Question about Gaming PC upgrading and crash diagnosis. (self.pcbuilding)

I have 2 questions that may or may not be related:

  1. My gaming PC periodically has full system crashes while I'm playing some games. I've tried looking at crash reports but I couldn't really figure out what was different from looking at them. I've seen it suggested that it could be overheating, although it's kind of hard to tell since the temp range when I check isn't that high, but I do feel a lot of heat coming off the machine when I stick my hand over the vent and I hear the fans working hard when I'm playing some games.

  2. I was thinking that it might be worth it to try to upgrade some parts to maybe alleviate one possible source of issues. So what I'm wondering is what the best approach would be. For example would getting a better graphics card make it work less hard and produce less heat? Or does a more powerful card just produce more heat? How much can I reasonable upgrade cooling systems given a fixed amount of space in the case? It's been a while since I've manually swapped out parts. Last 2 PC I opted for just buying pre-made although in the past I built one. The one I have now is an Alienware Aurora R11 from a few years ago and it's got an RTX 2070 Super for a graphics card. Does it make sense to try to upgrade it? If so, is it worth going for the newest series or would it be fine/better for my purposes to go to the 30 series?

Are you sure it's heat? Heat could be the culprit, but unless you're regularly running hot (think 90C+), it's probably not heat. Even 75°C would be normal for a graphics card, and "feeling a lot of heat" and hearing your fans when playing something graphically intensive would be expected at those temps.

Three common causes of crashing that aren't heat-related:

  • Bad/corrupted driver
  • RAM going bad
  • PSU going bad

Try a fresh driver install. How old is your RAM or PSU? Try playing games with your RAM set at JDEC speeds (turn off XMP). Have you checked for BIOS updates?

If you're thinking it's heat: when was the last time you changed the thermal paste on your GPU?

For your second question, I'm not actually sure, but I would think that a more powerful card should produce less heat overall for the same workload (in general), since the equivalent processing power of older hardware has ideally been crammed into a smaller footprint.

Thanks for the response. For now I tried updating my BIOS and I'll work my way down the more difficult troubleshooting steps as I have time.

As for age of RAM/PSU, they all came with the PC which I got sometime in 2020. Do they tend to go bad over time if nothing else damages them? Short of swapping them out, how can I tell if they're the cause of the issues?

Also with the thermal paste, is that something I'm meant to regularly change or just if I suspect there is an overheating issue?

Copy and paste your crash log into ChatGPT, it will tell you what it means.

My guess would be power supply issue. Post your components and we can help further. And how old those components are.

I just upgraded my computer, I also have a 2070 super, and was also having random crashes. Turns out that my 750 power supply was too old or not powerful enough to power the system. Replacing the PSU fixed it.

Thanks. I'll try the chatgpt thing next time I have the crash.

As for the components, I got the PC in 2020. For some reason I can't find the exact order on their site, but this is the computer: https://www.dell.com/support/manuals/en-us/alienware-aurora-r11-desktop/alienware-aurora-r11-setup-and-specifications/specifications-of-alienware-aurora-r11?guid=guid-7c9f07ce-626e-44ca-be3a-a1fb036413f9&lang=en-us

But it has different options, so that's not entirely helpful. From googling it looks like I need to open up my PC to see what the power supply is, so I'll get around to doing that soon.

The fact that it's pre-built makes me think it is less likely to be power supply, as it should be matched to the components in the package you bought. Did you do anything different since it started doing this?

A picture of the inside of the case would also be helpful to see how your airflow looks and how good your heat sink is.

But yeah seeing what chatGPT says about the crash log would be my next step.

You can see your mobo, ram, and CPU info in the device manager and system info control panel in Windows.

I don't think I've done anything different. I'll open it up when I get the time and take a picture.
