Satwik Mahapatra · Apr 22, 2015

Hi I am using windows 7 ,my mobo is asus p8z68-m pro .
my computer keeps restarting after shut-down ,but after i reset the bios the pc shuts down properly for 2-3 times but again it keeps restarting.please help.

What is your BIOS version? If it's older than version 4003 I'd suggest you install the latest version which can be downloaded at the following link. Restart issues are not uncommon with buggy BIOS versions and that motherboard has had a pretty fair number of system stability BIOS updates so it's highly likely updating to a newer version will end your troubles. If you already have version 4003 I'd suggest unplugging the power supply from the wall, removing the CMOS battery and pressing the power button for 30 seconds then reinstall the CMOS battery, plug the unit back in and restart the system to test it out. You may need to reset your BIOS settings if you've changed any from the default values previously.

I updated my bios version to 4003 the problem is still there.I removed the battery and cleaned the bios now there is a red light in my motherboard which is on and no display is coming out .

Darkbreeze · Apr 23, 2015

I'm not sure what you mean by removed the battery and "cleaned" the bios.

So you updated to the newest BIOS version, restarted after updating, and the problem was still happening?

So then you unplugged the unit from power, removed the cmos battery, pressed the power button for 30 seconds, reinstalled the cmos battery, plugged the unit back into the wall and the computer won't power on now?

Did you mean "cleared" the bios?

Where on the motherboard is the red light and is it flashing or solid?

sorry for my earlier post the pc was not starting up because the rams are not set properly,now its ok pc is starting up properly but still when i try to shut-down it restarts after 3/4 second.

I already updated the bios .
reset the bios
reinstalled the OS.
unchecked wake up on lan or any usb device
nothing worked.
now whenever I have to shut-down the pc I have to switch off the power supply from the back .
When ever I switch on the back psu switch ite pc starts I dont have to press the power button.

What is the model number and brand of your power supply? This is probably either a faulty or cheap PSU issue or a problem with the motherboard.

Satwik Mahapatra · Apr 23, 2015

My power supply is seasonic 620 watt, how to know which one is not working?I dont have a spare psu to check is there any other way to sort it out?

Darkbreeze · Apr 23, 2015

Well, that's a pretty darn good PSU so it's possible it's the PSU, but it's a lot less likely than if you had a cheapo model.

Try booting into Safe mode and see if it will shut down normally from safe mode. To access safe mode power on the computer and press F8 until the advanced boot menu appears and choose safe mode. Once in safe mode, allow the desktop to fully load and then choose shut down. If it shuts down normally five or six times like this then we know it's a software issue and not hardware.

Satwik Mahapatra · Apr 23, 2015

already tried the safe mode,even in safe mode this thing happens every time ,if i reset the bios from the switch in MB only for the first 2/3 times the pc shutsdown properly then again it keeps restarting.

Try disconnecting the two wires coming from the front power button of the case to the motherboard then briefly touching those two pin together (Not the wires, the pins the wires were on) on the motherboard to start the unit up and then try to shut down once you're fully in windows to see if perhaps there is a problem with the front power switch that's causing the issue.

Satwik Mahapatra · Apr 23, 2015

ok I tried ,I removed the power and the reset button and shutdown the pc by shorting the two pins now it takes longer time to restart after shutdown,if it was restarting after 4/5 second after shutdown now its 15/20 second.

Darkbreeze · Apr 23, 2015

No, I didn't want you to shut it down that way, just start it that way. Shut down normally from windows.

You know, just for giggles, go into Control panel power options, on the left side click on "choose what the power buttons do" and make sure that it's set to "when I press the power button"="shut down" and "when I press the sleep button=sleep. I don't think it's related but just make sure.

Before I reinstalled my os I was playing far cry 4,the pc was working fine only the restart problem was there.even now everything is working properly only this problem.

Darkbreeze · Apr 23, 2015

If you shut down from the windows start menu button as you normally would, with those wires disconnected, what does it do?

Darkbreeze · Apr 23, 2015

If none of that works, reconnect the wires from the front panel and try this:

This could be down to the AutoReboot setting kicking in.

1. Click Start > Run and type REGEDIT

2. Click the plus sign next to HKEY_LOCAL_MACHINE
then System
then CurrenControlSet
then Control
then CrashControl

3. Double-click on AutoReboot on the right side panel and change the value from 1 to 0.

Close regedit and restart the computer. Now the computer should shut down normally instead of restarting.

same result with windows start menu button keeps restarting

Satwik Mahapatra · Apr 23, 2015

Auto reboot value is 0 I changed it to 1 nothing happened.

Satwik Mahapatra · Apr 23, 2015

I even removed the hard disk and its still restarting.help me guys.

Darkbreeze · Apr 23, 2015

Satwik Mahapatra :

No, you want it to be 0. If it was already 0 then that wasn't the problem. I'd change it back to 0 or we'll never figure it out. I've got to go take care of some service calls but I'll try to help figure this out some more when I get back later.

Darkbreeze · Apr 23, 2015

Are you shutting down by clicking shut down on the start menu or are you using the power button to shut down? Try pressing the power button until the unit shuts down and see if it still restarts. After you reset that value to 0 of course.

Satwik Mahapatra · Apr 23, 2015

Sorry for my let reply darkbreeze,I think I found the problem when uninstall the network adapter it stopped restarting.Now what should I do?

Darkbreeze · Apr 23, 2015

Try reinstalling the network adapter and then going into it's device manager properties and disabling it's "wake on lan" and also it's "allow the computer to turn this device off" features.

I'd also see if there is a newer device driver available for it on the motherboard product page.

Satwik Mahapatra · Apr 24, 2015

Thanks darkbreeze its working,installed the latest drivers unchecked wake on LAN and its working for now,man you are a genius .thank you.

Darkbreeze · Apr 24, 2015

Not a genius, I just don't give up easily. If I was a genius I might have thought of that in the first place. Glad it worked Satwik, good luck to you.

Satwik Mahapatra · Apr 25, 2015

Well said,thanks man.Will let you know if this problem comes up again.
