I own an HP Z2 G5 TWR XW1250 16GB/1TB PC (2X3N4UT).

I installed an NVIDIA GeForce 1050Ti graphics card. It is working ok, but I get a 901 PCIe Blower not detected post error. If I hit a key, as instructed, the machine boots up and runs fine. How do I clear this error?  I know that the fan on the Graphics card is running fine, as is the CPU fan. Is this an incompatibility issue with the graphics card? I updated the graphics card driver, but it hasn't made any difference. The computer has had all the patches installed so it is also up to date. Any help
