My display show dot after few second it gt back , but same keep happen & even sometime laptop get hang. I have done following things already, My hard disk was old & making noise so I have changed it to new SSD Install Fresh windows 10 & even try laptop original setting using recovery Install new drivers Changed all Ram But my display problem is still same, I have attached display photo also, but every time display error change. My laptop warranty is expire 1 year ago. so any help would be great.
Your computer needs Windows 10 video card drivers. As well as all Windows 10 drivers for the computer. Dell did not create any Windows 10 drivers for this computer.
I have try window 7 & windows 8 also , dell provide drivers for windows 7 & 8 . I have install all the drivers as listed on dell for my laptop. But my problem is still same.
Attach an external monitor. Does the same fault show on it when it pops up on the internal screen?
If so, you likely have a video chip going bad - it'll soon be time for a replacement mainboard.
If not, the first thing to check/change is the internal wiring harness that runs between the mainboard and the screen. If that doesn't solve the issue, replace the display panel.
