HELP! PC won't boot!

[Tyler Sowden]

I've been ad my computer for JUST over a year now and it has ran flawless. It has a i7-5820k, 16gb of ddr4, MSI Xpower x99s motherboard, 1000w psu, 3HDDs, 3 SSDs (it boots off a 1/2 terabyte ssd), and a thx 770 lightning.

Today, I ordered a New 390x to pit in the system, turned it off, went put for a few hours, came back to check on the order, but when I turned the pc on, it wouldn't boot. It freezes late into the bios flash screen. The board has a led post debug number on it the freezes a 66. Please help?

Have you tried clearing the Cmos?

Did that fix it?

Clearing the CMOS itself didnt, But for some reason, when i unplugged all the USB devices, it booted up no prob. Weird but im not questioning it. Thanks for your response tho!
