PC doesnt boot anymore

[DuPaCa]

Everything was going alright on my OC'ed system (4.2 gHz). I noticed i could still OC my system more so I went tot my BIOS to OC it to 4.4 GHz. I also powered my fans a bit down.
Now suddenly my PC doesnt even boot anymore. I cant get to my BIOS anymore because my keyboard doesnt even power on. My screen also detects nothing.
What should i do now??

PC specs: AMD FX-8320

Unplug the power and on the motherboard there will be a "jumper" to cross to reset the bios to factory specs. Connect the power and try too boot the system if still dead you cooked the CPU or motherboard or both !

OC failed, so clear CMOS to return BIOS to default settings. See downloadable manual for location of CMOS jumper.

JBAT1 : Clear CMOS Jumper
There is CMOS RAM onboard that is external powered from a battery located on the mainboard to save system configuration data. With the CMOS RAM, the system can automatically boot into the operating system (OS) every time it is turned on. If you want to clear the system configuration, set the jumper to clear the CMOS RAM.

Important
You can clear the CMOS RAM by shorting this jumper while the system is off. Afterwards, open the jumper. Do not clear the CMOS RAM while the system is on because it will damage the mainboard.
