Question PC wont boot after turning XMP on

[denysk]

I just installed new 3200 ram into my motherboard. i cleared the cmos and pc booted into windows just fine the first couple times. I tried running the ram at 3200 at 1.35 which is what it's supposed to run, then the PC wouldn't boot because of system instability. I didnt know my motherboard only went up to 2666. I tried turning XMP on and when I tried booting the pc, my screen just kept saying "no signal, check your input!" then "no signal, check your input! entering to power saving mode..." an led on my motherboard is lit up saying power and boot. I cleared my cmos several times after this with the same results. I also tried my old ram which takes up all the slots (the new ram only takes 2) with the same results. I also tried no ram at all and my motherboard says power and dram, my screen is also just completely black.

Was your PC unplugged when you cleared the CMOS?
What is the name of your motherboard?
