I have a very expensive rig and it started crashing while gaming and also when closing a game.

Day to day operation, no blue screen. Gaming blue screen. Actually cascading blue screens. Sometimes takes as many as 4 bluescreen restarts to get back up.

I've done a clean windows install. It is actually worse now.

I've run memtest86. All good.
Furmark 2 to stress the GPU. Fine.
Cooling appears to be fine. No temp over 70 when gaming.
CPU stress tests, all clear. top of the line.
Tried multiple graphics drivers. Same result.
Device manager - nothing wrong in the manager.
I've run the corsair diagnostic results all green.
Even though I have never had dism online health command fix anything. I tried that. Sfc scannow shows no errors.

I assume it is hardware and not software but from the tests, everything works except when gaming.

If it was power, I would think the CPU & GPU tests would have caused it to bluescreen and with Rogue Trader, I can turn the game on and then exit the game. Crash. Yes, I checked integrity of the game and done multiple reintstalls. Yes Owlcat is a buggy developer but the crashing occurs on other games too.

Any ideas on how to figure out which component has gone haywire? I'm probably going to do another complete wipe and start from scratch but I am not optimistic. I think one of the components is the issue but it only glitches out when gaming.

Hate to break it to you, but sounds like a bad GPU.

Any weird "artifacts" on the screen?

No artifacting. Games look great.

How would a broken GPU pass the Furmark testing? I know some folks think it is unreliable but running that for a long time with no issues and starting a game to instant crashing, seem like the Furtest would crash too.

And I am not saying it isn't the graphics card. Clearly something is broken and causing issues but I would think Furmark would cause it to crash too. And I have zero graphical issues with any other programs. No other program opening or closing has caused a crash. Just gaming. Video streaming looks great.

ANY hardware could be suspect. Power converters found in MB and GPU fail more than anything, then RAM from my experience. Get some IPA and clean all contacts with lint free cloth and blow with dry air. There are some blue screen memory dump and error tools out there. You can add debugging to catch more next time.
Ask copilot how to do all this. You should be able to narrow down to a driver after a couple crashes.

If you have slotted RAM, you can remove all but one stick. If you have iGPU, you can stress that instead maybe.

I haven’t used a consumer grade desktop PC in 20 years but I imagine they’re infinitely harder to troubleshoot than anything else. Maybe your bios has settings that can be optimized for stability.

Try reseating the GPU.

Think heat. My liquid cooling setup kicks into high gear when playing Rogue Trader the fact that you can’t successfully reboot for a time seems to play into this theory too.

100% not heat. The temps aren't getting over 70. Furmark2 at 100% load didn't get over 70.

Have you checked Event Viewer to see if anything is leaving an event in the logs at the same time that it crashes?

Yes but as you know it is easier to read hieroglyphics than Windows event logs. I have cut and pasted the critical errors into Google and haven't been able to gleam much. Before my clean install, everything pointed to windows game bar being the first critical error that then spawned more. Since the reinstall that gamebar error is gone and off the top of my head I don't remember the first error now. I see people online suggesting Windbg to analyze dump files. I may look into that a bit before proceeding. Even though the memtest86 found no errors, I might pull 1 stick of ram and then try things and if it crashes, try the other stick.

I was dead wrong. I ran Furmark again and this time it throttled and blue screened. When I opened the ICU software it was in shutdown mode and then blue screened. I must have hit the benchmark and not the stress test and it was able to survive the benchmark but then if i had let it go longer it would have blue screened.

Mystery solved.

I need to figure out if the cooler is plain dead or maybe the thermal paste has completely dried out. I've never liked the temp with this cooler so I think I will go with a new better cooler.

Thanks everyone.

Boom! Glad you got it sorted. My Corsair H100i has been running strong for almost a decade. It's so damned efficient the fans barely spin at all unless I'm playing a handful of titles.

For the debug errors, just search microsoft.com (it used to be TechNet) and you should get pretty good answers. If you use aggregating search engines like GoogleEvil, your search is just going to get flooded with copies of substandard information for page after page. Not that it would have helped in this particular case, but for future reference. I remember the days of scribbling down the long error codes from one PC to search Technet with another. It was before phone cameras.

Self inflicted wound too. 3 fans mounted on the front. I haven't checked the dust screen in evidently never. I don't think ANY air was getting through. I am going to order some thermal paste and reapply because I bet the paste in obliterated.

Damn, my filter is undermounted and never gets that bad.

Thermal paste should take more heat than any living gpu or cpu but maybe do that anyway just because something isn’t adding up.
I had a dual CPU dual GPU workstation I just sold a couple weeks ago. If it got too many automated requests too quickly it would have everything heat to 90C, throttle to 80, creep back to 90 and do that until it finally caught back up and got a little break. Super common and nothing to worry about. Some requests would time out but it never crashed. “Gaming” stuff is just a whole other thing I guess.

Thermal past can dry out. I've had one older computer that was hitting abnormal temperatures. You also have to take into account on a prebuilt system, it is possible the original paste wasn't even put on correctly. You also never know how cheap the thermal paste is on a prebuilt. The paste was brittle and cracked. New application and 4 years later it is fine. This is said replaced paste machine and temps are great.

Getcha some Noctua NT-H1 (or 2). It's what I use and it's good. Nice balance between performance and price.

Also, ditch the water cooling. I used a Corsair H115i for several years. While good, they do fail. I just went with a big air cooler and now don't have to worry about any leaks or failures.

Looks like paste won't even be needed. Looking at my case the front 3 fans were pulling air in and the radiator and back fan were pushing exhaust out. So with the front fans completely blocked, the thing was a hotbox.

Now that I have cleared the case and fans with my hurricane winds blower, all temps are cooler and I've had Rogue Trader playing for 90 minutes and all temps look good. And that is the longest I have been able to play since the crashing started.

Lesson learned. Check you dust filters.
