[SOLVED] Computer keeps going to sleep or shutting down while active

[chadmikeh]

So a couple months ago now my computer started going to sleep in the middle of a game, video or anything else I might have been doing. I'm at wits end trying to even troubleshoot what might be the problem. As of now I've upgraded my computer with a brand new MoBo, CPU, and memory, I've hooked up a different working PSU and I've reinstalled Win10 multiple times on different drives. I thought I was getting close to finding the problem but since installing win7 yesterday, but with no luck, I'm down to checking the GPU as the possible culprit. I'm quickly getting out of my depth and I've decided I need to start finding help in other ways, so any help on this matter will be appreciated. With that out of the way:

THE PROBLEM: My computer keeps going to sleep suddenly while in use (or not in use) .
occasionally it will actually shut down or crash and require a restart but for the most part it just randomly goes to sleep and wakes up with a mouse input only to go to sleep a few minutes after. I looked at and replaced all the thermal paste in my computer (it needed it) including the CPU, GPU and, the heatsinks for the north and southbridge on the old MoBo, the latter of which I think made the problem worse since afterwards it wouldn't stay awake long enough to log in afterwards (the new MoBo is fine though). No problems with staying awake in the BIOS but as soon as I load an OS the clock starts ticking.

MY ATTEMPTS: I've tried burning it, shredding it, even burying it... no jk!
but I have tried replacing almost every vital part in my build except the GPU (I may be able to get my hands on a working GPU to test and I will update if needed). The MoBo, CPU and RAM are all brand new and I've hooked up a working PSU to rule that possibility but the problem persists. I have reinstalled Win10 multiple times on different drives and even tried Win7 with no luck. I've updated the GPU drivers and still get the problem. The case is cleaner than it has been in years and all the thermal paste is fresh.

And now the part you've been waiting for...

I've included model numbers and the links through which they were purchased, and I can include the old parts if needed!

So I feel like this was a lot to say "it's probably my graphics card" but I would like to avoid replacing it for the time being if possible. My apologies for all the repeated info but I want to be as thorough as possible and again any help with this will be very appreciated!

That GPU is pretty underpowered for that system. Even without problems like this, it's 4 generations old and it's probably due for an upgrade. A 3060 Ti would be a good choice.

Well I don't know if this confirms it but based on what you said I did a search and found a post that mentions him turning off his monitors, so I tried turning on my comp but leaving the monitors off and it definitely stays on longer, probably going to sleep because its not logged in.

So if that's the case and it is just my old gpu is there someway I can make it usable for the time being. Is there some setting I can forego, knowing that my GPU is going bad that will make it not shut off on me or would overclocking be something I could look into right now?

I'd first disable all the drive/monitor/sleep/ power management settings...

As for actual crashes, not every Ryzen 2700X is 100% stable at 3200 MHz RAM clocks on every mainboard....; test for stability at lower clock speeds like 2666, 2933, etc.., first

I'll definitely try this!

The CPU says 2933 and the board is 3200 so would 2933 be the sweet spot?
