I have read quite a few places where people with 1155 boards are having problems waking their pc's from sleep mode.
I am also having this problem.
I have not read of a solution, every one (who doesn't have an 1155) say that it is a windows 7 problem and to reinstall your os.
My conclusion is that it is a windows problem, but we will have to wait months for an update from microsoft to fix this problem.I have not yet updated all of the current updates, so perhaps the fix has already been released.

Perhaps your problem with the computer turning it's self on is related to your pc not waking from sleep mode, but what i would try is after your pc shuts down, remove the power switch wires from your mobo to see if the problem is in your case/switch or even possible static electricty. The wires are most often the blue/white wires.

Keep us updated of your progress.

Hi micro and thanx for your promt reply!

I tried disconnecting the PWR SW cable (orange/white) from the JFP1 slot at the motherboard.

As long as the PWR SW was disconnected the computer DIDN'T (!!) restart. I shut down the mainpower and reconnected the PWR SW once again and the comp instant rebooted after power on again.

So this semisolved the problem, now we know what the problem is. I wonder can i change the PWE SW to any other slot or is the ones at JFP1 dedicated for this. (Sorry for souch a dumb question, im realy not good at this).

If not, is there anything i can du besides buying a ner MoBo?

Regards
Thomas

The problem is the case, power switch or the cables are connected wrong, rather than the mobo having a problem.
Rather than getting a new case, you could try using the reset switch as your power switch. Just connect those cables to your mobo power on switch.This may or may not resolve the problem, then you can just use your rest switch for your power switch.

Also, recheck that your cables are connected to the mobo properly (look at writing on mobo as well as user manual) Some times the wires connect vertically and sometimes they connect horizontally to the mobo.

.
Based on what you've said, I agree it's most likely the power switch subassembly (switch-wire-connectors/wires/switch).

However, it could be improper connector usage but if it's intermittent then I doubt that is the situation.

I also agree with micro to look at the motherboard labeling of the connector. A motherboard might be revised and the manual remain unrevised. You should also check if there is a download for a later version manual at the manufacturer's website.

And in case you were thinking maybe you got the power switch wiring backwards...
The power switch is non-polarized. That means it doesn't really matter which wire connector from the switch goes on which of the two front panel power terminals on JFP1 terminal block, even if in the generic instance one wire is labeled for example P+ and the other is labeled P-. P- can plug into the JFP1/PWR+ terminal and P+ can plug into the JFP1/PWR- terminal (if that's how they are labeled). That is NOT necessarily how any other connections on the mobo work...this applies just too the power and reset buttons. (the "PWR+" and "PWR-" labels are an assumption on my part for the example on what the label for JFP1 terminal block on the mobo says. It could say something else, like simply P+ and P- or E1 and E2, etc.)

Similarly IF you have just a single 2-pin connector from the switch with 2 wires in it then it doesn't matter which way the connector is connected to the 2 pins on the terminal block (your use of a single "PWR SW" label suggests this may be your setup, but I didn't want to assume). Some cases use a single 2-pin connector, others use two 1-pin connectors on the switch wiring.


edit:
corrected 2 labels

Thanks for your answers guys!

I tried to reverse the + and - poles on the PWR SW/mobo but without success, after trying this i also tried the other way by taking away the PWR SW and and instead i used the restart "console" or cable or what you call it.

Now the computer seems to be fine!! I tried two shutdowns without any restart trouble!

I now use the restart button to as my power button.

A great thank you to both! It was quite easy to fix but I would never ever have done it this way without you. Probably id sit for a month longer with software's and then buying a new mobo :D


Just for funsies. Do you think there was a error in the cable/console since the slots work with the restart cable?

Thomas

It is a bad switch on your case.
