Computer won’t power on after BIOS flash
Lockedby carol · about 24 years, 7 months ago
I have an ASUS P2B-F mainboard. I am running Win2000 Prof. OS said that COM ports weren’t functioning properly so I flashed the Award BIOS to rev 113a. It loaded successfully. I rebooted, went into the BIOS and clicked on “Load BIOS Defaults” instead of “Load Setup Defaults”. I saved it and went into Windows with no problem. I shut down Windows about 2 hours later and turned the computer off. Later when I tried to start the computer I get a blip of power and the fan doesn’t come on. What can I do?

Try the following steps:-
1. disconnect the power cable from atx cabinet.
2. open the cabinet.
3. see from the manual of motherboard where is the cmos enable/disable jumper.
4. do as intsructed in the manual to clear cmos.
5. disconnect HDD from main board.
6. power on the system to see if it boots up (correct the jumpers to the previous state).
7. if the system boots then shut down.
8. disconnect the power cable.
9. connect the HDD to motherboard.
10. power on the system after correctly setting the bios.
11. in case your system doesnot powerup then there is some other problem.

The manual didn’t seem to have any way to clear the CMOS on the board. I took out the battery for a while but it still didn’t power up. I have since installed another BX440 Gigabyte mainboard and the system booted up fine so it definitely wasn’t the power supply. I still want to get this board up and running and learn from this experience so if you have any other suggestions I’m ready to try them.

alternatively if you have a friend that can programme eproms you can remome the eprom and give him the saved original bios program.

Sorry about the partial answer but my modem droped out only sending part of reply. So here goes again. some main brds allow a return to fail safe bios settings while holding down a key during total pwr up ie from mains skt or rear switch not the front panel switch, some ABIT brds use the insert key. If this does not help then if you have access to an eprom programmer then you can program the bios eprom with the save bios binary file you saved during the update that I hope you did.

After the flash I went into the BIOS and clicked on Load BIOS Defaults which was suppose to be the fail safe BIOS settings and when I saved & exited the screen said that the new revision was loaded. It was only after a cold reboot that I coudn’t get any power. Holding a key wouldn’t work since no power is even getting to the board.

Disconnect power, open case, remove cmos battery for about 1 hour.
Replace battery and seen if system will reboot to previous conditions.-

Thanks! Taking out the battery for a longer amount of time was the trick.

Hi Carol If as you say there is no power to the board, then it is one of 2 things all atx power supplies have 2 power supplies inside the psu box, the 1st is a standby supply which provides 5V only at upto 700mA which runs all the time power is applied and the rear switch if your case has one is ON, the 2nd is the main power supply which is started by the front panel switch from power supplied by the 1st power supply, to check which psu is at fault you either need a volt meter or if you are lucky some mother boards have a standby psu indication lamp (led) to show that the standby power supply is working, if this is the case then either the front panel switch has failed or the 2nd power supply is faulty. I hope this is a bit more helpful than the last posting.
Best Regards

Thanks for the help but there wasn’t a switch on the back of the power supply.
