After reset CMOS battery PC wont start

Did you unplug the power cable? Also, did you reset the jumper pin to clear the CMOS? After that, you should get a prompt at reboot to reset your BIOS configuration (usually press delete) and reset the BIOS to your hardware specs.

If you get none of this maybe you should try another CMOS battery...

Remove the battery and wait for 5 minutes to make sure its reset. It takes a little while for all the power draw to leave the motherboard from the battery. There probably is a CMOS jumper pin on your motherboard that you can also move, it should look like this:

Default - [o o] o

Reset - o [o o]

Wait for 5 minutes or so and move back to default and all of your BIOS settings should be reverted back to factory settings so you will have to go back and reconfigure your BIOS settings to your current hardware. If you aren't sure what the correct BIOS settings are to set them back to then try to go into the BIOS before you reset it if possible.

You didn't give enough time for the motherboard to lose the power draw from the battery so wait at least 5 minutes, it doesn't normally take that long but will do the trick...

Thanks for reply,

But the problem still persist, i removed battery for 5 mins and jumper reset for same time, means i remeved battery and kept jumper for reset at same time but problem still persist. Only keyboard blink just once and no fan movement including SMPS and processor and nothing on monitor(blank with power light blink) Main problem is no fan movement...

please reply me waiting for reply and thanks everyone again

Beleive it or not I have a similar problem on my Mobo, its an ABIT IN9 32-MAX WIFI. It just froze once and couldn't hold the power button to switch it off. I had to switch off the supply from the back. Once I turned it on again, the LED's in the mobo to light up but pressing the power button won't switch on the motherboard. all fans remain still. Resetting the bios, removing the battery never helped. Only once with the psu switched on, the fans started working but again I had to switch off from the back of the PSU. I don't know what the problem is. Tried changing the PSU and also tried my CPU on another pc and worked fine. There must be something wrong with the mobo. Any ideas?

Can this be a problem with the bios chip? Can we just replace the bios chip with one compatible with our mainboards and work? Remember I have similar problem, mobo won't start at all.

Obviously as I stated in that same statement you quoted me on. I have had instances where 10-15 seconds didn't work so it doesn't hurt to overshoot on the time it takes to be sure plenty of time has been taken.

Are you sure your power supply is ok? If you are certain it is then maybe you can check and see if there are any new BIOS revisions available and try and flash your BIOS to the latest version. Did you install new hardware/software recently that could be causing the freeze up? I'm afraid to say that ABIT's quality fell to the waste side and its likely to be a known issue with that board. Google your motherboard model and see if there are any other postings with the same issue.

I'm thinking power supply at this point. As old as your system is you have gotten way past the life expectancy of any power supply used in those systems back then. If you can get a power supply tester or just buy a new psu and take it back if it doesn't fix your issue. I just hope it didn't damage your motherboard on its way out.

You need to test or replace your power supply 1st. Check all of your connections to make sure nothing has been disconnected...

Sounds like you covered your basis and just need to work on the RMA.

To the OP, I would recommend the same thing, test or replace your psu. If that doesn't work then the motherboard could be bad too. It would be time to consider a new build or prebuild system. I prefer the new build, it's easy to do...
