i no expert or technician , don't want make things worse; so, can please help?

kind regards,

                     david.

when not boot everytime, saying not power on? or power on, windows 10 not load or fails boot desktop?

if windows 10 fails load or boot desktop, see a: black screen or error message? if see error message, say?

have tried swapping out video cards see if problem persists?
possible 1 of video cards failing or not fitted securely in system unit along other components such ram sticks.

if not comfortable working in side computer, should take professional pc services company can make proper diagnosis , inform @ same time.
