Hello to everyone and Happy new Year!

After update my Maximus XI Hero to new 1401 BIOS I had instability problems with PC (BSOD). Returned to 1302 - again I have BSOD every time on boot screen.

I can't go to windows. Checked everyting (another PSU, memory, M.2, SSD, HDD, GPU, cooling)!!! Tried 1401, 1302, 1105, 1005 and 0905 on default BIOS settings without luck.

I have BSOD with Windows installation USB and clean SSD prepared for installation. Nothing, BSOD every time!

Shortly I menaged to go in Windows only if underclock CPU below maximum rated speed. Intel diagnostic tool reported that CPU is OK and passed everything (underclocked). But every BSOD is related to whea, memory menagment etc. That is strange. After reset I can't go in WIndows again (BSOD) with that underclock. I had to underclock CPU again to go in windows (more than last time). And everytime after reset more and more underclock.

Thank you ASUS for bricking my MB or CPU for new year! Maybe bricked MB and CPU together. Who knows?!
