Hi,
I thought i might give it a shot and try to ask for help here.
My Computer recently starts itself (about 1 hour after i shut it down), shuts down immediately(no fans running) and then starts requiring me to recover my bios settings.
After that is done the Computer works just fine.
I've tried several things already like: unplugging USB Devices, unplugging my LAN-cable, turned all different kinds of "Wake on..." off.
I have also unplugged the power cable(for 5 hours or longer) and after i have put it in again to start the computer the exact same thing happens when it starts itself.
Maybe you guys have got a solution for me.

Replace the CMOS battery on the motherboard.

I would immediately contact a priest to come perform an exorcist of your home. You can never be too sure.

This happens only ones every time?

With the crucial m4 ssd there was a bug that after a certain period of usage it would give problems like these which could be resolved by updating the firmware.I think in this case would it happen over and over though.

Maybe just update the bios? Do you have the latest version?

Yes it happens only once every time and yes I have already updated the Bios.
What I have also figured is, that it only happens after I've used the Computer for over 2 hours

What hardware are you using if i may ask? Also include the psu.
For the pc's hardware (except the psu) could you use the following,

Download hwinfo32,
http://www.hwinfo.com/download32.html
when opened click run,after that close the "system summary" which is the top window,after that click "save report" on the left hand side top,after that check=dot "short text report" click next,in the next window you'll find your hardware,copy this here.For that could you use the "copy to clipboard" button in the window and right click paste in your next post.

Have you checked energy settings? In the bios (if there are any) or windows.

The problem with the energy settings is that everytime my PC starts itself all my Bios settings get reset as far as I'm concerned.
As i mentioned before i always get to the "Bios Recovery".

Did you replaced the motherboard battery?
Also save the optimal default settings after that.Take a look at the time and date in the bios too when your at it.
Do you take the pc of the power completely after shut down? Out of the socket or flip the switch on the psu etc.

New battery will arrive tomorrow.
"Also save the optimal default settings after that.Take a look at the time and date in the bios too when your at it." I'm not quite sure what you mean by that. I'll just assume that you mean the bios settings. Everytime the Computer starts itself with the routine i described, the clock is wrong.
For the Power: i did both, with the sae result. When i plug it it or flip the switch again and power the Computer on again, it starts, turns off immediately, starts again and then gets me to the bios recovery.

Never mind about taking the pc completely of the power,didn;t look right and this should not be happening then,

Just replace the battery,go into the bios and search for the optimal default settings and save these via F10+Y.

.

You fixed that?
Set everything to the default values too? Except the following ...

it has probably nothing to do with your problems,but i saw the next,

which means your ram isn't running at it's rated speed=1600mhz,you could enable the xmp settings in the bios to get it at that speed.

okay thanks.

What i also noticed is that if i restart the computer and then shut it down, the whole problem won't happen.
Maybe that will lead to the right path.
