Problem with CPU and boot error indicator
Problem with CPU and boot error indicator
Experiencing some problems after upgrading my board and CPU, B450 Tomohawk MAX + R7 5800x to B650 Elite AX V2 + R7 9800x3D.
Updated the BIOS using qflash+, took about five minutes; the flashing lights changed speed and then the PSU powered off as expected. I think the update went through correctly.
After assembling everything, I’m encountering a boot and CPU error light, no image appears on the monitor, fans are spinning but the CPU fan seems to restart after some time.
Relevant notes:
My new board features an 8-pin CPU power socket (only one in use) with a nearby 4-pin socket. According to online sources, I should only need the 8-pin unless overclocking, but I’m curious if this matters.
I tried using qflash+ a few hours before the supposed successful BIOS update, without renaming the file, so I had to rebuild my old system to do that.
During the “successful” BIOS update, the CPU error light was on, but I thought it was because I didn’t have a CPU installed—this isn’t necessary when using qflash.
I spent the whole day trying to fix this, so any advice would be greatly appreciated!
It seems you've upgraded your system from the B450 to the B650. The current setup includes the B450 Tomohawk MAX with an R7 5800x, upgraded to the B650 Elite AX V2 paired with an R7 9800x3D.

New board and cpu, used qflash to update bios, had cpu and boot error light that then went away next boot up, became dram error light that disappeared and is now VGA error light.
Gpu fans are spinning, just like all other fans, tried different ports on both gpu and monitor, monitor picks up some form of data then says theres nothing display and returns to standby, tried internal graphics and its the same.
I don’t know what to do next?

Did you reset the CMOS after confirming the BIOS flashing was successful? Regarding the rams, which slots are being populated on the board? For cooling the processor, without a discrete GPU in your setup, you should still be able to rely on the integrated graphics.
Keep it simple, stick to one thread unless you're aiming for chaos.
Apologies,
• I didn’t follow a video guide and it didn’t mention clearing anything, so I’m not sure if that’s necessary.
• Rams are located in slots 2 and 4.
• The CPU cooler is the “Noctua NH-U12A chromax.black 60.09 CFM CPU Cooler.”
• Should I remove my GPU to use the integrated graphics?
Clear the CMOS by unplugging from the wall and screen, take out the CMOS battery, hold the power button for 30 seconds to remove any leftover power, then put the battery back after about half an hour.
Are slots A2 and B2 correct? They are marked on the motherboard's PCB next to the RAM slots.
Without securing the CPU cooler, just place it gently on the CPU IHS. If you built the system inside a case, you'll need to position it on its side. Too much pressure might prevent the pins from connecting properly.
It’s better to take out the separate GPU and connect it to the integrated GPU first, then restart the build.
You need to buy a new battery or replace it completely.
Yes, please.
Slots A2 and B2.
I plan to unscrew the CPU cooler and remove the GPU to use the integrated graphics; do you think the CPU is still having problems even though the error light has stopped?
Also, the error lights indicate priority order: CPU first, then RAM, VGA, BOOT. So RAM and CPU are clear.
