Can i test if the psu is affecting stability in my new build?

Hi this is my first computer build, and I tried to put most of the money into the graphics card and the cpu. That being said, my system isn't giving the gaming performance I expected. I ran skyrim at a good fps on medium-high with seemingly no trouble, but then it randomly crashes. I suspect the psu is the problem and I am wondering if there is any way i can test this. Thanks for any help in advance. I really appreciate it.

Here are the specs:
AMD Athlon X4 740 Trinity 3.2GHz

gtx 650


MSI FM2-A55M-E33

Hard drive:
Western Digital Blue 1TB 7200 RPM 64MB Cache 6.0Gb/s

8gb but Im currently only using 32 bit

optical drive:
DVD burner

What confuses me is that 500 watts should be way over my needs. Could it be the Windows Vista 32 bit operating system? Or is this system just not as strong as I thought. Recommendations for replacement parts would be really helpful. I think intel would have been the better option, but I figured amd would be strong enough for a gtx 650.

I would graph monitor your voltage + or - 10% is the way to judge it.
I use speedfan for that.

There's only one way for folks like us to test hardware. Replace it with something known to be good.

Thanks for all your responses. So I tried a different psu and it still gave me problems. Then I tried upgrading the operating system. I thought I was installing windows 7 64 bit but I installed windows 7 32bit. It turns out that the problem was windows vista. Even without 64 bit I can now max out skyrim with screen resolution and max settings. I will never use vista again. Thanks again for all your help.

Anonymous, I'm not really sure what you mean. Can you show me a program that does this? What would I look for in a good psu?
