HP all in one - random black screens for 1 sec

[xxx68]

Hello, I have HP All-in-One PC -27" (i7 8700, GTX 1050, 1TB, Win10) . The problem is that sometimes (not everyoften) there is black screen for one sec. I tried reinstall windows and gpu drivers but no change. How could i fix it ? It does not bother me that much but I would like to sell the pc in near future. Thanks

Look in the Event Viewer and the system subsection, see if anything pops up that might shed some light on the issue

Try tapping the machine and see if it flickers more. If so then there may be a loose connection.
