"No input detected" on monitor new build

Hey guys, new poster here but have been reading this so much lately I feel like I know some of you already. So here's my problem; my monitor won't detect that my computer is hooked up, so I can't start installing stuff and getting it on its feet.

I'm new at this, but over the past few weeks I have done a lot of research, talked a lot with my friend about computers, and I felt like I could build a PC. I mainly wanted it for programming as I am majoring in computer science, but some gaming, so we got the components that would work good for me. It's been one problem after another though. First the motherboard connections didn't line up with the back plate (fixed) then it wouldn't turn on (I didn't have the 12V connector in and I, uh, MAY, have blown the PSU before swapping it for a new one.) Finally I got it turned on, got so excited and hooked it up to my monitor (which I know works as it was being used yesterday on my old computer) just to find out that it had "no input signal." Here are my specs:

Intel core i5 3570K 3.2GHz (Ivy Bridge)
B75MA-E33 (motherboard)
Corsair 8GB (2x4GB) 1333 DDR3 RAM
Toshiba 1TB 7200RPM HDD
ThermalTake TR2 600W PSU
MSI S-6812 Case
Gearhead triple format 24X DVD drive
Integrated sound card with mobo
Graphics is integrated with CPU, Intel HD 4000

When I first installed everything I didn't know to use standoffs, but it never powered on until I put the mobo on the standoffs (although when I clicked the power button the fan moved a tiny bit) so I guess it could be shorted, I don't know how that works exactly though. I've heard no beeping even though all the wires are hooked up. I looked through the one list with about 99 suggestions and tried them to no avail.

Thanks for any help everyone, I really really qppreciate it. I'm getting desperate and about ready to say to heck with it and just buy a pre-built computer for $300 more.

EDIT:
Forgot to mention I tried another monitor to no avail
