Hello guys,
It's been almost a month that I started to have a strange problem where my pc won't turn on again after being in sleep mode for a long period.
If I manually test the sleep mode it has no problem posting and booting back to the os but when I leave my pc on for a while, 4/5 of the times the boot stuck at VGA and wont turn on again.
Morover, when this happens, i have to keep turning it on-off a few times before it finally boots normally into windows, what do you think it's happening and what can be the reason behind this behaviour?
CPU: 3700x stock
Mobo: b550m mortar (already tried 2 different bios version)
Gpu: 6800xt (already tried at least 2 driver releases)

PSU: make, model, wattage, age, condition?

= = = =

Power down, unplug, open the case.

Clean out dust and debris.

Verify by sight and feel that all cards, connectors, RAM, and jumpers are fully and firmly in place.

Run the built in Windows troubleshooters. The trouble shooters may find and fix something.

Likewise: "sfc /scannow" and "dism".

Corsair rm750i, relatively new, only a few yers.
The pc is perfectly stable under any kind of load so I will exclude it.
Also the windows installation is kinda fresh, I double-checked with both sfc and dism but anything was fine :c

View the "technical details" for those Critical Event errors and Warnings in Reliability History. What error code number(s) are listed?

Also look in Event Viewer for errors and error information. Event Viewer is not as user friendly but could provide some additional information.

= = = =

Next turn off all power savers and sleep modes for a few days.

Determine if the problem ends and/or the error code and warning codes change.

The PC/PSU may be stable under any load; however, the process of waking up etc. may impose a pattern that is not necessarily stable or otherwise becomes some "perfect storm" of events that cause the problem.

Going on a few years in age makes, in my mind, the PSU certainly suspect. Could be nearing its designed in EOL (End of Life).

If you have a multi-meter and know how to use you can do some testing on the PSU.

Not a full test as the PSU is not under load. Any voltages out of tolerance would be indicative of a failing or faltering PSU.
