Dear HP community. We use a lot of HP 450 Probook series products, recently the G9 models started showing

"/DMA Protection / The device attempted to access memory that it was denied access to".

Scanned device drivers with HP utility, no updates found. Laptops do not work once every 90 minutes. Tried disabling DMA. Now the laptop has a BSOD and the laptop reboots.

We are desperate. What is the solution to this problem?
