PC hit with successive power surges among other problems. Please help.?

I have a custom a1750y Series HP desktop pc 3 gig. It was hit with successive power surges Saturday.

I had already copied my files as I was preparing to reinstall the master disc because of it's odd behavoir. After the initial surges were over, I didn't see anything wrong witth pc. So Sunday I got up and performed the master disc installation as I had before. Knowing the process would take about 2 hours, I went to sleep. When I woke, the screen was black and the pc in hibernation. I thought it was ready. But unfortunately I was wrong.. It was stuck in it's reboot system and idiot me turned it off. It is still stuck in reboot, has been since then, ever since 2 p.m. yesterday. The message I have on my screen is :DO NOT turn off your PC during this one-time setup process. Your PC restarts several times during this setup process. Messages may pop up onto your screen. Ignore these messages until you are prompted to Restart or Shutdown your PC. Please wait. I've tried getting it into safe mode thinking it would just stop. Nope. I've even reinstalled the disc(s) thinking a second reinstall would clear up the problem. Nope. Does anyone have a solution? Honestly, I think the system got fried. But who knows. Thank you all in advance. .
