680i lt Help Please!

[darkpark1]

i have a xfx 680i lt mb,intel q6600, ocz sli ddr2 800mhz 2gigs ram, xfx 8600 gt xxx edition, and an ultra x2 750 watt psu. I have vista 64x and have had my system up and running for about 2 weeks. Today i tried to up my timing on my memory. I went into bios and enabled SLI memory and set the settings to optimal timings. I saved it and restarted...... then nothing... no video... no bios... nothing. The fans lights everything spin up but no video.. DID I FRY SOMETHING??? Is it just the memory settings in the bios thats messed up??? I dont know what to rma first. The motherboard, cpu, videocard, Ram, psu or what... any help would be greatly appreciated.. thanx

Odds are the system is just locking up... clear the CMOS. Pop the small battery out of your motherboard wait a few minutes, put it back in and try booting again. This will set your BIOS to the factory default settings.

*Edit*

Oh, and if you did fry something due to overclocking, good luck getting an RMA...
