HP Prodesk 440 G4
Microsoft Windows 10 (64-bit)

I am facing problem in my two desktop. Model: HP prodesk 440 G4. One PC's problem is cooling fan is moving in high speed & there is no output in display (display is blank). Also keyboard are not getting any connection. I have tried so many things but the case is not solved yet.

Another PC has an issue with starting. This one is signaling in the startup with red light and beeping.

Please help me with the solution please.
