When i boot my laptop, the image on screen appears with problems, can't read the letters and some traces in vertical. When windows start, shows a blue screen with a memory error but i can read it because it disapears very fast.
I thing (im not sure) that can be some problem with graphic card. I have removed the ram cards and swithed, but the problems stays.
Yes, BSOD is the product of software or serious hardware problem.
Since you have some vertical lines on the screen, the graphic chip might be affected.
Seems only service technicians would be able to help you… by the way: what notebook do you have?
