Hello, I'm trying to help a friend troubleshoot his new computer:
asus z170 deluxe
i5-7400
rx580
16gb ram dual channel
intel sata ssd (boot drive)
samsung sata ssd (brand new, no data)
1tb hdd (old storage)
I put the whole thing together, the mobo's bios had never been updated since bought in 2016. I went to boot up the system and the post code error 62 (not b2) showed up and the vga led turned on and stayed lit. I tried clearing the cmos, and removing the gpu/having 1 stick of ram. I still can't figure out how to update the bios correctly because I can't use the EZ tuning stuff or the bios.
 


The board does feature the Flashback. No need for CPU to flash the BIOS. If not sure how to, post back.
 


By the way, what do you mean by "it didn't like the ram until i shifted it to the b slots" ?
