PC won't boot after overclock attempt

[WizardsAreNeverLate]

Hi all, hoping I can get some help with a new PC build and my first attempt at overclocking. The components are as follows:

Mobo:
ASRock A75M FM1 AMD A75

CPU:
AMD A6-3650, 2.6Ghz

RAM:
G.SKILL Ripjaws X Series 8GB (2 x 4GB) SDRAM DDR3 1600

PSU:
Antec NEO ECO 400C 400W

SSD:
Crucial M4 64GB


I assembled the system last week with Windows 7 and it was running without a hitch. Having read about how this processor overclocks well, I increased clock speed through the BIOS overclock feature from 100 Mhz to 105. Went to reboot and now the motherboard won't post. The system turns on, fans are spinning, but no video output, no system beeps, nothing.

I tried to reset CMOS via the jumper, and removed the battery for 12 hours as I was hoping a reset of the BIOS would help, but that didn't do anything. Not sure what the problem could be so any input is greatly appreciated.

Can you remember how many volts you put through the CPU

I didn't modify the voltage, it was running at the default 1.4V
