Thank you Judas! I used different browser for AMD chipset and it worked . Still puzzled why older version of chipset drivers was able to unzip but newest not. Oh well, just one of these things. Could not find the CSM/Legacy mode in UEFI... I was about to switch to ULTRA FAST boot but got scared as the message said that it boots so fast that the only way to get to UEFI is to clear CMOS or run Restart to UEFI utility in Windows. Let's say I enable it. How do I go to UEFI if needed that from Windows? Will check different benchmarks. I will also have a question on cooler. Coming tomorrow. be quiet! DARK ROCK 3 SilentWings CPU Cooler 190W TDP Will it be much better than stock one? Thank you one more time for your help and patience with me.
