My PC won't POST - please help

[InCogneato]

It all started when I changed the memory's reference frequency (FSB / memory ratio) to the lowest so as to make my memory faster. After I did this the computer just wouldn't POST at all. I've done tons of other changes to my BIOS, and memory changes sometimes caused it to not POST either. But usually I'd just take out the sticks and put 'em back in and it would POST (BIOS would have default settings applied I guess). But that isn't working. Neither does another set of memory I have here. Neither did taking out the CMOS battery for 30 minutes to try and reset the BIOS. I don't think there's any error messages or beeps. The fans and little lights on the inside of the case turn on. My MoBo is an Intel D975XBX2. Everything has been working fine for over a year now.

Any tips, ideas, or suggestions would be appreciated. Thanks.

nvm figured it out. i started messing with the jumper settings and while the recovery mode yielded nothing, the advanced config mode got me into the BIOS. i was able to change the problematic settings and am now in windows.
