As above my mrs has inherited my old pc, ryzen5 3600 with sapphire rx 5700 xt pulse, now this issue also happened for me and i could not figure out what was causing it.

You can close the pc down normally, go back to it next day turn it on and the monitor goes into sleep mode as its not getting a signal, turn the pc off by holding power button, turn it back on and it boots fine. Sometimes i have noticed that after this event the graphics drivers have been reset and i have to reload my fan curves and settings.

I have taken ram out and reseated it, same with gpu. Everything is stock settings. i have removed the cmos battery but did not noticed anything different when i popped it back in. Temps are good .

Has anyone any idea's whats causing this to happen.

oh mobo is tomahawk b450 max and it is not on the latest bios as i was getting blue screens, i am on version 7C02v32 which seems the most stable for me, there are 7 more ahead on this one. It does have latest chipset drivers.

thanks
 
Does cycling the monitor inputs restore it? If so, probably the cable, as said above ^^ especially if it's converting the signal
 
Just an update i have had my head in the pc and noticed 4 of the smallest trouble shooting leds on the edge of the mobo, turn's out when the issue above happens i have a solid led for cpu, according to the manual it means cpu not detected or fail. Everything is 18mth old.

anyone able to give me some pointers?
 
Do you have the heatsink mounted too tightly? Just take it off and take the CPU out and clean both then refit.

Don't think so, i have the dark rock pro 4 and i do not recall this happening way back when i built the pc

Not while it is in this state, its just hung there, i have to press power off then power on and it boots just fine
 
I am having a very similar issue, with the main difference being that I get the vga LED debug light rather than CPU. I have a msi X570 Tomahawk wifi, a ryzen 5800x and a gigabyte RTX3080 vision OC (https://forums.overclockers.co.uk/t...vga-debug-light.18926822/page-2#post-34779840). Not sure this helps you but I have so far replaced the graphics card with another and replaced the power supply, neither of these steps fixed the issue. Also, I sent the board back to overclockers where they attempted to recreate the issue and they managed to boot it fine (even after leaving it overnight). I am now getting a little desperate and looking to see if it is a RAM compatibility issue (not sure how this would give me a VGA debug light).

@MadNuke what was the outcome? I'm having the same issue
 
Might be a completely different issue but I saw a VGA debug light on a b450 tomahawk a while back which was actually caused by an m.2 nvme ssd (needed a bios update for the mobo to realise what it was). Wonder if the vga light might sometimes actually relate to all pcie devices - could try unplugging any nvme drives or other pcie cards etc?

I finally discovered the issue to be with my boot nvme ssd which was an SN850 from western digital. I tried two other nvme ssd's and both stopped the issue from occurring. I am currently using a Sabrent Rocket and I have never had another failed boot. By the time I had discovered it was the SSD I had already tried different RAM, power supply, graphics card and even sent the motherboard back to OC where they found no issue. Hope this helps.

Thanks very much. I also have that drive.
I've got a new mobo coming today, but will keep that in mind thanks. My issue is that I get the VGA debug light when the graphics card is in the top PCI slot. My drive is in the top M2 slot so maybe it's the same problem.

It is interesting you should mention the SSD being it the top slot. I originally had mine in that slot but found that it would sometimes be undetected during boot but a restart would then fix the issue. Moving it to the bottom slot seemed to fix this problem but then the VGA debug light issue started occurring, where as you described leaving the PC off for at least about 4 hours would mean it would then fail to boot with the VGA debug light coming on but then a restart would allow it to boot. I never tried my GPU on the second slot as I didn't want to use a slot with less PCIe lanes (not that I know much about this). Hope the new mobo helps otherwise I would suggest trying a different SSD based on my experience.
