Red CPU Led On- Computer Wont Start

I used to have a pc with a phenom II X6 and since i felt that i rather get a sandy bridge rig, i bought an i5 2500K and ASUS Sabertooth P67, well after assembling the computer i attempted to turn on the pc and the bios came up but it made something like a buzzing noise and cpu + memory leds lit up also there was a message at post - i am not exactly sure but i think i saw it said short, after that all the pc would do is attempt to start but red cpu led comes up and computer dies

Core i5 2500K
CM Hyper 212+
ASUS P67 Sabertooth
ocz vertex 2 60gb ssd
seagate barracuda 500gb hard drive

3. New Motherboard (Asus P8P67 Pro)

  1. How long did you remove the CMOS battery for? Do you have a case speaker?
  2. i removed the cmos battery for about a minute, i was on the phone with an Asus rep and he told me to remove the battery for a bout a minute, yes i have a speaker i just didnt hear anything
  3. Wait at least five minutes.
  4. are you sure that will fix it, I don't have the p67 sabertooth anymore but the p8p67 pro, also Ian not sure if it's a short or not and if my hand brushed slightly the socket
  5. If the battery doesn't work, it may be your processor or motherboard. Were you wearing an anti-static bracelet?
  6. no I was not but now when I attempt to reassemble I will
  7. well i fixed the problem, it turns out that i pushed a molex plug too hard and one of the pins came loose and was shorting the motherboard
  8. I had a problem with red CPU light. No start beep. No loading of Bios. My problem was that i missed a 4 pin ATX 12V cable. First i only had the big ATX 12 V cable.

    Asus P8P67
