The problem from the start, of 8 months. Where were rare, and are often already got irritating. About three weeks after a few weeks I started to test components. The problem occurs if the reset button is not pressed I noticed lately, just reboot after a few hours or a day. Random As I said in earlier. Appear two to three times a day, and at intervals of several days. Singing days are all functioning normally.
In Windows (Event Viewer) no errors, no black screens, no crash.
Power supply is now installed in another system. Old system working without any problem.I tried everything.
I want to buy an SSD and because of this boot loop can not.
After discussion with Gigabyte support told me to send the motherboard in service for more checks.
Excuse my English.
Perhaps they suspect and motherboard.
Thanks for the advice and support.
