Hi, I recently purchased a 5800x for my gaming build and replaced my 2600x with it.
My rig was running fine then threw a blue screen error and now it won’t post. Keeps showing white led (VGA) error. Since it did this after replacing my cpu I swapped my 2600x back in and it started up fine. The bios is updated to latest version and CMOS was reset. I don’t know if it’s the CPU or a comparability issue going on. Process of elimination is point

How long did it run correctly?

Did you reset the CMOS by jumper while power was unplugged from the wall?

BIOS version is
Version 5003 ?

Check all components if plugged in correctly and tightly. unplug all and replug

It ran for about 6 hours perfectly fine, I updated bios from 4902 to 5003 then flash backed to 4801 because it’s still giving VGA light. I’ve swapped the cpus out about 3 times now and every time my 2600x goes in it works fine. I pulled CMOS battery and jumped from positive to negative for about 10 seconds. I’ve been trying to find the common denominator and it seems to be the CPU but I don’t understand how it would throw a VGA error

I’ve even gone as far as to freshly install drivers for the graphics card. I was even able to run a benchmark on UserBenchmark and was shown that the components were performing above average

The CPU controls the PCIe lanes, so maybe there is a problem with the CPU recognizing the correct settings or anything disturbing it. Might be a defect as well. You might RMA the CPU and check with another CPU, if it´s getting the same issue.

update to 5003 again to be sure it´s not a CMOS reset error after updating. After the update reset the BIOS by jumper

are you 100% sure that you updated with the correct BIOS? How did you update the BIOS?
the
ASUS ROG STRIX B450-F GAMING II is also available (update shouldn´t work cause it´s the false one hopefully)


maybe: replace the cmos battery

I tried that solution and to no avail, I’m going to return the cpu and just upgrade to the 5900x like I should have. Do you think it could be a power issue?
