Small-Scale Question Sunday for August 27, 2023

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Posted here for new eyeballs:

For the past few months, my pc has been consistently crashing under heavy load, in graphically demanding games like Escape from Tarkov, Warhammer 3 etc. In normal use and less intensive games like Rimworld, no issues.

After about 15-20 min of gameplay, I get a full crash to a black screen with the pc powered off, and it refuses to post for several minutes regardless of what I do, at which point it often restarts on its own. The American Megatrends screen doesn't usually show up unless I cycle power, at which point it doesn't tell me anything useful either. (I had a similar issue around 5 years ago, but that was almost certainly CPU thermals, since the American Megatrends screen called out CPU overheating, and I've changed CPUs since then and don't get the same error)

The crash seems to be so total and abrupt that I can't find any useful logs to figure out wtf is going on.

I've run CPU and GPU stress tests on OCCT and furmark, and they only seem to cause issues unreliably.

It seems thermally related, since the problem is less severe when the AC is running, but unfortunately the AC is currently on the fritz exacerbating the issue, but fixing the AC isnt really a definitive solution is it?

I noticed >85° C temps on my Ryzen 5600x, so I changed the thermal paste just a few days back, and while temps dropped by 5-10 degrees, the crashing hasn't abated.

GPU temps hover in the 50s-60s range in Tarkov, which seems quite reasonable. It's a 3070 for what that's worth.

The other potential culprit is my geriatric 600w power supply, over 10 years old at this point, but why would it be thermally related?

I'm not running any OCs, and I've maxxed out my fan curves to help, not that it's doing much. My case has two extra blowers, and I even took off the sides to help with airflow.

Anyone have any idea as to how I can figure out what exactly is wrong? I can't really afford to replace my GPU, but I could consider buying a new PSU if need be.

This issue didn't plague me when I first built this current setup with the same components, but it's been several months and I'm losing my mind :(

What I've tried:

  1. Switching GPUs with my brother's pc. Couldn't reproduce crashing.

  2. Dusting pc

  3. Repasting thermal paste

  4. Checking for any OC (none)

  5. Stress tests, which are unable to reliably cause crashes while games can.

Just post on Toms Hardware man.

I'll keep that in mind, but I'm sure there are plenty of local nerds here too!

Most of the advice you got here is much worse than what youd get on Toms.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
