I have a 5 year old PC.. about 2 mouths ago I put in windows 7 everything was working fine until this morning..

this morning I turned on the PC.. and it shut off right away.. I took the side cover off and a 9.F. code on my Abit mother board..

9.F. == µGuru force shutdown
meaning it will turn on, for about 4 secconds then it will shut its self back off and display an error code of 9f

I Replace the 400w power supply with a 550w power supply

But I can not get the PC to even give a bios..

this is from Abit them self..
9.F. µGuru force shutdown 1. Power on -> Stop at 9.F.2. 0.0.->8.3.->9.F. repeat 1.Restore default setting for BIOS2. Replace with other power supply
µGuru load default Settings

Turn ON your PC with our µGuru™ motherboard and then turn OFF right away as one single action; repeat this action continuously for 3 times.

dose not work for me.. did both the power button and the power supply switch..

any help would be useful..
thank you

Try resetting your BIOS defaults, as stated.

How to do CCMOS Action

Step 1:
Turn off AC power, move CMOS jumper from 1-2 pin to 2-3 pin for 5 seconds.

Step 2:
Turn off AC power, move battery (3.0 volt CR2032) on the motherboard for 5 minutes and put it back.

still nothing.. it is weird that nothing was wrong yesterday.. I did no updates.. There were No beeps at any startup..


could my motherboard be dieing????

After replacing the PSU, next assumption is probably a failing board.
