating at those stages. It was fine from the 25th May to 4th of June, yesterday, when suddenly, in game, I got blue screen, lines all over, blurred screen/half screens/quarter screens just everything screens that could happen to screens. So I was like 'kay, looks like graphic card let's try to take out the Radeon HD 6700 and try and use my sister's previous GPU, the GTX 460 and see if it works.

Let me also note in the end that the pc monitor didn't even detect video with the Radeon thereafter and that I also applied the compound to the GPU's processor as I was replacing the PSU. The previous compound was actually scattered around the black area with the gpu's processor at its center, which is weird because I did not have this kind of problem with the CPU I always made sure to just put that little dot. I cleaned it with acetone but some bits were still around the GPU's little silver blocks in the black area surrounding the gpu's processor. I think that it could of been due to the left over compound that my card went but it is at least suspicious that it was fine until yesterday, and went quite after I changed my PSU.

Now, I put the GTX 460 in. Its fine for like one 10minute game. Then, when I come back after a while, my PC shuts off shortly after starting a game. Then again after restart just after loggin in besically. I strip the cpu, which I haven't touched for the whole above process, after I inspected the CPU increasing to the temperature of 53 degrees while gaming when PC shuts down. The compound is not over spilled in this case but I do reapply without spreading. After watching multiple videos on the amount of compound it doesn't look too little or too much.

I try it out. I have started up same game and now my cpu goes all the way to 56 degrees, without shutting down for about 1/2h, but of course the overheating is still an issue. I noticed also it gets roars out around that temperature, above 50 it starts to roar, then calms down, goes to 47 but then up again and it could even reach 56 before going down again. It's max 36 degrees at startup and just oscillates when in windows. I saw like 18 degrees, but mostly in windows its about 27 degrees I believe. Now its mostly at 50 degrees during gameplay. It's really upsetting because I actually wanted to upgrade to 750Ti.

My case is so so standard and i got one fan on cpu, gpu and back of the case. Classic fan size. I understand that a lot of overheating attributes to bad air flow but basically I am really unsure that is true because temperatures were like the same when the case is closed and with both sides of the case actually open. If it was caused by bad flow in the case, the heat getting trapped, it still wouldn't go up that high with the case opened up. It was hot today so like about 21-23 degrees in the room right now, but I have never felt this much heat from PC before applying the GTX 460 card, or this much sound. Also these are the stats for the two graphic cards http://gpuboss.com/gpus/Radeon-HD-66...eForce-GTX-460 and it just doesn't feel right that such a difference could be attributed to such a small upgrade. Especially since both the radeon and the gtx have fan in the exact same place, so air would flow the same as with the radeon card.

As much as I just want to upgrade the case to a better cooling one, I don't want to do so without being certain of what is actually going on. I also honestly feel like it may be my motherboard. Because if it is that then even if I buy all that cooling, my temps would still be high. Please also note that the cpu's heatsink is the hot stuff. Very hot stuff. The air around it is not so much. And the GPU is totally cool.

The PC was acquired 2011/2012.

Stats of my other stuff:
CPU: AMD FX-8120
Motherboard: M5A87
An older version of this case: https://www.google.co.uk/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwiL_oC-uJLNAhWrKsAKHXMUC6IQjRwIBw&url=https%3A%2F%2Fwww.pcspecialist.co.uk%2Fpc-images%2F2935%2F&psig=AFQjCNFhS5sDmYaYyBJDgSI0f0p79V0mPA&ust=1465269514000110

It looks like this is also the MSI version of the GTX 460 code GF104..?

I checked https://pcpartpicker.com/list/#incompatibilities for compatibility and it seems fine with those components.

AGAIN I am SO SORRY for the long post but I just want to give as much information as possible to get any help/ ideas whatsoever!!
 
Solution
Temp looks fine, check it with amd overdrive and prime95 with smallfft
Uninstall amd drivers with ddu uninstaller
Run 3dmark basic edition (firestrike) and post the link which comes up at the end
Run furmark and post temp after 10minutes
Install Memtest86+ on an USB flash drive and boot from it
Check hdd with manufacturer's tool
Update motherboard's bios in bios itself
All pcie power connectors plugged into the gpu?

Those temperature are well below (I mean WELL BELOW) the point at which you should start worrying. Not anything about temperatures. Sounds like a motherboard problem to me. Record the blue screen error message and search it up to see if you can find anything relevant. For this, anything is on the table from bad mobo, bad connection between GPU and mobo, or PSU delivering unclean power. Look up the blue screen msg.
