When caliber6.29 version is converted, the CPU usage is too high, resulting in freque

win11 22H2，This will also happen if the number of concurrent tasks is set to a small amount. The proportion is too high in an instant, and then a blue screen of death occurs. Please check this

BUG. Thank you very much.

There is no kernel mode code in calibre so it cannot cause blue screens even if it wantend to. You likely have a hardware issue.

Go to Preferences > Miscellaneous and change the number of Max. simultaneous conversion/news to download/plugin jobs. Set it to a lower number. This will use less cores of your processor and maybe prevent 100% CPU usage. Go all the way down to 2 if need be.

FANS and or LINT is a common BSOD cause under load.

Bulging (failing) Capacitors, is another. (the tops with a X, should not be domed or split )

After testing for a few days, I changed the memory module, but the problem still exists. As long as the number of tasks exceeds 2, a blue screen of death will appear.

Reducing it to 2 can indeed reduce the blue screen frequency, but in this case, the efficiency will be very slow.
