My computer is crashing!?

[Moderation_1]

Thank you in advance.

Starting at the beginning. Two months ago my computer started having "Display driver stopped responding" error and died, whenever i would watch a video, or play a game.
Tried EVERYTHING software wise to fix it and i did not ever fix the problem. Two weeks of the GPU doing this and it then died, and would not display any image on the screen so i threw it out. ( GTX 680)

A week later, i then bought a GTX 780 Ti.
Installed it, used DDU (Driver uninstaller) to removed GTX 680 drivers, and installed 780 Ti drivers.
Seemed to work great, no device driver stopped responding.. i fixed it.

Started a GAME up and 5 minutes into the game my screen goes black, with the sound looping for a few seconds, then a windows error pop up box sound. Screen is still black after 5 minutes and GPU fans are forced to 100% the instant the crash happens. Forced to restart computer.

Reseated GPU, made sure everything was plugged in correct and it was.
waited two days, still crashes. Checked CPU temp... on IDLE it was running at 80c
NO idea how long this was happening, figured my h80i pump died. Threw it out.

Went and bought a heatsink, installed it and CPU is back to normal temps.
While installing.. learned that my CPU_FAN 4 pins on my MOBO is dead. So my H80i might not have been dead at all, it was the pins.

Ram is new
New PSU, 1250W

Still crashes of 24hr normal use without running games or stressing systems.

What the hell is wrong? i've spent so much money already!

(GA-Z77X-D3H)
8gb Ram
780 TI
i7 2600k
1250W PSU

Just an UPDATE
/
I've just stress tested GPU for 5 min
100% load, temp max 70C with aircon on top of it.

Stress tested CPU for 5 min 100% load
90C i let it go upto with aircon on top of it.

NO CRASH

I will run game and monitor temps.
If it crashes then, while under those above temps.. im at a loss.

Update 2-
Ran a game, From the Depths for 5 min.

Upon doing anything more than just standing there the screen went black. Sound buzzed for a second and then resumed normal game sound.

COMPUTER DID NOT CRASH because the game was still playing, the GPU fans sped to 100%
Gpu temps as well as CPU temps were in 40-50c when crash.
GPU is not overclocked.
CPU is overclocked to 3.5Ghz

I've got old 780ti drivers installed because i figured new ones may have been casuing this. I will update to new drivers now and test again.

Update 3-
Lowered MEM clock by 300 on gpu and core clock by 100
Updated to newest drivers
Still crashing.

Doing a fresh install of windows.

lol 1250w psu talk about overkill. If a fresh install of windows doesn't fix the problem then it is most likely a hardware issue. There are some other possibilities though like certain programs causing an issue or maybe you should just use Driver Booster to update everything. Also windows might need to be updated. If none of that works then there's something internal going on there.

Just trying to get the pc to detect my other drives.. stopped detecting them yesterday.. just smelt a burning plastic smell from pc as well, suspect a fan motor burnt out because front one stopped spinning. Today is not my day. Mobo could be on the way out i think, doesnt want to detect more than 1 hardrive, CPU_FAN pins not working ether. Will reply here after tried everything i can think of.

ooh that sounds bad. You see when you get new parts its always best to upgrade everything else along with them. Good luck with that.
