Graphic problem after changing cpu

Hi guys,

First of all sorry for my english ? but i need some help

I have asus prime x370 PRO motherboard with ryzen 3 1200. I bought new cpu (ryzen 7 3800x) i just swap this 2 CPUs but had to reisntall gpu and rams becouse of space to work with fan. Now after “succes” swap i turned the pc on but fans (cpu and case fans) started to spin but graphic no. What can be problem i cant get any live from that gpu and i kmow it must be good. Shoud it be that cpu is not compatible with motherboard ? Or what could couse this type of problem. Thanks for tips

Update (01/03/2022)

Your motherboard will accept this CPU but what BIOS version do you have? The BIOS may not recognise the new CPU.

The ASUS PRIME X370-PRO board requires BIOS version 4801, or higher, for the Ryzen 7 3800X CPU. The current version is 5606. If this fixes it then an outdated BIOS was the problem.

You did not mention which graphics card you have. Did you remember to connect the 6-pin or 8-pin PCI-E power connector from the power supply to your graphics card? Make sure the card is seated properly on the motherboard. Take a close look at the motherboard to see if any other connections are not secure.

It might also be a good idea to take out the CMOS’s silver coin battery to reset the BIOS. Unplug mains power cable and press power on button to discharge any residual electricity. Look at your manual for the CMOS/RTC RAM jumper pins. They suggest using a screw driver to short the pins if only two or use the jumper, as shown, when three pins.

The following will only work if you can get to the initial boot screen before Windows loads but if you get to this point you can try booting up in Safe Mode which will load the generic Windows graphics driver. If this works then you know it is a driver problem.

Any how try the above and get back to us in case if it still doesn’t boot properly.

Update: Same topic but different AMD motherboard. ASUS Prime 550M-K ARGB CSM and a AM4 2200G CPU. This needed the opposite to work - it had the latest BOIS/UEFI version 3607 but needed it flashed to the earlier v3205. Why? With v3404 1. Update AGESA version to ComboV2PI 1.2.0.B

2. Update AMD 5000/3000 Series CPU

the older 2200G wasn't seen and the front light flashed rapidly falsely indicating a damaged CPU. Trying it on another motherboard confirmed that the CPU was fine.

Fortunately ASUS allows flashing with an earlier BIOS unlike ASRock which doesn't.

@w4ntyy

If I understood correctly you updated the BIOS with the Ryzen 3 1200 but when you put the Ryzen 7 3800x back in you got the 3 beeps?

Is that correct?

의

@aactech Yes but its fixed just be reseating rams and CMOS battery. thats was no big deal. But there is 1 thing that after a pc turned on everything was laggy like mouse etc.. i updated drivers, restart few times and it seems to be good now.

@w4ntyy Good to hear.

Hi,

Are you connecting the HDMI display cable to the port on the motherboard or to the port on the graphics card?


If you’re currently connecting to the graphics card, I’d recommend switching that cable over to the motherboard and seeing if you get a picture on your monitor. If you do get a picture while connected to the motherboard, I’d recommend updating the graphics card’s driver.

Since you upgraded the processor, there may be an incompatibility of the current driver and the new processor. So you can temporarily get a picture by connecting directly to the motherboard to upgrade the driver and then revert to connecting HDMI to the graphics card.

Hi Michael,

Neither the Ryzen 3 1200 nor the Ryzen 7 3800x have integrated graphics so that wouldn't be Marian's problem.
