Sudden VGA light on a previously working PC

[dapetish]

Hi,

Today an odd thing has happened to my PC. I was using it as per usual the whole day, turned it off (no updates installed) and when I've turned it on again no image was displayed on my monitors. I've checked the MoBo to see if a debug light was on, and yes, the VGA light was on.

My config: MSI B450 TOMAHAWK ( with the latest non-beta bios installed last week ) R7 2700 16 GB RAM ( 2 x 8 gb placed in the 2 & 4 slots) RTX 2060 ( drivers from 9th or 10 of May 2024)

What I've tried to do:

• reseat and check the GPU connections

• reseat and check the RAM

• reseat the CPU

• try to boot the PC with only one stick of RAM in

• reseat the CMOS battery

• reset the BIOS via the motherboard

Please note that I've been using this build for several years now and have never encountered an issue like that.

Would anyone have any idea / suggestions of what might be the issue / fix in my case?

Do you have another GPU you could try?

I'll planning to go to a friend house to put my gpu in his pc to check if the gpu is the issue

Great, update us on the result

I've done that and it has booted on his system with no errors.

I believe then that it has to be CPU/RAM/MoBo related, what do you think?

Yes, could you borrow your friends RAM to eliminate that?

Sadly I can't, but as I've said, I've tried to reseat and try to boot with different sticks in different slots and got the same issue back

Also, in the case of a faulty RAM, shouldn't the DRAM light turn on instead of the VGA? ..but I guess the same mechanism would apply if it was a cpu issue..

Yeah sorry my bad, I forgot it was a VGA issue, went to basic troubleshooting.

 

Yeah, it would appear to be either a motherboard or cpu. Any chance you could try either of them parts individually?

Also a no sadly

Would there be any troubleshooting things before resorting to that step?

Have you tested the GPU in the lower/secondary PCIe x16 slot?

Not that I can think of, no

 

You know the motherboard is clearly getting power, so the next step after that normally is to try it with known working components

Yeah, I'm getting the same issue
