Need help ASAP!! Replacing CPU

[Augustine1]

Hello,

I replaced my Ryzen 5 2600 with the new Ryzen 7 3700x. Upon replacing the chip, the pc did not boot. To no alarm I figured I needed to update bios. I replaced the 3700x with my old 2600 and the pc did not boot, just black screen with no boot media. I rebooted and went to bios, moved my M.2 with my OS on it to first priority, and the PC still goes to the same black screen, no bootable media. If I use my other hard drive, it blue screens as no OS is on there. What is wrong???!?!??!

I don't know, don't have AMD CPU.

Did you reset the BIOS?

Clarify which of the "boot" you describe is actually "post" (reaching the bios) or "boot" (reaching the OS)

Is posting, is not booting to OS!

Any damage to the CPU's or socket? Any paste or bent pins?

Prior to swap - was working fine, post, boot to OS, etc

after swap - no post

after reswap (back to original chip) - post, no boot. 

 

I have my M.2 that has the OS on it in 1st boot priority, but it is saying reboot and select proper boot device (black screen)!

Nope, it is fine! it's recognizing the CPU fine as well

Does the BIOS recognize a UEFI partition on the drive?

Also, try doing a BIOS reset with the jumpers on your motherboard.

It does not show a UEFI on the M2 drive in BIOS

Damage to the drive then?

Id suggest a good 'ol cmos reset by removing battery and/or clr cmos jumper (power off first) s churl already suggested

 

Something in bios else likely got "confused" with the cpu swaps, and "thinks" its okay (posting) but somewhere something isnt.

 

Hope it helps!

Okay, that's why it's not booting. It sees the drive just fine, but the UEFI partition (aka the bootable potion of the drive) is not showing up to the computer. Try disabling "legacy mode" in your BIOS's boot settings and see if that changes anything. If you updated/reset your BIOS this setting could've gotten changed.

Also, try changing your secure boot settings

Should not be, the computer booted, then I swapped CPUs, the drive was never touched. Has remained mounted and secured

I turned off legacy mode but then it removes the drive from the priority list. There is no other bootable drive

Actually, I just went in and got it. For some reason the drive was not appearing on the priority list anywhere. But when I went into settings and looked at the drop down menu, it (w/ uefi) was able to be added into the priority loop. Thanks!!!!!

Looks like you're not the only one with this issue when switching to 3rd gen. Have you tried putting your old CPU back in to see if it is just a compatibility issue with the new CPU?

I guess that'd be an important setting, hah! Glad you got it going

Yea thanks, again, it was weird how it was not showing up at all. It's running with the 2600, now I just need to update BIOS for the 3700x support. Thanks again
