Sometime this morning the screen on my mac became very distorted (almost pixelated.) I restarted while holding the shift key and it was resolved for about five minutes, then started up again. A friend suggested it could be a blown video card? I've attached a photo.
Starting two days ago, after about 20 minutes of use on my mac, some of the icons on my desktop will suddenly have distorted pixels, as well as all of the open windows will have a black box surrounding it. I am almost positive that this has nothing to do with my video hardware going bad, rather something corrupted in the operating system. This has happened sometime after I had installed the Adobe CS5 photoshop trial. I have recently uninstalled it, but this problem still persists. As soon as I log out, or restart the computer, everything is back to normal. When the 15-20 minute mark comes, all of a sudden everything starts getting distorted. I am also running Mac OS X 10.6.3 currently.
In the image you can see that the bottom dock is corrupted looking as well but the icons stay in tact. This is very odd.
This is the image I get on my iMac 2.4 GHz Intel Core Duo OSX10.5.4. I have repaired permisions and removed all login items. Once I move the cursor or open up a window the screen clears behind the cursor or window etc... It freezes up at least once or twice a day...
I started up again and attached another screen, the image was normal on both screens. But alone the iMac still starts up with the pixelated screen.

I have a G4 Powerbook 1.67 that I don't take anywhere. It just sits on an iCurve as a home computer. Never been dropped, damaged, looks as good as new.
That said, the screen sometimes gives me these red moving pixels which distorts the screen image a bit (pic attached). And lately the screen has been going out at times with lines across the screen, then intermittent blackouts.
I have a macbook Pro 13", bought in 2010. Recently my screen has been going pixelated at random times, it normally goes away fairly quick but is happening more and more. I'm wondering if it is the Video Card which needs to be replaced?
I have been having problems with my Macbook pro(5 months old) screen lately. The screen goes all pixelated and messed up, please see pictures. I don't know what is wrong and surely this can't be lag as my laptop is a pretty good model and from the most recent update.It does this randomly ever now and again but it is very concerning to me. Should i consider asking for a new mac/refund.....
I've had two crashes (really weird ones) since I got my mac pro 3 weeks ago. Is that too many to have and should I be worried about this? Description: The screen distorts - I see a version of the app I had open but it's all distorted and pixelated. There are medium to small squares everywhere that imbue things w/ different colors. I can move a version of the pointer around (almost like a pointer attached to a box) but I can't click on anything. Nothing responds.
I was using my computer and it was just fine. I closed it carefully (as always) and left for a few minutes. When I came back and opened it up, the screen was completely pixelated. I turned it on and off and read several forums and tried cleaning the drives and nothing is working at all. As I've been working on it parts of the pixelation of bright colors have begun flashing a little bit. Not a lot but a little. Black doesn't seem affected by the pixelation but you can see lines in the white areas. Also when images are fading in and out, they don't become pixelated until they are at their brightest. When they are fading in and out they appear fine.The graphics card in my computer is a Nividia GeForce GT 330M. SO I'm guessing from this that the graphics card is damaged or whatever. I can't afford to have apple repair it for $400 and the nearest apple store to me is two hours away.

After the 10.5.1 software I'm having a problem with distorted (stripes etc.) icons and menu dropdowns. Apparently not on my desktop or programs like Safari, Mail etc., only on icons and menu dropdowns, which I find odd. Sometimes it's gone, but after some time it reappears again. Anyway, sometimes my Mac (iMac G5, PowerMac12,1, 1.9 GHz) is going bonkers completely, which results in a first pink, then black screen. A hard shut down is then the only option. However, I guess it's videocard related (ATI Radeon X600 Pro). I did all the tests, fixes you can think of, but without any results. I contacted Apple support, but because this is an iMac, you can't just replace the card, they told me that the whole motherboard should be replaced, which will cost me approx. 700 EURO. Of course I am not willing to do that, which means that I'll have to buy a new Mac. Of course a new Mac is always a delight, but I find replacement after just 2 years unacceptable.

I was using safari and my screen locked up. Large areas got distorted and little (maybe 1/8" blocks) started flickering all over the screen. It wouldn't recognize any input from my keyboard or mouse. This really scares me for a number of reasons: I wasn't doing anything very difficult to cause the crash, The computer has basically nothing on it, and the reason I bought a mac was for its stability. I head back to school tomorrow (read: I head far away from a mac store), and I need to know if I should go by the mac store before I leave. It's a 27" i5 if that makes any difference.
I own an early 2008 iMac running Snow Leopard. A few months ago, it started getting a little buggy and running slow, you know, things you would expect from a computer that's now 2 years old. But then it started freezing and giving me "kernel panics". Of course, the first thing I did was install VirusBarrier and remove any and all viruses it could find, and I repaired the disk and disk permissions and ran all the diagnostic tests from the install DVD. Then I left it unplugged for a day, upgraded the memory from 2 GB to 4 GB and did everything a second time. After all that, everything seemed to work just fine.
Now it seems to be starting all over again! This time the virus scan only picked up a few Windows viruses on an old external hard drive and repairing the disk, disk permissions, and running diagnostics turned up nothing. I've done everything I know to do, short of taking the thing back to Apple! Right now, the main issue is this bug at startup that's really just freaking me out. Linked is a video of what happens. The apps that run at startup are BumpTop, HughesNet Status Meter (as of last month), and Brother Printer Utility. [URL]
I'm on Mac Pro os x 10.5.4 and having a problem with my computer waking up from sleep or as it is booting up.
As it wakes up from sleep, the screen becomes blank or shows weird, pixelated bars all over the screen. When I try to move the mouse or press something on keypad, the computer freezes after and I would have to force shutting it down by pressing the power. It doesn't always happen, but quite often these days.
Also, when it's booting up, it sometimes will freeze with a blank screen in the middle and won't show the desktop.
Everything worked fine until a few days ago, and i'm wondering what's suddenly causing this problem.
Whenever I play HD movies on my iMac in full screen with QuickTime, you can always see the pixels, some are big some small, like boxes. Is there any fix to this? also this is a Aluminum mid level 20 inch iMac
I have an iMac G4 running 10.4.11. (not intel). When I turned it on today, it was all pixilated, little white squares in between the colored ones. I can hardly make out what is on the screen so I can?t really choose anything using the mouse. Everything else seems normal except for the the screen.
Got the iMac 27" Late 2009 (bought it when it came out). Its always had the 'pixelated' issue (see attachment) just before the login screen appears but I've never bothered too much as its not been a problem, until recently where I am getting a lot of 'Kernel Panics' (screen wipes down and locks done entirely, have to restart to get the system up and running again). I am starting to think that the screen issue is finally starting to shows its true colours. Yes, I've done the PRAM resets, disk repairs, up-to-date with all the software etc. No joy.
I have a late 2006 24" IMac which has a myriad of issues. The most concerning to me at this point is the occasional appearance of a 1-2 pixel wide horizontal line which runs from 2" across to sometimes as much as 12" across the screen. It happens most often on the desktop and in firefox. It disappears as mysteriously as it appears.
Could the graphics card be going bad? Any ideas on what might be happening and how I might be able to solve this.
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.

I'm having a problem on my mbp screen, although it happened only once just an hour ago. The screen goes flickering magenta and white and some pixelated image. I needed to force shutdown using the power button because it seems to stalled. After restarting, it went to normal. I dunno if it has anything to do with the gfxstatus utility that I've installed the night before. I know it might be the nvidia graphic card itself but I just don't have a clue right now. My MBP is just 8 days old and my 1 to 1 exchange has expired since it covers the 1st 7 days only.
My MBP spec: MacBook Pro 17" AG, i5 2.53 Ghz, 4gb RAM, 500gb Hitachi HD, 512mb nVidia GT330M video card, Mac OSX 10.6.3, with everything updated. Tthe attached pic is not showing the exact image since the screen was flickering etc and I'm just using a camera photo. I just noticed while I'm just surfing this forum + facebook, my temperature is at 67-70 degree celcius, which is high (normal around 38-45). I look at Activity Monitor and found that Kernel Task is using up to 80% of CPU. I have a feeling that this is not normal, and it had not happened before.
New to using Mac's... this is an older desktop but I haven't had any issues with it yet. I went on to use it and the colour was a yellow/orange looking colour and it changes the way pictures and text look on the computer. Is there a way I can troubleshoot this problem or is it something to do with the monitor itself?
Lately my Macbook's sound has become distorted while playing videos or watching flash videos/streams. This doesn't happen all the time, it seems to happen most when my computer is overloaded (which happens a lot due to the Safari Flash plug in). The distorted sound is not just in the video, but the entire computer is effected (any sound including iTunes music/volume control sounds/etc). I found a way to fix it, which is to plug in a pair of headphones into the audio out port (which then plays sound normally through the headphones) and then when i unplug it the sound is all fixed when playing from the speakers.
I want to prevent this from happening again though because it's annoying enough when Flash video starts chugging in Safari. Whenever it f*cks up the sound I get even more pissed that I have to go grab a pair of headphones to fix the problem. This happened like 5 times today. I have SL, if that matters since I never had this issue when Leopard was installed.
I noticed that when I browse in Safari, I get a distorted menu bar after a while. It generally pulls in content from the page that I'm browsing. When I use Chrome or Firefox, I don't have this problem at all. I'm running a 1.6 Ghz MBA Rev. A. I have had issues with graphics lines in the past too.
