Overcloking gone bad

[lfgd1978]

Hello world! this is my first post and English is not my first language so please keep that in mind when answering my question. If you have nothing useful to say please move on, nothing to see here.

First I'm not a n00b at building computers but I am a n00b at overcloking and sadly I made the mistake of overcloking my build too far (I when to 3.5Ghz from 3.3Ghz by moving the multiplier). I have tested every component individually on a different system and all but the motherboard seem to be working fine.

I have flash the BIOS, use the jumper to reset to default, leave the MB unplugged for a week, and nothing works. The computer just seem to reboot continuously and I get no video signal (I tested without the graphics card to the same result) I imagine that the motherboard is busted but I have found some people that claim to fix motherboards. My question is: Is it possible to fix this kind of damage? I'm I missing some miraculous fix? should I just cut my losses and forget about it?

This is my complete build:
Intel Core i3 Processor i3-540 3.06GHz 4MB LGA1156
Intel Socket 1156/Intel H55/MATX Motherboard
Corsair XMS3 8GB DDR3 1600 MHz
EVGA GTX 550 Ti 1Gb
Corsair CMPSU-430CX 430-watt Power Supply
Western Digital 1 TB Caviar Blue

How long did you leave the computer on during the time you OC'ed it?
Do you have the Stock or Aftermarket cooler?

When I reboot the system after modifying the clock, the PC lost video signal and I was not able to get into the BIOS, trying the jumper and the BIOS flashing to reset and restore the BIOS I have turn on the PC for a while quite a few times to no good result. I had the Evo 212 plus installed and the processor works fine.

Corsair CMPSU-430CX 430-watt Power Supply < Overclocking with a poor PSU is never a good idea.

The CX Series is for budget builds and not meant for overclocking.

Sure, but "in theory" I had power to spare since my power consumption (at peak) was around 283 watts. Besides, the PSU suffer no damage.

I think that my Intel H55 motherboard was the weak link in the equation, that and my trigger happy finger with the multiplier.
