I've been trying to troubleshoot some problems with setting up SLI on my PC, and after attempting to clear the CMOS by reseating the battery, the computer won't start up at all. It was working completely fine until the attempted CMOS clear, with the exception that I couldn't get SLI to work properly.

Mobo: ASRock z87 Extreme4
CPU: Intel 4770k
Graphics 1x or 2x MSI gtx 760
PSU: Corsair cx750m

This worked. I got power to the mobo. Should I plug everything back in, or one at a time in a specific order?

Is it possible that you left the jumper on the CLR_CMOS Header after you cleared it, and didnt remove it, as this breaks the mobo circuit and thats how the CMOS Is cleared, by cutting power to the chip, The PC Wont boot without a CMOS. Or atleast to my knowledge.
