I recently tried overclocking my Intel Core 2 Quad q6600 from the stock 2.4GHZ to try and make it 3.0GHZusing the bios on my mobo. I read that people safely did this at 3.2GHZ with a stock cooler so I just decided to go with 2.7GHZ. I used CPU-Z to figure out my core multiplier and it said it was 6. I changed my fsb to 450 which would be 2.7. After I saved the setting my desktop will not power on now. I tried resetting the cmos (left it out for 30 minutes) and pulling out each piece of hardware and testing it individually. All hardware works and the motherboard light comes on as green (not sure if that helps any). I have no clue what else to due. Please help! By the way my motherboard is an Intel DG43RK using Kingston 2x4GB DDRE 1333 memory.
