Strange blue lines on my MacBook
My MacBook Pro was having problems. Apple reseller diagnosed a broken logic board €1000. I went to an other store and they replaced the video card.
The mac is working but now I'm having this strange issue (this problem started before the mac was fixed)
I'm having blue lines (see pictures)
in different websites (not always, sometimes I can work for hours without any problem) the only thing I can do when this happens is power off the mac with the power button.
Is this a software problem or is there still a hardware problem.
On the invoice is noted VGA repair. So not sure it was the graphics card that is changed
