Overclocking problem?

[Thelost1]

Within the last year I purchased a g30/ab. In the last few months every time I turned the computer on it took several attempts (2-10) It would come up with a message saying overclocking failed. I go into bios then exit and it would work. Today it took me roughly 300 attempts (3 and a half hours worth) to finally get the computer to a point where everything would turn on and I had the option to run bios. The computer and everything works fine but the screen mouse and keyboard wouldn't turn on . Is there anything I can do to fix this, preferably without me turning the computer off. Im scared if I turn it off again that it will never go.
specs are gtx 760 (192 bit) I7-4770k cpu @ 3.5ghz 16g ram

Well this has been a most helpful waste of time

Have you tried the basics?

• ensure the main battery actually holds charge, or keep it plugged into an AC power source
  
• clean/blowout any dust which may have accumulated, especially around keyboard and exhaust ports
  
• reseat all the DIMMs, drives, and other user-accessible cables/connectors which might be loose and wiggly
  
• update your BIOS
  
• replace the motherboard CR2032 battery
  
• if system is stable enough - run diagnostic software/tests, to identify if some critical component is failing
  

Any chance the unit suffered a drop, crush, or spill?
