New PC shuts down randomly :(

Specs: Windows 7

Hello i found out about this forum by searching for answers to my problem, so im new here!
So, i have this new system [that i built myself (build a PC myself for the first time...) ]

Coolermaster RC-333 midi tower
AMD FX 6300
Gigabyte 7870 OC
Gigabyte 970A-UD3
Corsair Builder 600W builder series v2 80+ bronze
CORSAIR VENGEANCE DDR3 2X4GB 1600MHZ C9

Ive been running it for 2 weeks with no problems (i must mention that im a noob and built it myself), and one day i saw in some forums how to oveclock your GPU a little from AMD Overdrive in Catalyst CC settings. So i put a higher setting which was 1150 in clock speed and 20% in power. Then i saw some FPS malfunction, low from high, and then high again. So i restored the DEFAULTS in amd overdrive, even restarted my PC and then disabled AMD overdrive. Then the videogame worked perfectly again. But after 40 minutes my pc shut down. And it is the first time it does that! Then it wouldnt turn on. So i turned the PSU power off and turned it on again and the PC turned on. And today my PC shut down once more while i was surfing the web! With no applications open! Only Chrome... And im pretty sure the temperatures are allright. Please what should i do? :(

I think that it might be a lose connection to the power
make sure that all of the connections are pushed in correctly.

Install HWMonitor and report all temperatures, voltages, and fan speeds. We are concerned with the numbers at idle and after gaming for a while so leave it open and play for 10 minutes and then give us the minimum and maximum values where the largest changes may be the best clue.
This information should point us towards the best line to investigate so it won't be all guessing. After that, we may ask you some specific questions or to do some specific tests.
The more details on the problem that you can give us, the better we can narrow the possibilities down.

If I'm reading you correctly you made your changes from within Windows itself.

I wonder if it would be worth doing a system restore back to before you made this change, just in case some setting got stuck somewhere. It "seems" that your troubles started after this change (although it could be just coincidence).

Always pop back and let us know the outcome - thanks

You are a bit hot on your CPU at 58C where I find a max listed as 61C.
You may want to remove your heat sink (CPU), clean it off, and reapply the correct amount of thermal compound. On AMD processors I believe you need to place one small dot amount the size of a grain of rice in the center of the CPU surface, but here are the full details:

Also your only listed fan speed it very high. If that is the CPU fan, I guess it is trying unsuccessfully trying to cool it off. Do you have case fan(s)? How Many? What orientation? Are they plugged into your motherboard? Where? Is the CPU fan plugged into the CPU fan port or another one? Does it have a 4pin plug or 3 pin?

1.If that is the CPU fan, - Yes its the CPU fan i guess
2.Do you have case fan(s)? How Many? - Yes one only on the back right under the PSU
3. Are they plugged into your motherboard? - I plugged it in the PSU
4. Is the CPU fan plugged into the CPU fan port or another one? - I plugged in a slot that says CPU_FAN
5. Does it have a 4pin plug or 3 pin? - 4 pin
6.where I find a max listed as 61C. - I think this is the maximum temperature it reached in the current section... cuz now Max temp is 38 !

Assuming your one rear fan is exhaust, that is fine.
I prefer case fans be plugged into the motherboard so that the fan speed is regulated by your BIOS and is dependent on the temperatures.
Your CPU peak temperature shown on your post after 10 minutes gaming is very close to the listed maximum. At that maximum the system will shut down to protect the CPU and before that, it will probably throttle back to try to cool it.
The most likely scenario is that the heat sink was not properly attache to the CPU, unless you are running an elevated VCore (CPU Voltage). My recommendation is to reset the heat sink after cleaning both surfaces, using newly applied thermal compound. Please look at the link I gave you above for the proper procedure. Then, if you might have made any changes to your CPU or other voltages, reset defaults in your BIOS and start over again making sure CPU, Memory, Hard drive/boot order, etc. settings are correct.
