Solved Monitor Enters Power Saving Mode or PC Restarts During Gaming (not repost, same issue!)

The other thread was closed because OP didn't provide additional information but it seems like the exact same issue I have been experiencing for about a month now. Boot up a game, random chance while playing for the entire computer to hang and my monitors go into power saver mode indefinitely; sometimes my pc will reboot itself but that's even rarer. Thing is it's highly inconsistent, some days I can go without a single issue but the next day will have crashes anytime I play more than 5 minutes. The only things I can at this point say for certain are that there is no problem with normal web browsing and that it has never crashed while I was on comms in discord. The latter is of course probably nothing more than a fluke but I can weirdly play GuildWars2 with my friends for hours without a single problem, then try to play The Sims 4 later that night and keep getting hangups.

Updated graphics drivers, windows, and was advised to run a memtest but no errors were found. Event viewer rarely has errors for anything apart from when I have to force shutdown after a hang. No signs of overheating.

What thread showing that you have only posted once here just joining the forum today?

You also need to supply the make and model of the PSU.

Apologies, this is the thread I was referring to. I was very happy to see someone else had posted a similar issues and was hoping it'd be common enough to get pointed in the right direction for a fix.

I believe this is my PSU: 750 Watt 80 PLUS Gold Certified Power Supply

This is mostly a prebuilt pc with only the GPU being changed.

Is this something that just started happening or after the GPU was changed?
See if uninstalling the GPU drivers using DDU and then see if that helps.

Display Driver Uninstaller (DDU) download version 18.0.7.6

Download Display Driver Uninstaller (DDU) - Remove AMD/NVIDIA/INTEL Graphics Drivers Cleanly - DDU is a driver removal utility that helps you completely uninstall AMD/NVIDIA graphics card drivers and packages from your system, leaving no leftovers behind, including registry keys, folders, files...

See how the system acts before installing the drivers for the GPU.

I'm afraid I'm gonna be very difficult and say I am not at all comfortable with moving things around in my pc and there's no way to see that side of my PSU without removing it thanks to my case (at least none that I can see). If not having that information makes this impossible to diagnose, I apologize for wasting your time and will see about bringing it in to a shop. I would just really like to cover all my bases before I get to that point.

The pc was a gift back in 2020 but I think this is it. It was listed on ebay brand new without a GPU. I bought my GPU in 2019 after my previous one blew a fan. My issues have been happening for about a month at this point.

I have already used DDU to uninstall my drivers but I didn't do any testing without them. I was advised to uninstall and reinstall without internet connection and accessing Origin games without internet doesn't always work for me.

One thing I saw mentioned for similar issues is that it was probably bad VRAM and to try underclocking the GPU. Asked a friend to walk me through that and while my game froze once and was suddenly maxing out my memory usage, I could still close it in task manager and reload without any problems occurring for over an hour. Problem is since my issues are really inconsistent, I can't try multiple things at once because it can run fine for one day then crash the next.

Well, it does seem like the last test did somewhat solve the issue, or at least give me a possible culprit. Underclocking my GPU has stopped full system hangups and crashes though it came close to one earlier. My game completely froze and my audio started glitching for a moment like when it's about to crash, but luckily only the game stayed frozen and the system was fine enough for me to get task manager open and close the program. It's only been a few days so I'm not 100% certain at this point, but it does look like bad VRAM is the problem. My understanding is this means I have a dying GPU and the only fix is to replace it?

Alas as stated before I'm just not comfortable dismantling my case enough to get at the side with the information on the PSU (it's completely covered on all but one side and that has nothing on it). I will keep this in mind if I'm able to have it properly looked at in the future. Hopefully at the very least my floundering points someone else in the right direction if they ever have this issue.

I think for now I'm as good as I can get. At the very least thank you for hearing out my issue!
