Why did you replace the PSU in the first place? What were the symptoms before? Obviously, you need to double check to ensure all the necessary cables are properly and securely fastened.

The system was not plugged in for about 3 months. Any chance that I need to replace the battery that looks like a watch battery?

Well, that was certainly my first thought. And sadly, that "something" would likely be the regulator circuits on the motherboard, and if really unlucky, everything plugged into that.
I'm hoping that it is a simple fix and not that something downstream of the PSU blew.
If you are certain this new PSU is good, and all power cables to the motherboard (there are typically 2, sometimes 3) are fastened, then about all you can hope for is a cable was knocked loose during shipping, or while replacing the PSU. Or perhaps the CPU HSF assembly came loose during shipping.
Unplugging from the wall, touching bare metal of the case interior to discharge static in your body, then moving the CMOS reset jumper for a few seconds will reset the BIOS. Replacing the CMOS battery will also reset the BIOS (again, with system unplugged). The battery should not be bad due to 3 months of no use. But they are cheap so you are out little for trying.
I saw another post for a different type of computer that suggested pulling all power from the system, removing PCI cards and then changing a jumper temporarily and then returning everything back to the way it was.
Without a spare CPU to try (and perhaps sacrifice), I am afraid there is little hope of troubleshooting this on your own. About the only thing else to try is one stick of RAM at a time.

Anyone who says they haven't been there are probably lying to you!
What a doofus I am. I missed one small cable that needed to be plugged in. Thanks for making me take a closer look at it again!
Glad you got it sorted out and thanks for the followup.
