I do have one problem I purchased a used intel D925xecv2 mobo I think I fried it 
it will not boot I tested the Processor and the memory in another unit these are working fine I switched out the Video card and it still kept giving me just a black screen what happened was I had it up and running and I disabled the intel speedstep option to get the frequency to stable out because it kept on jumping between 3.4ghz and 2.8ghz well even after I disabled it it still kept jumping up and down so what did I do I decided the play with the memory timings I set it to aggressive and thats all she wrote 
well if anyone can help me get this board up and running again I would appreciate I tried doing a BIOS recovery but to no avail thanks for hearing me out hope to hear from anyone soon the specs on the unit I burnt out are as follows: CPU: intel 775 650
Memory: Corsair value DDR2 533 PC4200 2x1gb
