hi, i own a hp z800, and i work with music.
I often have frequent disconnections of the sound card, having problems with crackle and popping.
the problem showing the windows event viewer is "The EHCI host controller reported a Host System Error." , and people have told me it may be due to the power supply.
The fact is that they shouldn't be a problem, being the 1250W power supply, and having 6 hard drives and a 1080 you just get powered.
While for USB, I have 3 controllers, with attached: a midi controller (not powered), a midi powered controller, two powered instruments, the sound card powered too and keyboard and mouse, so almost everything has an external power supply, and even trying to disconnect everything the problem comes back.
What can it be caused by? I am going crazy.
