This happens every time when I turn on my computer or restart. Otherwise all other computing and display are fine once I get passed the log in screen.

I recently got my laptop back after the logic board was replaced and now black lines with white text keep appearing on the screen. When this happens I cannot do anything except hold the power button in to reset.

There's some known documented issues concerning the Nvidia graphics chip in the particular model of macbook pro I have.
Basically when turning on the machine, the screen is filled with black & white horizontal strips like a piano keyboard, but thats it - it doesn't actually boot up fully at all, you cannot hear the hard drive running !
Would the hard drive have anything to do with this ?
I explained this to apple telephone support & they informed of the article

& stated that the symptoms were linked.
On taking the mac to an apple store they ran a special 'firmware' boot up 'test' using an instore ipod to determine if it was a faulty Nvidia chip, so as to prove to Nvidia, the company funding the repairs whether it is that to blame.
Because the machine didn't even boot up & complete the 'test' they couldn't say whether it was the graphics chip - so 'no free repair' under extended warranty & the final answer was as usual ' buy a new logic board' that will cure it !
I have a 2007 MacBookPro. shortly after installing Lion 10.7.3 and VectorWorks 2011 I started getting vertical blue and black lines across my screen on startup. They remain with in the apple while the computer boots and the everything freezes. I tried all of the usual fixes, recovery, safe boot, reset PRAM, battery, etc.When I tried to boot of a system disc I get a message sating that I need to restart my computer. Upon restart same problem occurs. 2 months ago I took the whole thing apart and cleaned out the guts. Reconnecting all cables back together, I came across, what I think is the camera cable. Since my camera has been erratic, i decided to test the problem with it connected and then disconnected. Connected same problem. Once i unplugged the camera everything went back to normal, until now. The same problem returned. I cleaned out the guts again. This time I unplugged the hard drive to try and boot off the C drive, but still get the same problem. This morning It decided to boot up. I was able to copy my essential files onto an external drive.

I've had my iMac for over 2 years now. Last Thursday, I left it on for more than 3 hours and it started having black and white verticals lines appearing on the bottom and top part of my desktop and the cursor. Yesterday, when I checked it again, it was still there! What can I do to fix it, WITHOUT going to a Apple store?

Simply using my Imac for watching tv on the web, Hulu, and left to help my wife get groceries in the house. My wife checked her email and closed Safari.
I came back in roughly 10 minutes from when she shut down Safari to see a black screen with white pinstriping, and the mac being totally unresponsive. Shut down and rebooted, sent off the report to Apple, and am now here with seemingly no problems.Â
Needless to say, as a photographer this computer is just about as important as my camera. Should I be worried? discovered the thread to this issue, which appears to be quite extensive.Â

So for the first time in over a year since I purchased it, my iMac crashed twice.The first time was this morning, i went to do something and the screen went black, and my secondary display got black and white lines. I had to restart. And the boot screen with the apple logo hung around for a while.
Then, later on the screen went whacky after trying to wake it from sleep (not full sleep just display sleep) and had a bunch of moving lines and then I couldn't see anything. So luckily I got a picture. After restart, it seems fine.I'll call apple care in the morning, but thought i'd try my luck here.

When i minimized windows the white thin line appears on the screen. The line disappear right away.
This is a big concern for me because my macbook pro retina 13' is still pretty new.
I got my macbook late Sept 2013.
The screen started by having the occasional 'white out' where it would be in use and a white screen would fade in for a few seconds then usually return to normal.

Since yesterday, my screen has been acting really wierd. Every few hours, the screen goes all fuzzy with a bunch of white lines on it, and it becomes completely unusable. It only happens for a few seconds each time (fortunately, it's fine right now), but it's kinda got me worried because I need to keep this computer for 2 more years before getting a new one, and I can't afford to fix it. I can't stop using it because I need it for school, so if it breaks, I'm completely screwed.

i was working on my macbook pro and suddenly the screen went white with lines through it. i tried a reboot and after the Apple icon shows screen goes white and does nothing.Â
i was on wireless so wen back and connected through wire and left over night in case it was heat
I've had my MBP for about 2 weeks and yesterday a white vertical line about an inch long appeared on the right edge of the screen.
It went away after a restart, so I thought nothing of it, but now another one has appeared. Picture:
They mostly appear only on the desktop, but occasionally crop up when I'm running apps.
Is this something I can fix or is it a video adapter issue? I have searched and come up with some similar motherboard issues but they are mostly older macs.

My MacBookPro 15" 5.3 worked fine until today, All the blacks (rgb 0,0,0) on the screen become red stripes.
When I boot into Linux or Windows the same problem appears, so it's probably a hardware problem.
I have no expensive adaptor to connect to an external lcd screen, so I don't know yet if the problem is in the mac screen or in the cabling or somewhere else...
Here are 2 screenshots of black squares a drawed in Illustrator, one taken on the mac (cmd + shift + 3)
one taken with a camera (where you can see the red lines)

I woke up to my MacBook fan going nuts. Had an error message on the screen that said something about a disk error. The machine wouldn't do anything (force quit, launch app) so I hard powered down. Now.....NOTHING. All I get is the white screen, followed by the flashing folder. Here is what I have tried so far.
I already booted from the restore cd that came with it and opened disk utility. The hard drive shows up as something like disk1 but not "Macintosh HD."Tried to repair permissions and got an error message. Thought then to do an archive and install......and the HDD isn't even a viable option to install the OS on.
I had the original (but smaller) HDD that came with my MacBook, so I put it back in and everything booted up just fine and is back up and running. (Thank God for MobleMe that had all my contacts, etc on it). But I still have some info on that other HDD that I need. I ordered a usb enclosure for the drive to maybe try some recovery, but it seems to me that the HDD failed or something. Is there anything else I can do?
What is going on here? Should I be worried? And I searched. Voiceover is not on.

My mac is fully up to date and I can't seem to work out why this keeps happening?Â
I've included some screen shots so you can all see what I'm talking about. Thoughts?Â

Just received the new 13" macbook air yesterday and today have noticed some very thin horizontal banding lines across the bottom portion of the screen.
Has anyone else noticed this, or check to see if your one has this problem.
It is quite subtle but it makes the icons on the dock look as if they have a card like effect through them.
Easiest to check if you make your screen wallpaper the dark grey colour.
On this the top part of the screen seems consistent, but at the bottom part there is very thin white horizontal lines. I tried updating the software, but it seems to be the same - looks like a faulty display may have to send back,wondering if it could be fixed with a software update.
The strange thing is black and dark colours do not produce the effect it only shows up on greys or medium contrast colours like blue.
My Late '11 15inch Macbook Pro went bonanas today. When it starts up there all these black horizontal lines running across the screen jiggering jabbering everywhere and I see three apple logos (due to GPU glitch I am guessing) after loading everything goes white and my laptop heats up and battery dies within like half an hour. I was bummed but then like after restarting a bunch of times and recharging my laptop it starting up normal again! I was super happy, but then it experienced the same crash next time the battery died. So, this has been going on and off;

A few months ago, I bought a macbook pro and it was doing fine. But recently, every time it starts, a blue screen appears for a split second then it goes to log- in. Then, every time I shutdown, it will also show up for a split second then shutdown. It doesn't affect the computer but I'm just wondering how to stop it.

I still have the appearance of the gray screen after performing all the solutions provided by apple support. What shall I do now?

Today when I turned on my MacBook Pro (Mid 2010 model) , the apple logo appeared as normal, but then the spinning gear and a progress bar appeared under it. Now everytime in turn my computer on, this progress bar will appear, get to about the 2/3 mark and then the computer will abruptly turn off. I have read articles about this saying that I have to format my hard drive. I want to know if there is a way to fix this problem with out having to format my hard drive.
