System Boot Failure (.01 sec case LED flash, then off)

Title says all. My specs are a CX430W, AMD FX 4150 (stock speeds/voltages), 8GB Patriot Viper Extreme RAM (stock speeds/voltages), GIGABYTE 78LMT-USB3 motherboard, WD Blue 500GB HDD, and an ASUS HD7770 2GB GPU (again, stock speeds and voltages). This system has run OK-ish through the past 6 or so months. I say this because I've been having to do arseloads of cold resets from the case switches due to god-awful drivers from AMD. I opened her up for some cable management, and as soon as I plugged everything back in and hit Power (to test things), there was no result. This couldn't be from my HDD's coming unplugged (only thing I'd changed), because I'd at least get to BIOS. I flipped the switch on the PSU back and forth, then hit the button again. The front LED lit up for a fraction of a second, then went out. Further button-pushing has yielded no result. I have an old PSU to test with, but that's it, and I am completely lost. The closest I've seen to my problem is http://www.tomshardware.com/forum/302360-31-computer-tu...
this, and it's not very comforting. Please list any tips for what I should do, and ANYTHING that's worked for you in the past.
Thanks, and happy building.

I'd try a better PSU, would look for a minimum of 500 watt w/ 19 AMPs on the 12 volt,

Ok, thanks. A PSU error can arise after months of proper functioning? Also, I have an ULTRA LSP 550W, which I've been told isn't that great, but I will throw it in and see where that gets me.

Well your CX PSU only has 384 Watts on the 12 volt, not sure on the Ultra but should be a lot closer to 500

http://www.coolermaster.outervision.com/PSUEngine says I only need 300 watts, but I'll give it a shot. Interesting to note is that my mouse light up fine, so the PSU produces SOME power.

OMG I DID SOME MORE CABLE MANAGEMENT + REMOVED A DRIVE BAY AND IT WORKS!
Whew! I guess the drive bay was shorting the mobo or putting undue strain on some front panel wires..
Removing it did the trick. Also, my cables are managed loads better now, lol.
