Problem with Aurora R4. Wont start boot at all.

Having a major problem with my desktop PC.   I press the power button and the fans start blowing, the vents cycle up and down, then immediately after the fan dies down to an idle level and nothing else happens.  screen remains black, no power to USB devices like keyboard or mouse.    Tried inserting windows cd but it appears that its not getting far enough into the boot procedure to attempt to load the OS from either the hard drive or the cd.   I was repeatedly trying to turn it on and off and actually one time it did boot, and I knew something was different because this time the colored case lights came on.   When the image finally came on the screen, it said previous attempts to overclock had failed and it was restoring a previous configuration.   I thought the computer just had a minor error so I used it, everything worked fine and after shut down again.    Now it wont turn on again no matter what I try.  I've followed all steps to troubleshoot, I've cleaned out all dust from the interior.   Not sure what I should try next.  Please help me out with this issue.  Never had any major problems with my pc before.    I have had an issue with the display not coming back when the computer goes into a sleep because of power saving issues, would also like to resolve that as well  since I am wondering if these issues are somehow related.
