Common faulty desktop, loud click as either a fan startup or relay engages. Also the botton USB-C port is dead or not hooked up. It takes a good amount of time to update patches and from a cold start over 30 seconds to boot up. I loved my last two Pavilion machines. I thought this would be an upgrade at a good price. Google noise from HP OmniDesk, I returned the first machine they sent me, the second replacement has the same issue... very common.
Very good computer. My only issue is that the network adapter periodically cuts my internet while I'm using it. This is annoying when I'm on a zoom call.
