New build sometimes post, sometimes doesn't, but eventually always crashes

My first new build gaming computer just isn't working. I've checked all of the suggestions off of this thread: http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems - but I've still got problems.

Issues:
Most of the time when I power it up, it doesn't even post and automatically shuts down.
Sometimes it does launch Windows 7, but after 15 minutes at the most, the system shuts off as if someone's pulled the power cord (no warning, no blue screen, just total power off).

Here's the system:

ASUS M5A97 LE R2.0 AM3+
AMD FX-6100
Patriot Viper Xtreme 4GB (DDR3 1600 MHz)
EVGA GeForce GTX 660 2GB
Western Digital Blue 500GB (7200 RPM, 16MB Cache)
LG 24X DVD Burner
Corsair 430W

Totally new at this and I appreciate any help y'all can give.
Thank you!

Thanks for the quick response.

I've installed a new power supply (Thermaltake TR2 600w) and tried new RAM (PNY DDR3 PC3-10666 4GB). I'm unable to run the memtest because the computer doesn't stay booted up long enough. It's still posting sometimes, but those times are decreasing. More often than not now, it's not even posting, and I'm not even getting into Windows anymore.

Any ideas?

The problem might be a short between the motherboard and case. I had this same problem when I built my last pc. I was afraid I had a bad motherboard or power supply but luckily I tried this- Not sure if you've tried this yet but it's worth a shot if you haven't. Take all the components out of the case and lay them on a piece of plywood or something. Connect all the components like you would in the case and try to turn it on (Assuming your mobo has a power button built in.) When I tried it, the system ran like a charm. My case was the HAF 932. Somehow the reset switch connection to the motherboard was causing the short. All I had to do was unplug the resetsw from the motherboard (would never use it anyway.) I hope this all makes sense. I recommend trying it if you haven't already.

Thanks for the advice but unfortunately it's not a short in the switch. I always hope it's something so simple...

The darn thing isn't even posting anymore. I think I'm going to ship back the motherboard since I've been able to eliminate everything else as the problem (unless it's a short between my ears, that is).
