Hi,

I format my PC (Celeron 446) and change BIOS setting to default. Now When I boot my system, a message appear in red colour " System Hardware Abnormal" and system does not boot up.

Does anyone know whats the problem and how can I solve it.

What reason did you change the BIOS for?

Have you been back into the BIOS to check that it's settings are correct for your hardware?

Turn off the computer, remove its cover, restart it, and make sure the CPU's fan is running. If it's not, then replace it.

If the fan is running, then go into BIOS, and disable an item called 'CPU Fan Detect'(or similar).

If you cannot get into BIOS, then reset CMOS either with a MB jumper(see MB's instructions), or by removing the CMOS battery for at least an hour.

If that does not work and the CPU's fan has a 2-pin connector which is connected to a 3-pin fan terminal on the MB, then get a CPU fan with a 3-pin connector.

Hi

I replace the CPU fan and it works. Thanks a lot Ski.

You're welcome.
Glad to hear that you fixed things, and thanks for posting back with the solution.
