Hi Fzeven Yes i have, i have clear cmos and close the pins for over 20 secs, cmos was resetted (sorry for my bad english) see on boot screen my logo show comes back and i have no bootscreen but nothing change, hang after bootbeep The good thing first: After over 2 hours reboot and many many combinations of F1 f2 ALT-F1 my mobo comes into Bios Checksum Error and Bios recovery started, now it runs with the old f3a version. The bad thing i dont know which combination work i try so many and i find no information in inet and the manual for the next try. Greets Wirks
