New CPU not working PLEASE HELP

Hello, I decided to upgrade from dual core to quad core and unfortunately I only have a LGA775. I didn't want to spend too much money on a new motherboard and processor so I got a Core 2 Quad Q9450 2nd hand. When I put it in (and I did put it in correctly) and started up I got no signal on my monitor and no beeps or anything, fans and everything was running fine, CPU was warm when I took it out. PSU is fine and brand new, and the processor still worked in another computer.


Motherboard: ECS G41t M13 LGA775
PSU: Thermaltake Litepower 650 watt
Current CPU: Pentium 4 dual core 3ghz
GPU: GT430

BIOS version: 04/10/2012 latest for my board

Old CPU works fine in my PC so there cant be anything wrong with other hardware. Not a BIOS issue because I have the latest version. I thought about resetting the CMOS but if I want to do it have to drive out to the guy who is selling the CPU to test it and he lives far away from me. So my question is: If I reset the CMOS one of the 3 different ways will it definitely work?

  1. Should run.

    All I can think is if you have really slow memory in your system it may not work to well with the new CPU due to the higher speed the memory will have to work due to the higher fsb of the new chip.

    Old chip fsb is 200mhz, new chip fsb is 333mhz.

    What speed is the existing memory?
  2. 1333mhz ddr3
  3. Ah didn't see it was a ddr3 board.

    Download the manual and clear the cmos yourself, should just be shorting two pins.
  4. So you reckon cmos should do the trick?
  5. Best answer
    Theoretically the board should do it itself when a new cpu is installed but then again its a ECS so it might need prompting!

    Nothing to lose as you know the cpu works.
  6. OK thanks very much
