It's nice when it turns out to be something simple in the end

The button might have been stuck pressed in after moving around the case etc.
The button functions in the same way as the Clear CMOS jumper, if it is in a
shorted state the system will not power up.

Glad to see you are up and running again

Thank you for advice, upon removing MB from the case, i noticed a small button that sit underneath the DVI display port. A reset cmos botton , not a noticeable button from above as DVI port block it, but never the less and important button.

Seems like the process to clear cmos, not only includes battery removal and jumper position changes but as well as pressing this button. It is sad the manual does not include said task.

PC has booted up and i have access to the bios ]]> Fri, 26 Jun 2020 04:14:26 +0000 https://forum.asrock.com/forum_posts.asp?TID=14759&PID=76780&title=z97-not-booting-up#76780 https://forum.asrock.com/forum_posts.asp?TID=14759&PID=76761&title=z97-not-booting-up#76761 Author: Xaltar

Try the breadboard setup, that will rule out anything like shorting caused by
screws that may have fallen into the case or, stupid things like wasp nests etc.

Another option is to bridge the PSU power on pins (google how to turn on a
PSU without a board connected if you don't know how). Typically this is done
with the PSU disconnected from the motherboard but what you want to do is bridge
the pins from the back of the connector while it is connected to the board.

If that fails, there is the hail mary option. With the PSU plugged in to
power and turned on and the 24 pin power disconnected from your board, slowly
connect the 24 pin power at a slight angle so it only makes connection with
some of the pins. With any luck the PSU will come on then push it all the way
in.]]> Thu, 25 Jun 2020 13:30:11 +0000 https://forum.asrock.com/forum_posts.asp?TID=14759&PID=76761&title=z97-not-booting-up#76761 https://forum.asrock.com/forum_posts.asp?TID=14759&PID=76745&title=z97-not-booting-up#76745 Author: tequila1981

So i have removed the suspected psu (from PC1) and attached it to another PC(PC2), just connected the main power and 12V cable and PC2 booted, fans etc started to work. Took the PSU from PC2, which is working order and connected it to PC2's MB, just main power cable and 12V cable. No power.

Removed all additional fans, graphics card, hdd cables and 2 sticks of RAM (all 4 slots are filled) from PC1 MB, connected the removed PC1 PSU again MB, main power cable and 12V cable. No power. the only thing i had not done the remove the entire mb from the case just ran the breadboarding techinque, looks like mb is destroyed?

So pressing the power switch does nothing at all, no fans come on?

If that is the case, try a different PSU. I see you "tested" it but bare in mind
you can't just hook up a multi meter to a PSU and read voltages off. It will behave
differently under load. It could have a bad capacitor that works fine with no load
then chokes when load is applied for example. Then there are other factors like
current ripple, power protections etc.

If another PSU doesn't get the board to power on then pull the board out of your
case and connect it up to a PSU sitting flat on a non-conductive surface. This
is typically called breadboarding. You can find guides on how to do this by
searching google for "PC Breadboarding".

Good luck and get back to me if this doesn't work, there is one last thing I
can suggest but it is a bit of a Hail Mary.]]> Wed, 24 Jun 2020 13:08:20 +0000 https://forum.asrock.com/forum_posts.asp?TID=14759&PID=76727&title=z97-not-booting-up#76727 https://forum.asrock.com/forum_posts.asp?TID=14759&PID=76719&title=z97-not-booting-up#76719 Author: tequila1981

Make sure the CMOS jumper isn't still in the clear position, I have done this
myself once or twice and beat my head against the wall for hours trying to figure
out what was wrong

Failing that, power the system on and give it 5 mins, it may just need to
reinitialize after the full CMOS clear. You pulled the battery which clears all
settings including the Real Time Clock (RTC).]]> Tue, 23 Jun 2020 01:08:11 +0000 https://forum.asrock.com/forum_posts.asp?TID=14759&PID=76651&title=z97-not-booting-up#76651 https://forum.asrock.com/forum_posts.asp?TID=14759&PID=76648&title=z97-not-booting-up#76648 Author: tequila1981

Good day
I have a z97 extreme 6 MB. I attempted to set the admin password on the bios, system seemed to have accepted the password. On rebooting the system, the password was invalid, i assumed it was due to the specials characters i used in password. I read, in an online article by resetting the bios this can reset the password. Disconnected peripherals and psu, moved the cmos jumpers, pulled the battery out and left it to stand for 4 hours, naturally i was grounded. Everything was put back to together but the pc doesn't want to boot up. I have tested the PSU, it is providing power. I have tested cmos battery which is fine as well.

What else can i do to diagnose the issue?
