Upgraded system randomly won't boot past BIOS prompt

I'm totally baffled and had no idea where to put this, sorry if its in the wrong forum.

I recently upgraded my mobo (ASUS M5A97 R2.0), CPU (AMD FX-6300), and RAM (G.SKILL Ripjaws X Series 8GB (2 x 4GB)DDR3 2400). I had a few snags but got everything up and running eventually. After a few days of listening to the loudest stock CPU fan I had ever heard I ordered a Cooler Master Hyper 212 EVO CPU cooler and installed that. Unfortunately I had to take my entire system apart to get to the back of the mobo. After putting it all back together and powering it up, it initially wouldn't boot past the Asus splash screen/BIOS prompt. It went to a black screen after the prompt and then nothing. I opened it up and made sure everything was plugged in and connected properly, but had the same problem when I powered back up. Eventually I pressed the reset button and walked away in frustration, only to come back a few minutes later to find the system booted to WIn7 and running fine. I thought it was weird but I was just happy to be up and running.

Now whenever I have to reset the system it gets stuck on the black screen after the BIOS prompt. Sometimes it takes 2 tries and sometimes it takes 5 or 6, but it always eventually boots up fine. Anyone have any idea whats going on?

The only thing of note is that when I initially powered down to install the new CPU cooler I had to sit through over 100 Windows updates. I let them run and even made sure the system booted safely before powering down again. Not sure if that would have any effect, just wanting to give all the info I can.

ASUS M5A97 R2.0
AMD FX-6300, OC'd to 3.9ghz
8gb G.SKILL Ripjaws X Series DDR3 2400, running at about 1775mhz
GeForce GTX 460
Win7 64
680w PSU

Unstable ram OC. Lower your clocks to 1600mhz. 2400mhz ram is an unfortunate waste/mistake for that platform.

Got it for a good price, and I figured better to have too much than not enough. Thanks for the tip, I'll try it.

Have you tried checking to see if the HDD power/data cables are tight? It could be loose cables.
