Computer Won't Boot After Uninstalling HDD

Recently upgraded to new Cpu(LGA155 to 1150),MoBo, and PSU. I got it to post and it went into some HP data recovery. The recovery was not really working so I thought I could bypass it by uninstalling one of the hard drives that I happened to salvage from an old HP computer. I press the power button with the one drive installed and it turns on (Fans spin up and LEDs lightnup) for maybe half a second and shuts back off. Ive tried the other hard drive, both of them, and none of them but it keeps shutting off. Both have windows installed. CMOS ressetting did nothing and I just need to get it back to where I had it. The graphics card, RAM, disk drive, and both hard drives come from a previous working build. I had it all working before I messed with the hard drives.

SPECS:
MSI Z87-G45 Gaming Motherboard
Intel Haswell I5-4670k
MSI R7770 GFX
Corsair RM750 PSU
Corsair XMS3 DDR3 4GB RAM
Seagate Barricuda 1TB 7200RPM-
Windows 7 32-bit (from the HP)
Seagate Barricuda 500GB 7200RPM-
Windows 7 64-bit

You can't use your existing Windows install to boot from.

You will need to reinstall Windows.

Try booting from a CD and see if that makes a difference.

If not, there's something wrong with the hardware. Might be power related if it's shutting off and the motherboard isn't booting.

Also make sure your videocard is plugged into the PCIe power plug if it's required.

New CPU and motherboard almost always requires a clean install of the OS.

Remove all HDD's but the desired target drive, and install fresh.
Assuming these aren't OEM installs from HP. In which case they are licensed to the original motherboard.

Do you have the license key(s)?

Check and make sure everything is pulled in firmly. Sounds like you may have shorted your power supply if that didn't work. I would try another power supply.

Just got the computer to start up, I basically unplugged everything and plugged it back in. Not sure what was wrong with it. Also it loaded up both HDDs and Windows is working fine without having to unlock it or anything. I will report back if I get the issue again. Thanks anyways!

Copy your files from one HD to the other and format it. You'll get blue screens soon enough
