my pc randomly shows vertical lines(any colour) its so annoying it usually happens when i play games.It may happen like every 1 hour or day and sometimes it stops for months.I ve tryed clean install drivers taking out my gpu cleaning it and puting back,changing my monitor.I also got back my gpu where i baught it,they tested it and they said it has no problems.This doesnt happen if i play with my cpu's built in gpu
