What about this looks wrong?

[Darkvillan]

Been experiencing a lot of PC system crashes while gaming, there is no sign showing why this would occur. The crashes do not come with any lag, or anything noticeable. Just one second playing, next im not. Trying to diagnose the problem. Any help would be appreciated. Here is a link to a screenshot of what I am seeing when looking at the resources. Also sometimes the Disk will hit 99%. Please help! Thank you!

Your cpu temps are getting pretty high that may be the problem. The gpu temps also seem to be high. How recently have you cleaned out your fans and case? How new is the PC? Do you have any overclocks?

If you haven't done so you should run a FULL PASS of your memory with Memtest86.
www.memtest86.com

Should take roughly one hour for 16GB.

If that's not it my next guess would be your system drive has issues. Run diagnostics (see drive manufacturer)

If the hardware is fine, and you have W10 you can try doing an in-place upgrade:
1) download MS media creation tool (google) to an 8GB USB stick or dual-layer DVD
2) run "setup.exe" on that while at the desktop
3) choose to keep data and programs (I believe it defaulted to that for me)
4) don't enter a key if prompted

It will then basically replace a lot of the core files in Windows 10. It should then do some Microsoft Updates after. If you still have crashes we can reevaluate then.

You're hitting +80C temps at ~68% CPU load. I'm surprised you're not seeing some CPU throttling. With that heat in the case it could also affect the PSU. I'd redo all thermal paste including the north bridge if possible, clean fans and case inlets and outlets and check the air flow. You might benefit from more fans to move the air.

Just for a test pull the side panel off of the case and check your temperatures. If they go down, you're not getting sufficient air flow.

The model is an Alienware X51 R2, roughly three years old.

GPU hit 90c last night also, and fans were speeding and slowing often

I've moved my desk location closer to a window, and will be trying to run it without the side of the case on tonight, hopefully this fixes the problem, if not I will run through the rest of the troubleshooting steps I have been given here, thank you everyone!

Back to it, after my pc running, maybe 5 hours? It crashed once again, this time after it posted and began to boot, the fans were going abnormally fast and nothing came up on screen. Ideas?

Have you checked for dust inside your pc?

Ended up cleaning inside PC and it lasted a few more weeks, ultimately dying last week lol. But cleaning dust and giving it more airflow helped make it last that much longer
