After building a new computer (Ryzen 5 - 5500), I fitted 2 hard drives.
1 for Linux Mint 21 & 1 for Windows. 11 Pro.
I spent 7 days testiing out Linux & while doing that ran a 7 day test running Boinc - 7.22.1.
Next I installed Windows & Boinc & still testing Boinc with 2 days remaining of test.
For the 1st time in a very long time, had to abort tasks as they were suspended by prefs.
Checking both Web & local prefs, I cannot find any where to prevent GPU crunching just suspend when computer in use.
I don't do GPU crunching.

Is this a Boinc issue or an issue for the project?
This did not occur when using Linux.

Web preferences.
Go to the project website, your preferences, Project preferences and uncheck use of the GPU(s) there, then save the page and have BOINC contact the project.

Ouch, thanks Jord.
Don't know how I missed that.
It worked, sadly I didn't do the job properly, it downloaded another 4.
My fault, I didn't uncheck Nvidia GPU.
Hopefully on the next download, it will work.
Surprised that in 7 days, no GPU tasks downloaded in Linux.

I suspect, not the right driver.

Use of GPUs is a per project preference, so if you don't want to use the GPU and you have multiple projects, make sure to uncheck using the GPU at all the projects.

Thanks Jord. Noted.
