ASROCK Z68 Extreme4 boot loop problem, will not shutdown!

post #1 of 15
Thread Starter 
Hey I got this board off a member on the forum yesterday and since putting it together the first time I put the power cord into the PSU the thing starts by itself and every time I try to shutdown, it turns off then powers back on by itself a few seconds later so I have to turn it off at the PSU switch

Is this a common problem with these boards and does anyone know what might be causing it? Any help would be great Im about to go nuts trying to solve it.

All settings are at stock, ram settings are configured manually. These are the things I have already tried:

1] Changed the ram for a different set
2] Took board out and tried running on a box to eliminate shorts.
3] Tried a different old CoolIT 480watt PSU I have, same problem.
4] Removing all devices except the ps2 keyboard and dvi cable.
5] Tried with onboard graphics and 6950 same problem with both, no difference.
6] Took off my A70 and install stock heatsink.
7] Reset cmos/ changed cmos battery.
8] Tried running with one stick.
9] Unticked every device in device manager that could wake the computer.
10] Changed every power saving, boot from keyboard, all features I could think off in Bios.
11] Changed the power cord.
12] Tried booting from linux live cd and shutting down but still boots up.
13] Tried different bios.



Im baffled. frown.gif Would like to get this sorted as I do love the board.

Have you tried running it with 1 stick of ram? something seems to be off redface.gif
I ran it again before sending it and it was all fine, no power loops or anything.

When you start the power (from PSU/mains) does it start itself (the motherboard) or do you have to push the power button? Or does it not shut down?

I've only ever had these loop problems with a few boards long ago (LGA775).
Have you tried clearing CMOS?

I keep misreading. :/

Have to push the button, I tried it without using any front panel connectors and just using the button on the board and get the same result. Yup cleared cmos and replaced with new battery.

After running memtest on 70% of my ram for 30% of the cycle I have had 4 clean shutdowns in a row so hopefully something has been fixed. I don't know how but I will not complain.

Edit:

I have now had 8 successful shutdowns, really do not know how running memtest could have solved this. I will bump the thread if the issue reappears!

Bump! Problem has returned out of the blue. Anyone any extra ideas or might have experienced something similar please share! Cheers

Sounds like you already checked this but I had the same problem until I checked: Device Manager->network adapter->power management->allow only magic packet to wake computer.

Before that it would wake almost immediately as soon as any packet reached the NIC.

Just tried that there now fxer, cheers but did not seem to help. I just find it weird that it disappeared for a day or two then comes back.

I actually had this briefly with my brand-new Asrock Z68 Extreme 4 Gen3 board last week.

It has gone away now, so I cannot identify my issue either.
