Intel Mac :: Keeps Freezing Up - Pixels Distorted / Horizontal Lines On Screen
Jun 5, 2012
I purchased a late 2006 intel core duo iMac 20'' with an upgrade to os Lion. I've been using it for less than 24 hours, and it has managed to freeze up on me twice, with a followed appearance of pixel abnormalities, horizontal lines, etc. I did my research and it seems to be a graphics card problem, which is a Raedon ati x1600 ,256 mb.
Info:
iMac, Mac OS X (10.7.3), Late '06 iMac/2.16ghzICD/2gb
when I start up in Safe Mode and only in Safe Mode in my iMac (mid 2011- HD 6970M 2048 MB) appears white horizontal lines. I changed already the graphic card almost before a year.
Info: iMac (27-inch Mid 2011), OS X Yosemite (10.10.1)
I've had my macbook air 13" 256GB for four days now, I had it shipped to me in Canada because I wanted the ram to be changed to 8GB. When I'm scrolling around on the internet I see a horizontal line appear in the lower half of my screen, it disappears quickly so I haven't been able to get a screen shot. I have apple care, should I take my laptop in? Is this normal? I've been very careful with my laptop, I haven't dropped it or anything (I even have it in the Tech21 Impact snap case).
I have a MBP purchased in late 2006 so it's fairly old.
Lately I've been having really random lock ups and freezing maybe once every week or so. Sometimes when I hard reset it, there's a few horizontal lines across the screen, usually just on the background. It'll go away if I restart it again.
I used the onboard disk checker and no problems are detected. Is this a sign that the hardware will fail soon?
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.
I use an Intel white iMac 2.0gHz as my primary computer. So far, it has given me no trouble. However, lately I woke the computer to discover a yellow line of dead pixels all the way to the right of the screen. It was discouraging but since the line was out of the way, it wasn't a great deal. However again, later today, I woke the display to find another line running down the middle of the computer. Oh gosh! Anyone know what is going on? Is it the display or the graphics card?
Over the past month I have encountered a number of bugs with Snow Leopard on my MacBook Pro (mid 2006). Ever once in a while, usually during high performance task (like watching flash or encoding with handbrake) the temperature of my cpu will spike to 85-90 degrees celsius and then the system freezes.
During this freeze, I can still move my mouse, but I am unable to click on anything on the dock or any program. Moving the mouse over the dock does not invoke the magnification either. I have to do a hard reset to fix the problem.
Also every once in a while, a long blue horizontal line will appear in on the screen. (sometimes their in iChat windows, sometimes safari, and sometimes the desktop as shown in the photo).
my MacBook pro display that there are frequently horizontal grey lines going across my screen. I've noticed it mostly when the display color should be grey or white, but that's not always the case. It occurs mostly in my Google search bar using Firefox, and also occurs heavily on Facebook in the comments/reply section of a post. Outside of the browser I've also seen it when looking through some personal photos, especially of the sky, the lines will seem to sort of outline different contrasts in white or light tones, kind of like the Magic Wand tool would do in Photoshop. The lines do flicker and change when scrolling.I attempted to snap a photo with my iPhone the best I could.
My specs:
-13" Macbook Pro (2009) -Intel Core 2 Duo 2.26 GHz -NVIDIA GeForce 9400M -Resolution: 1280x800, 32-bit Color
I am having issues when watching video's on my mac, which seemed to happen after upgrading to OS Lion.
When watching video's horizontal lines float up the screen, it tends to happen when the camera changes or something moves. The line almost disjoints the picture slightly as it floats to the top of the screen. This is obviously very distracting!
I have a 2 month old rMBP Mid 2014 and i am experiencing horizontal lines in the middle and bottom of the screen. For example, If i was browsing a site and then close the window you can still see parts of the website in the middle of the screen. I took the laptop in for the technicians to have a look and they a blaming it on the software,claiming that Gfxcardstatus is causing the problem. The problem still persists even with gfxcardstatus turned off. Does Gfxcardstatus do this? Is it the Lcd or gpu failure? Take a look at the photos ....
Recently I have noticed that in certain videos, specifically those that have a lot of movement and blinking lights there is a horizontal line that will appear and float up during playback. I tried using different media players and the floating line remains. I have also tried to de-interlace in VLC to no help. I will also add that all of my drivers and software are up to date.
I wonder if anyone can help me. I am not very technobod and there are progressively awful problems on my Mac until it is now so slow.I need to fix it before it dies altogether, or I throw it out of the window.....Problems:- Thin black lines randomly appearing across the windows. Ghosting of windows, they leave another version when moved. Sometimes windows just white out in areas with scribbly lines like pretend text. Sometimes windows have large bare patches all of a sudden or go see through Programs keep just quitting for no reason. The whole computer just freezes every now and then. Sometimes it waits and returns, occasionally it crashes completely. It is really painfully slow and can take me considerable minutes to open a new window or get something else up on screen. The tool bar sometimes goes all skeletal with no background. Loads more silly things like this... all random.
It is driving me absolutely potty. It's only used by me doing emails, filing pics, designing jam labels, letters, going on forums and things. I don't give it loads to manage unless I'm doing something spectacularly stupid. This computer ought to be big enough to run a design studio..I have tried mackeeper, found it gave more problems than it solved, and uninstalled that, I've tried Clean my mac and only cleaned some, I left the universal binaries and the Caches alone. I then tried Onyx and fixed some listings (I kept the report) and cleaned up the caches in that, then restarted. It is now even slower than before I started fixing it, and all of the problems are still here. I've got time machine for back up. What can be going wrong?
Anyone think this is a good deal? http://www.amazon.com/Apple-MacBook-MB003LL-Laptop-Processor/dp/B0006HU4DK/ref=pd_bbs_sr_1?ie=UTF8&s=electronics&qid=1227225131&sr=8-1. I bought the Rev B, but had to return it because of 5 dead pixels in the center and the horizontal line issue. I am thinking of saving over $1,000 by getting the above. It is new/in box and from amazon. This is the best deal I have seen. It is even cheaper than the refurb models at apple.com.
On my screen when looking at whites or light blues, I seem to notice these faint horizontal lines only on certain places on my screen. For example, on the posting page, the light blue has very lite horizontal white marks on it, only in certain places. (I tried smacking it...(not to hard...I couldn't have damaged it right
i have been Noticing about the Horinzontal linesASA i open my MacbookPro i see No color but when you move your mouse you can see the lines... which cut the mouse partially, Even when you visit forums the line could be see
I noticed that my built in iSight camera displays horizontal lines. Could this be an software issue that will be patched? It occurs in all applications, in all users and after an clean install.
Info: MacBook Pro with Retina display, Mac OS X (10.7.4)
I received my new 15" PB a few days ago and I can notice faint horizontal lines on every other row of pixels. I didn't notice this on the model before this or even the new iBooks, but working with photos, graphics, and video is aggravating with these lines.I called Apple Support and they seem to think this is a limited issue. I'm sending it in to get repaired or to get a new screen put on it...stinks when it's 4 days old and I'm already getting it "repaired"
I have had my iMac for two years now and when I first got it not a week later the video went out, well at that time it was still under warranty so I figured, what the heck I'll go get it fixed. Waited a month got it fixed got it back, works perfectly. It's now 2 years later and everytime I try to run anything intense, i.e. World of Warcraft, or any game for that matter (also happens when the majority of the screen is dark) these horizontal lines appear, the darker the screen is the more intense the lines but once I open a lighter/white document the lines disappear.
If I use the screen saver (flurry) is starts to do it also and you can clearly see RGB pixels all across the screen. I have been searching the internet for a good six months hoping someone will have the same problem, but that does not seem to be the case. If anyone has any idea what is going on, I have tried to reset the SMU and the PRAM but to no avail, I have also heard the swollen capacitors issue and have checked the board for swollen caps but all are flat. As far as specs go it is an iMac G5 2Ghz (Summer 2005).
i got my imac this june, so i'm not sure what generation that makes it. (somone let me know plz) anyway just today i noticed I have some horizontal lines going across it. very faint and hard to notice, but i'm anal and i noticed them. My first instinct was to find out how to degauss this monitor.
I've had my 15 inch Macbook Pro for almost four years and haven't had any major problems with it until today. I was browsing online when suddenly my screen was filled with this pixelated horizontal lines all across the screen.I restarted the computer... heard the start up chime then came a grey screen with the same lines, I can see the apple logo at the start up and the loading bar underneath it... then the screen turns blue, still with the lines and that is all I'm able to see
I have an Apple iMac 20" 2.16 GHz Intel Core 2 Duo. I work on photos in Adobe Photoshop CS4. Am running Snow Leopard 10.6.4. Am getting thin horizontal lines across the surface of the monitor. Reduced the resolution of the monitor from 1680 x 1050 to 1344 x 840. For a while, it was better but the lines are back again. Any idea what is causing this problem? Is it software, a setting on the computer or maybe a problem with the video card? Hope it is not a bad video card.
