yeah i think flashing work fine..i took your advice (read manual) about BIOS
i tried recover BIOS back to original setting (update F1) using USB and it works..
is there any change BIOS ver.F5 not compatible to my MB?
anyway thank you the advice.
I think that you simply had a bad flash. I'd download the latest BIOS file again to a USB drive and flash from the BIOS utility instead of Windows. Just make sure that you select the correct BIOS for your motherboard. On the other hand, if there's nothing that the latest version fixes for your system, then don't flash it.
