This time however, it's not rebooting on its own and simply stays off.
I did not OC it, the company(AVA-Direct) did. I do not know how to overclock a CPU, but a friend of mine does. I guess resetting the CMOS is probably an idea, but I wouldn't know where to start when going about re-OC'ing this intel chip.
My current power supply is a Corsair TX650 650 watt. About a year old and the PC has never shut down while in use before.
If someone else did the overclocking for you, then that, to me, is all the more reason to suspect that it wasn't done correctly. When it comes to building a computer and overclocking it, I feel that the old saying always applies: "If you want something done right, then you have to do it yourself". To be honest with you, this stuff is actually pretty easy - otherwise I wouldn't have been able to do it (and I'm easily overwhelmed by even the simplest of tasks).
I'd say that the instability is now rearing its ugly head and now it's so unstable that it's not even functioning anymore. If they had done a better job of making sure it was stable, then it would probably still be working right now, but this is the risk anyone takes when they have some outfit overclock their system for them. After all, it's not their computer, so they don't truly care about it. They just do it and say, "Here you go. Enjoy". Plus, 4.0 GHz is no small overclock for the i7-950, so it requires at least a few days of overclocking, testing, failing, tweaking, testing, failing, tweaking, testing, failing, etc. etc. etc.
So I say that you should revert the CPU back to stock and overclock it yourself. Fortunately, you are on Overclock.net, so you are already an expert (because you have access to the combined knowledge of all of the experienced overclockers here). I mean, sure you can have your friend help you, but Overclock.net is always a better place to go to seek help with this stuff.
I imagine one thing everyone will need to know is which motherboard you have, so do you know which one you have? If not, there are ways to find out - some are easier than others, but some ways don't always work.
