Homebuilt GIGABYTE GA-G31M-ES2L Hackintosh troubleshoot

[wedgin]

I built my Hackintosh last year and it seems to have subsequently died on me a couple of weeks ago. I blogged the specs when I originally built it below

Now since this was my first computer building project and I'm not really a PC guy I'm kinda at a loss for how to troubleshoot.

 

When the problem first started the computer would boot as far as the initial bios screen, then hang on the memory testing. I hard restarted it a few time and got past it once where it booted into OS X, only to suffer a kernel panic. A few more restarts where the bios would show up, now I get absolute nothing when turning the machine on. The machine does some type of internal beeping, which I don't know where it's coming from, but has done that for awhile. My thinking is that it must have fried something, but I don't have any fallback machine or components to test what might be going wrong.

 

Can someone help me out with troubleshooting this, as I don't even know where to start.
