To begin troubleshooting, we ask you to test your system outside of the chassis. Please place your motherboard on a table, on a non-conductive material, and try booting it with only basic hardware attached. This is to ensure there are no grounding issues with the system case.
Also, if possible, try using a different operating system, to confirm if the problem continues to occur.
Thank you for your help. Grounding is not problem. I removed a battery from the board on few minutes and insert back. Problem (error) has not occured and everything is working. Windows is starting without problem.
I've noticed that the latest version of BIOS (128 from 28.8.2011) is not on your website today. Some problem with this version ?
