Really need help with my computer turning off problem.

The make of ram is Crucial im using 4 sticks of 2gb each.

All the voltages are set to auto, I went back to stock everything when i reset them to defaults.
 
Even at stock you still might need to tweak voltage to be stable,id set qpi/vtt or CPU vtt to atleast 1.35v then test
 
Tryed what you said still shuts down. Not sure what else i can do really. I guess im just going to have to try a new PSU?
 
Problem seems to be getting worse......I just experianced a different crash this time, Instead of the pc just turning off and restarted this time the screen froze with the picture on and i had some loud crackling/noisy sound coming from the speakers. Does that sound like a psu fault?

Let me explain.....Normally the pc just shuts off like the power has come out and it restarts up. This time the screen froze and a loud on going crackly/humming sound comes from the speakers and i had to press the reset button on the case and boot it up again.

Hey mate thought i would update you on this issue....iv upped the voltage on the cpu and the ram to 1.35 like you said and left it for a while and it hasnt shut down so far. Does this definatly mean my psu has become less efficient and even at defaults its no longer sending enough voltage to the cpu/ram?

Should i up it even more since i want to put my overclock to 4ghz back on it. When i did this before i had it at 1.35 also but i don't think that would be enough now. What is a safe voltage to put it up to?
 
What would you suggest then? i don't really want to get a new PSU if i dont need one. Do you think it would probably be a better idea to get a new cpu instead?
 
I had same problem. A new ax850w psu solved it for me.
I later checked my old cm 850w to find it was completely clogged up with dust.
 
Wanted to post an update on this. My pc has been fine since wednsday but yesterday i was browsing the web and the screen froze...power went off on my mamba controll dock and when i pressed reset on my tower it appears bios had reset and all my settings had gone back to default. Any idea if this is the same problem as before and does it give anyone a bettter idea what the issue is?
 
1.35 on both, it was overclocked to 3.2. which is nothing as iv had it up to 4ghz in the past and its been fine even under stress testing.
Its also done it again with the default clock speed. Does this sound like a motherboard issue or most likely my cpu isn't as efficient as it once was.
