When I try to put my Windows 10 (version 1809) PC to sleep, it will not resume correctly, and seems to wipe the TPM settings, meaning I have to recover using my Bitlocker recovery key. Is there anything I can do to stop this happening?

My system configuration is as follows: AMD Threadripper 1920x, Gigabyte Designaire EX X399 motherboard, 4x8GB ECC PC4-2666 memory, MSI N760 Twin Frozr OC graphics.


This was a really tricky problem to debug. It appeared that the problem lay with my graphics card, which had a legacy Video BIOS that did not support UEFI. I flashed the card with a UEFI version of the BIOS from the MSI forums, and I was then able to put the computer to sleep and resume without difficulty. I still don't know why it interfered with the TPM module, but this does seem to have fixed the problem.
