PC Won't Wake up from Sleep Mode

I have an HP Pavilion p7-1154

I literally did a complete reformat yesterday, and did not have this problem prior to reformatting.

Since then, every time my computer goes to sleep, I cannot wake it up.

Moving the mouse, pressing a key, or even a short press on the power button. I have to manually power it down, unplug it, let the reserve light drain, and then turn it back on.

I tried to Google, but I can't find anything that isn't a bunch of blind leading the blind. I am fairly proficient with computers.
