IMac :: Screen Capture Pixelated Screen At Start Up OSX10.5.4?

Dec 4, 2008

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.

IMac :: Pixelated Screen Display At Startup

Oct 30, 2010

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]

IMac :: Pixelated Screen At Login And Kernel Panics

Oct 14, 2010

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.

OS X :: IMac 24" 2006 - Odd Pixelated Line On Screen?

Jan 14, 2010

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.

PowerPC :: Powerbook G4 Screen Red Pixelated / Screen Going Out?

Jul 8, 2008

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.

OS X V10.7 Lion :: Screen Keeps Flashing As Though A Screen Capture Was Being Made?

Jun 21, 2012

This is unnerving. At random intervals, my screen flashes. It more like "winks" - as though a screen capture was being made. Actually, when you make a real screen capture, the screen doesn't wink, but that's the impression I get. The screen doesn't flicker or flash like it's a hardware bad connection, but goes through a fast, but continuous normal-white-normal cycle. I'm looking at my activity monitor to see if something is unusual, but I can't tell. Everything I look up seems to be real.

Mac Pro :: Distorted Screen - Almost Pixelated

Feb 18, 2010

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.

Mac Pro :: Screen Suddenly Freezing Up And Becoming Pixelated?

Dec 26, 2010

I own a Mac Pro (2x2.8ghz Quad Core Xeon, 6gb DDR2 Ram, Nvidia 8800GT, running in 64-bit mode), and a 30" cinema display. I am running OS 10.6.5 at the moment as well.

What happens (and its been happening all day, rarely happened in the past), is that my entire screen freezes up for no real reason, and becomes completely pixelated and nothing but my cursor moves.

The pixelation even makes it through the force shut down and into the grey apple startup screen, the logo is pixelated there as well.

For some reason, I can't seem to reset the PRAM (no second startup chime?), and I can't seem to enter safe-mode either (shift at startup?)

Right now, the problem isn't happening, but at this rate I expect it to start pixelating very, very soon.

Does anyone have any tips?

I have AppleCare, but I need to fix this asap. I'm a photographer and a very big project depends on it (needs to be submitted by tomorrow morning).

Mac Pro :: Screen Distorts And Pixelated - Nothing Responds

Mar 4, 2008

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.

MacBook Pro :: 17 Inch Screen Is Pixelated?

Jun 19, 2012

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.

Mac Pro :: Pixelated Screen When Wake Up From Sleep Or Booting Up?

Sep 17, 2008

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.

MacBook Pro :: Screen Flickering Magenta / White And Pixelated Image

Jun 12, 2010

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.

IMac :: Cannot Load Start Up Screen?

Jun 13, 2010

Something is wrong with my HDD.

I don't think it's dead but something to do with the indexing of the HDD.

I can go into target firewire mode and i am backing up my data as we speak. However I do not have a big external HDD that i can back up everything so I have to pick and choose.

I have diskwarrior but it does not boot up. It says cannot find boot hdd or something and shows a No entry sign on the grey loading screen with the spinning gear.

I tried disk utility to repair the HDD but it says it tries three times and fails. Cannot locate the index file. I think this is my main problem here.

If i try and boot in verbose mode it shows this [URL] something message and repeats that it cannot locate the file. I dont even know what this is as i've never been to this website.

Anyway I can repair the index file and see if mac os x will boot up? Or you recommend a fresh install?

I just want to boot the mac once so i can look for some files because spotlight wont work since it says its trying to index the macintosh HD from firewire.
