Regular crashes. Suspect graphics card.

First and foremost I would advise you to check Dell's forums to see if there are lots of similar issues being reported currently.
Then check which version of Nvidia drivers you are using and whether DCH or Standard (also Game Ready or Studio), your monitor stats (resolution, bit depth, HDR, G-Sync support etc.) and check Nvidia's driver forums to see if any current issues match yours.
The reasons for the above are that you have a Dell PC and an RTX2080Ti, at the moment Nvidia are having a lot of issues trying to get their drivers playing nicely since adding the 30 series into the mix. Problems reported range from simple game CTD to browser corruption (visually), poor HDR performance, black or flickering screens, YouTube and Netflix video performance problems, the list goes on.
If none of the above support/ forum sites give you an inkling as to where to look, come back to us with some more detail such as, when the issues started, any particular apps you are using, how up to date Windows is and any other details you may think relevant.

Hi, thanks for reply, I should have said the issues are with my 2nd PC listed, not the Dell.

Driver is DHC and latest Studio Driver. Issues began when I installed the RTX 3090 as I had been using the 2080ti before in this build and it was pretty solid. Since installing the 3090 I've had 1 BSOD and several crash/shutdowns.

Onboard video chip also? Try disabling card and running with onboard chip only. Still happening?

File Explorer issue... half the forums on the internet would cease to exist without users' similar problems. Could be purely co-incidental. Try a 3rd party file manager - xploer2 lite (freeware), Directory Opus, et al.

It is possible that your power supply can't provide the 3090 with a clean enough or high enough flow when it is under load. The 30 series cards suffer from enormous spikes in power usage when the clock ramps up, it is not sustained, but is enough to strain the power supply if it is under spec. The 3090 is particularly power hungry when hit with a load.
Check your event viewer to see if there are any power related errors noted.
Maybe install HWInfo 64 and/ or MSI Afterburner and use the logging features to keep an eye on temps and power usage (HWInfo in particular for CPU, chipset, memory, GPU power and temps). Either of these apps (other similar ones are available) could point to where your issue originates.

I don't think AMD have on-board chips and I wouldn't be able to recreate the heavy loads that appear to cause the issue with just an on-board chip, anyway. Win10 file explorer does seem very buggy compared to Win7 which I can't recall having such issues with, but who knows really.

If it were me... 1st thing I would do is try the Standard / Game Ready driver instead of the DCH / Studio driver. If problem still exists, then try Standard / Studio driver.




DDU Instructions - Nvidia
1. Get this program, here: Display Driver Uninstaller (DDU) | Wagnardsoft ...get the latest version, and save it to your desktop.
2. Get your vid card driver here, use the Manual Search: Advanced Driver Search | NVIDIA ...save this to your desktop.
Unhook the internet completely.
3. Reboot into Safe Mode and run DDU (Display Driver Uninstaller) choose the "Highly Recommend Option", and just do what it tells you.
4. After it's done, reboot to normal mode, then just double click the Nvidia driver to install. If it want's to reboot, let it.
Rehook the internet.

Several critical errors are shown that match the crashes. The source is tagged kernal-power. One other crash was due to a "bugcheck" whatever that is. My PSU is new and well over the recommend power for the 3090. I've read that power spikes are not supposed to trip the PSU if they are new and from a reputable maker, which I believe Seasonic to be, but it could be. No point in buy a new one until the source is found, though.

I had a thought it may me memory related. I generate over 100,000 4K tif images at a time, using AI software and then compress those images into a 4K file, 4 or 5 times a week. That's a massive amount of data, over 2TB for each project, going through my system. Is it possible the memory can't cope with that amount of images being written to a folder and just slows and slows down until if fails, because other programs need to use the memory?

It says on the nvidia website that standard and DCH cannot be used on top of the other and my Nvidia panel shows I have a DCH driver.

Yes. That's why you would need to use DDU to uninstall the one you have.
You don't have to try other driver(s). It's just a way to eliminate the driver as a cause of the problem.

You need to narrow down the cause, changing driver types could help as Ghot says, so worth a try, the Studio driver may be causing a memory leak (unknown by Nvidia yet) or may be incompatible with an app or driver on your system.
Memory could be a factor (not faulty as such), a large amount of data could possibly introduce errors causing memory to be over written that is in use by a critical service, (I take it you are not using EEC registered memory?), causing a BSOD, so worth investigating.
The fact you have several critical errors tagging kernel power seems suspect though.
The power supply could well be part of the issue, it may well be rated high enough for the graphics card, even under load, but the card can spike to over a 100 watts above spec, which with the system as a whole already hitting the power supply pretty hard, could result in the card not getting the power it needs under those circumstances and thus triggering a kernel power error.
Those utilities I mentioned are free to use and have no pay wall locked features, they would both show you how your system responds when under high load, down to the millisecond.
To rule out a purely graphics card related issue you could download Unigene Superposition (a free benchmark tool) and run the custom tests where you can check the cards performance under differing loads. It is especially useful as it allows you to use as much VRAM as your card has, sometimes a card can have faulty VRAM but it only shows up when in use (the fault could be in the 7 - 8Gb range, or higher for a 3090, for example) and most benchmarking utilities only use the first 4Gb of VRAM.

The noticeable system slowdown leading up to the issue seems to suggest heat, memory leak or just more data than your system can comfortably handle. But since you said the 2080 in the same system seemed ok it is worth pursuing a line of investigation into the 3090 still, these tests are free to perform (other than time needed) so worth doing.
