Computer randomly restarts every 10-30 mins

Specs: Windows 7 ultimate
I had my computer crash last year and i replaced the hard drive, video card, and power source added a new OS and everything loaded fine i can surf the web with occasional restart but if i play a game the computer restarts after 10-30 mins. no flicker no black or blue screen just restarts. I ran memory test nothing found, tried a different power supply same issue, wiped and reinstalled the new retail os still restarting. My temps are running 65 while in game and like 50 when idle. i have the case open, no dust is visible, all the fans are working within normal ranges.
I am wondering if i need a new mother board since it is 2-3 years old

Did you check your heatsink for dust? That could cause it. Maybe get a can of compressed air and blow out your computer anyway, you'd be surprised how much dust that removes (make sure there is no power coming into the system when you do this, however).

If that doesn't do it, are you overclocking? If you are, you might want to stop and get a system that's designed for it - lots of gaming systems actually support overclocking because a lot of people in the past were doing it anyway.

Barring that you might in fact want to get a new motherboard for your system, but before shelling out cash there are a few things you want to ask yourself:

1. Do you know how to replace a motherboard yourself? If you don't, that will significantly affect your price for a new motherboard, since you'd have to pay someone to install it for you.

2. If you bought a PC from an OEM, is it still under warranty? Take advantage of it if it is, you could get the motherboard replaced at no cost to you, even if a tech has to do it for you. A computer is probably the 1 electronic device that's worth getting an extended warranty on, the last PC I had before the one I do now I had about 3 motherboards replaced on it which paid for the extra cost of the warranty about twice over.

3. If you've already replaced the hard drive, video card, and power source I'm guessing that's around $300-500 you've already spent on your computer. I can pretty much guarantee you that a new motherboard will start at $250 to replace - and that's if you do it yourself. You can likely double that if you need a tech to do it. At this point it might be cheaper to cut bait and walk away from your current PC and just buy a new one.

4. Keep in mind that a new motherboard - if it works - will likely only give you a certain amount of borrowed time on your current PC. The average lifespan of a computer is about 4-5 years, so expect your PC to remain working for 1-2 years more at most, anything after that is a bonus. Is it worth it to shell out potentially $500 on a new motherboard now and then spend minimum another $500 a couple of years from now on a new PC? That's something you'll have to answer for yourself.

Maybe your BSoD is disabled.
Look here on how to enable and see if it's really a blue screen or a power problem:

That description at least suggests a power problem.
If not the PSU, then maybe the MoBo or the CPU or even GPU.

You can try running a stress-test, to see if the problem is caused by load.
I suggest y-cruncher for the CPU and Furmark for the GPU.
CAREFUL THOUGH when using my suggestions as they will really stress your system. I take no responsibility for damage.

Try starting with your detailed system specs.
Then we can begin. It does not make sense to just continue replacing parts guessing when you should be proceeding logically. We first need to consider overall component compatibility and suitability for your uses. Please include all makes and models of system (if factory built or all components it custom) and all changed or upgraded components.

You have to be a little bit crazy to keep you from going insane.
