Hi. I am trying to update my BIOS to PO3.A3 so that I can update to an I7-3770 chip which I already purchased. Running Windows7. The instructions just say to click the Win_dos.bat icon and it will flash but it doesn't work from within windows. There is an exe file as well AFUWINx64.exe file which I attempted and that didnt' do anything. I tried booting into safe mode command prompt and installing from DOS with the BIOS_DOS.bat and got an error that it wasnt for 64 bit OS. I then tried to do the Win_dos.bat from command prompt and that gave a cannot run driver error. I cant find any solutions online and do not know what else to try. Any other ideas? Also, the two memory card slots closest to the CPU stopped working when I tried to upgrade my memory. I'm not sure what happened as Ive changed memory many times in the past, power was unplugged and I know how to insert the cards. Is there any chance that the BIOS flash may fix this? Thanks in advance.
