Default HTC Evo 4G Always Asks to Power Down or Restart

I have search the world over but I think this problem is unique and now I need some help.
HTC Evo 4G rooted with unrevoked-forever
I lost the use of my power button last month and searched that problem to find the solution is the Nolock app. Iím now using my volume buttons to wake up my phone. 3 days ago I noticed my power menu was on the screen asking me to either shut down, airplane mode, or restart. I touched the back arrow and thought nothing of it. Now itís coming up very often and if not attended to runs out the battery. In fact, the whole operating system is acting slightly goofy.
My thoughts were to go through the ROM redo which would take me an hour or more to relearn the process so I donít lock up my phone. Then I realized I donít have the power button the select menus in the flash process.
Am I at the end of my beloved 4Gís life? Any help with be greatly appreciated.
