New CPU, no boot

I upgraded froma 2.6C to a 3.2E processor. when I go to start the computer the lights flash and the fans spin real quick but the computer powers off.

I have a 380watt Antec power supply and a Intel D875PBZ motherboard. I disconneted a hard drive and CD-Rom to see if that would help. If it was a power issue. Could this still be a power issue or could it be a bad processor.

I replaced the old processor and it boots fine. Any suggestions??

  1. You may need to upgrade the BIOS by flashing it. Try defaulting it first. Hopefully, you made your self a BIOS Rescue disk before you started this.

  2. Thanks. I checked the BIOS and its on the latest version and there is no way to load the defaults. I can load optimal and custom. They have the CPU setting loced down.
  3. When you update the BIOS you need to default to make it the default BIOS. Short the pins on the jumper next to the CMOS battery and try again.

    That's right, not all versions supported Prescott CPUs.

  5. Sounds like a great reason to get rid of the heater, and get the P4c 3.2.
  6. Thanks for the help. Im not sure why the motherboard want working because as for the BIOS and Revision number it should have.

    I went out and got a new motherboard and the new cpu is booting fine. I just now have to reinstall everything.
