Computer freezes while watching movie

[Froddo]

Hi opened a thread with the same title thinking it was my graphics card that was the problem. I found a software that maxes out my Graphics cards fan. since then the temps are perfect. I was watching a movie while the stat were showing in corner to keep an eye on temp and fps. It suddenly crashed with a ere deafening sound like high pitched static. Its said the temp of my GPU was 31C and my cpu temp was 19c so what could be the problem?

I have cleaned out both heatsinks with a very soft paintbrush and added fresh thermal paste.

Windows 7 premium
AMD FX 4350 quade core 4.20GHz
Asrock 970 pro atx motherboard
EVGA GeForce GTX 670 4GB Superclocked+ w/Backplate
3x HDD 250GB/500G/1TB

My windows is up to date also my Bios for my board is updated along with drivers.

Realy need the help on this. Any suggestions?

What make/model power supply are you using?

It is a 750Watt PSU not sure about the make of it.

Usually if you don't know, it is the culprit

Ok its a
CORSAIR CX750 Fixed ATX PSU - 750 W

The Corsair should be okay. Do you know how old it is?

I have only had it for 2 months before then the problem was the same so it cant be the PSU.

Are you overclocking anything (CPU, GPU, memory)? If so, reset to stock speeds and try again.

No i never overclock anythink as i know the risks involved. everythiink is stock. But what i can tell you is that i was playing madmax in 1920x1080 res and it crashed after 15mins of gameplay. I even had the side of my tower open for ventilation and found my GPU was very loud and very hot. Im assuming its a failing GPU and has purchased a 4GB Gigabyte GTX 960 WINDFORCE 2X. Once its been delivered and setup i will let you know if its solved the problem.

After playing games all day using highest settings its happens again this time with brand new GPU as described above. the odd part is that this happened on an old game battlefield 3 on max settings. so what is the issue and why is this still happening?

Have you tested your memory with memtest (http://www.memtest.org/)?

These sorts of issues can be caused by defective memory, a faulty CPU, or even a motherboard problem.

Start with testing your memory.

I have done memtest over night and got 11 passes with no errors. also done HHD tests and they all passed no errors. all temps are low so no i have purchased a new PSU as i suspect faulty PSU. I found that if you type even viewer in the control panel you can see all errors. I found critical errors saying kernal-power this means The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. LOSS OF POWER! so this is the PSU fault right? I dont have any spare PSU around so i have purchased an upgrade from 780 to 850 watts. Mabey its because it the load since im running 3x HDD and 4GB 960 GTX. So RAM passed HDD passed GPU passed so it comes down to 2 things PSU or motherboard.
