Hi all,

I recently built my first system:

- MSI MAG TOMAHAWK X570 Wifi
- Gigabyte RTX3080 Vision OC
- Corsair Vengeance RGB PRO DDR4 (2x16gb at 3600mhz)
- Ryzen 5800x
- Corsair RM850x PSU
- Booting from a WD black 850 500gb nvme
- 1TB sabrent SSD
- 1TB hard drive

All is running well apart from the fact that when I shutdown my system and boot it back up the next day the VGA debug LED on the motherboard lights up and I get no output (no error code or anything). If I then power down the system and boot it back up it boots fine. I have tried removing and reinserting the GPU and actually recently swapped out the PSU from a gigabyte P850GM ot a corsair RM850x. I have updated to the lasted version of the BIOS for my motherboard and updated the vBIOS on my graphics card and still the problem continues. I have also tried switching on my screen prior to booting up but that didn't solve the issue. I was wondering if anyone had any idea what is going on?

Thanks
 
Which BIOS version? The latest for that motherboard is actually a beta BIOS, I use 7C84v15 which is the next one down in the BIOS latest and is a stable release. I have the same motherboad so I will reboot mine now and check for any debug LED's.

You say you power it down and boot it up the next day you get the LED's, but then you say if you power it down and boot it up it's fine?

I'm a tad confused there.

Have you tried another GPU if you have one lying around? And just to double check it is the top most PCIe slot?

Thanks for the reply.

Sorry let me clarify a little. So if I shut down the PC and boot it up within a couple of hours it boots fine. However, if I shut it down and leave it for let's say 6 hours or so, the next time it boots it gives me the VGA debug LED error. I then power it down by holding the power button and turn it back on and it boots fine. I hope that is a little clearer. In terms of bios version I have tried a few in an attempt to fix the issue as I have been trying to address it since I built the system in December. I have used 7C84v15 and still had the issue and I updated to the most recent beta (7C84v163(Beta version)) a couple of days ago to see if that would help but it didn't. Also, it is the top PCIe slot and unfortunately I don't have a spare GPU to hand to try.
 
That's clearer thanks.

Have you tried running Display Driver Uninstaller, doing a "clean and restart" option and redownloading the latest drivers from Nvidia? Just going through the simple steps first. Might be worth a go.

No, I didn't think to try that. I will give it a go. Unfortunately, because of the nature of the error I have to leave the PC off overnight to see if it fixes the issue the next day. I will post back with the result. Thanks for the help, this has been driving me insane!
 
no overclock on CPU ? Ram running at default 2133hz just to double check core system ?

checking with spare GPU would be handy but not always possible .

might have to check the power leads with the GPU as Gigabyte UK were taking in the cards and changing the connections - could cause an error but normally they just didn't boot up at all.

using one power lead per 8 pin connector ? always good practice

Thanks for the reply.

No overclock on the CPU but I did enable XMP, so the RAM is running at its rated 3600hz. I did replace the power supply and all the cables within it recently and the issue persisted but if I understood correctly, you are suggesting the power connector on the GPU itself might be an issue? Yep, I am using one power lead per 8 pin connector. In desperation I even added the the extra 4 pin to the motherboard but it didn't help (just in case it is relevant).

Change to 2 single 8 pin cables to the gpu as mentioned above.

early models weren't wired up as stable/weak point with gaming oc

I have done this today and will know by tomorrow if it solves the issue.

I checked my serial number and it begins with SN2047 which according to the post most-likely indicates it is not affected by the pin issues. However, I will visually inspect the pins to see if I can spot anything strange (though I am not sure I will know exactly what I am looking at).
 
Have you tried after clearing CMOS including removing battery. Changing battery although would seem strange with age of board, do you turn off PSU when not using?
Try turning off fast boot in bios and windows (might also be a fast shutdown on windoes settings -or I could be imagining it), this has been known to cause issues before.

So I have now done this but unfortunately it did not solve the issue. Any other suggestions?

No I have no tried clearing CMOS but will try it this weekend. I don't turn off the PSU when it is not in use. I have disabled fast boot in windows but I didn't realise it was also in the bios so will do that also and report back. Thanks

latest chipset drivers?

Yep, made sure the latest drivers are installed. Still having the same issue but I will clear CMOS today and see how it boots tomorrow. This motherboard's bios doesn't appear to have a fast boot option but I have it disabled in windows with no effect.

Cleared CMOS but still the issue persists. Any other ideas? Thanks
