Problem with horizontal lines across screen on boot
Dell Inspiron i5 laptop
Intel HD Graphics 4000
I am posting here as I'm not techie enough to know if this is definitely a graphics issue.
For a short while now there have been multicoloured lines, though mostly pink, appearing across the top half of the screen when booting up.
They are quite random:
Sometimes there is a narrow band of lines, sometimes a wider band.
Sometimes it's just one quick flash of lines, another time they appear several times, another time not at all.
The lines only stay onscreen for a second or two, and always disappear before the login screen appears.
We have run Dell's SupportAssist to do a thorough check of the laptop, and this is not indicating anything is wrong with the laptop, except the battery.
I'm looking for advice - as simple to follow as possible please - on how to check this out further.
Thanks
