Mac Pro :: Multi Color Single Pixel Lines - System Crashing
Jun 17, 2010
I keep seeing these weird multi-color single pixel lines across my windows and my system is crashing alot (rather it becomes completely frozen and non-responsive). I don't know if this is a video card problem, or memory issue, or just something in the system OS. It does seem that it happens quite often while running Handbrake. I'm still getting these lines with a fresh OS install, so I'm thinking my original video card is on the way out. Will replacing it with actually improve performance?

I thought it might have been a graphics card problem, but these lines move with the apps even in expose mode.
Its driving me nuts. I had this problem before while on 10.4 Tiger and now again on 10.5 Leopard (fresh install on new hard drive).

Whenever I try to start up my mac book pro I get coloured lines going down the screen. It then just shows me a large image of the power button with the message "You need to restart your computer. Hold down the power button for several seconds or press the restart button" I then do this and the same happens again and I go no further.

I have an 09 Mac Pro Nehalem, with nvida gt120 graphics card running 10.6.2 with the latest mac pro 1.4 efi and two 23 inch Apple cinema displays (the older DVI kind)
I go into system preferences>displays>color and try to adjust color on my monitors but selecting different color settings on either monitor only affects ONE monitor, the other monitor is essentially stuck at whatever color setting it is set to.

I have a macbook pro (2.0 CD) running 10.5.3 my problem is that a few times a day, a bar or line appears on my screen with random color pixels. They go away after a few minutes or if they appear on the desktop, a simple killall Finder command clears them away. Sometimes they appear on apps and will minimize/maximize with them. They also appear on the menubar quite frequently. I have restarted many times, but eventually they always come back. This has been happening since at least 10.5.2 has anyone ever experienced this or know what is causing it?

I have a 2007 Mac Pro 1,1 with attached 24" apple display and utilizing 5 GB Ram and maxed out on internal hard drives. It's been a flawless workhorse and I mostly tax it with Photoshop which it does well. Well, yesterday, I was viewing a small video on my Mac when this issue occurred. Suddenly I saw these squiggly looking horizontal lines on my display. Then I saw a spinning beach ball. I had to shut down.
I double checked my display cables in case any were loose - no issues. Restarted without issue. Went back to work on my computer - no issues doing ordinary tasks such as opening windows, moving files and surfing the internet. Went back into Photoshop and resized several dozen images without issue. Then, this happened again... restarted. Zapped PRAM just in case. Fired up Tech Tool Deluxe (older version 3.1.3) and it found NO problems, I passed all tests.
Then... out of nowhere it crashed again, third time... I don't recall what I was doing to be honest. I shut down my Mac last night and this morning have spent an hour on and so far, so good. However, I'm not taxing it by doing anything intense. I need to use Photoshop for a project I'm working on so I will do that soon and see if this issue repeats.
I've tried searching the forums but can't find anything conclusive to my specific issue. What else should I do? What else should I check? Is this hardware or a software issue? I have temperature monitor installed - should I be looking at specific temperature increases and if so, where?
GPU going bad on logic board? This is a really close up image taken with my iphone, obviously the lines aren't this large.

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?

I have several folders that have albums in them. When I click on a specific folder/album, "mushrooms", I receive the spinning rainbow wheel and then Iphoto crashes. This only occurs with this folder/album. All the other folders/albums work fine.

before switching to Mac, I used an "X-Rite Eye One Display 2" color meter device with software. You can find them most places like Amazon for about $150. The device should still work, but I can't find any software for it for the Mac. After going to the X-Rite web site, I could find no software at all for the Mac as it is only windows based.
Surely someone out there has used a color meter such as this one as they are quite popular especially for graphics artists that use professional graphic monitors. I am hoping someone can tell me how to use my color meter (USB), what software for Mac Leopard I need and how to save the color profile in the Mac OS.

If I have an event, starting on Friday, going on Saturday and and finishing Sunday, is it not possible to get this to show in the month view? I know it shows up in the weekly view, but it would be more helpful for me to have it up show up like this so I can get an overview of the month's forthcoming events. Or if it, are there any mods/addons etc that can enable this?

I'm thinking of making the jump and making my first Apple computer purchase. Time machine will be a welcome native backup solution, especially since I can do it over the network automatically. However, I've read that Time Machine naturally requires HFS+ formatted disks. But I will still have my Win7 laptop for gaming purposes, and of course that requires NTFS or FAT32 for writability. My question: Can I just take a TM compatible external drive, split it into two partitions, and then specify that each computer backup onto its own partition with its own file system?

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

My computer (24" 3.06Ghz intel core 2 duo) won't start. When I try to turn on or restart my iMac I get vertical rows of pixelated lines across my monitor on the white startup background with the apple logo and it will either freeze up or the background turns gray and I get a message that says I should restart my computer. This has also happened when restarting using the Apple hardware test (which doesn't report any errors).

I was browsing the internet on my '08 iMac when the system suddenly froze immediately followed by the screen turning to nothing but vertical lines. I fear this may be an issue with the graphics card, but would anyone be able to offer any further insight?

I want to print out a single letter on one page for a banner I am making for my daughters school leavers party. However, if you make the font size too big it slips onto a second page and it will only fill half a page at its largest. For example, I want the letter 'S' to fill a whole A4 page then the letter 'T' then 'B' etc. I will then print then out and stick them on the banner.

First post here but a long-time reader. Just noticed something that reminds me of win XP like 7 years ago. Images in Preview and Safari have a completely different colorcast than in Photoshop. AKA system is showing colors way off. Any ideas ? This bug has been verified so far in two different systems with CS3 and CS4 and it is very real. I'm using calibrated monitor with a profile of 2.2 gamma.

I am having very frequent system freezes (multiple per day) then when restart the restart is very slow. Activity Monitor shows TechToolsupportDaemon taking up 99-120% of CPU for extended periods. I have a MacBook Pro 15-iInch, Early 2011, with 2.3 GHz Intel Core i7; 8 GB 1333MHz DDR3; Intel HD Graphics 3000 512 MB; running OS X 10.9.3 (13D65).
I am also having episodes for sudden abnormal graphics with jagged lines, Screen split vertically with multiple horizontal lines. Screen becomes totally unreadable. Then sudden total screen freeze.
I made rescue system drives on flash drive when I first shifted to Maverick, so I could use Disk Utility to Verify and/or repair the main disk. When I upgraded to the next edition of Maverick, my flash drives no longer worked. I tried to upgrade the flash drives to the new system, but there was not enough room. I tried erasing the drives but now I have a flash drive with only a small amount of space, the rest is hidden and locked.
What do I need to do to correct the problem of frequent freezes, and then How can I free space on my flash drives?

I bought Brand New Macbook pro 15" Late 2011 Ci7, this is incredible machine. But a month past and i started to notice a very strange behavior: When i using mac for resource "Eating" application or processes my computer starts to Heat-this is normal.
When i close all the apps here starts interesting) I have Istat installed, so i can see what temps are in my system. Computer is cooling, and when cpu reaches 50-55 degrees (Celsium, from 80 degrees, because of heavy load) ,my left speaker produces a single loud pop sound. (like something turning of may be)

a few days ago i unplugged a USB cable from the back of my MacPro 1,1 and the screen turned all blue (like an overlay) and the machine crashed. Since then the computer has been running extremely slow? it takes 15-20 minutes to start up (if not more) and once booted, every action is delayed as the computer is "thinking". I can type about three letters into a search box per minute as an example.The machine has moments of clarity where I can open a window or start launching a program, then to begins to pause again.The machine as of now is unusable. I have been able to get the process manager open and did not see anything unusual.

Ok, I've noticed this week that my 2010 13" MBP hangs a lot when it plays any videos I've bought off of itunes (it's fine with other videos). I mean anytime a itunes video pops up on my itunes player, the whole computer hangs (beachball of death and can't do anything). And it hangs for quite a bit (haven't timed it but a minute maybe?)
At first I thought it was the graphics card as the first time I realized what was causing my computer to randomly freeze up (it's been starting to do that this week but at first wasn't sure what cause itunes was in the background) it gave the wierd color bars on the video screen for the video it was playing (I have itunes play the video in the small box on the left bottom corner). Like the whole video screen was random fubar color bars and not the video (it took a minute and then eventually played fine after me reclicking the video). It has not done that since.
I played around with it and noticed it seems fine when I play videos I have not bought off of itunes but it reliabley hangs the whole computer when I try to play a video bought off of itunes. It eventually plays but it is really annoying particularly cause it holds up my whole computer until it resolves whatever issue it is.
So, hardware or software and any suggestions if it is software on how to fix it?

Installed 10.6.5 a few days after it came out. I have an IMAC white version 4 years old. It now crashes several times a day. Symptoms are screen is locked and mouse and keyboard have no effect. Dont have any obscure software. In fact the problem has occurred when all I have open are a couple of Safari windows. It requires a restart which is pretty annoying as it tends to happen in the middle of doing something important like online bookings.
Earlier versions of this OS had many similar USB problems that were fixed in 10.6.4 (tho Apple never
mentioned them). Seems like the same problems have crept back in.

I�m a newbie here but been using Mac os x for about 10 years. My iBook 12" G4 1.33 has been crashing alot with the black screen saying "you need to restart your computer".or, more often "Welcome to Open Firmware, the system time and date is:.... When i type "mac-boot" it flashes once and goes to an all blue screen with a folder in the center with a question mark on it. One more detail: on the very top of the firmware screen it says: Illegal instruction at %SRR0: ff85e778 %SRR1: 0008 1000
This has been happening for over a year now and we usually get it to start by pressing random keys and even shaking the laptop!! We have learnt there is a real issue with the airport card in these ibook g4�s but mine is the type you can�t get to the airport card without taking the whole thing apart. So its still in there but we dont use it because it brings on these kernel panics, But they continue and are getting worse, I have reset the PRam 100�s of times thru the Open Firmware but nothing changes, Don�t know how to boot through the cd drive as there�s no prompts, everything is backed up, so not too scared but just want my lovely Mac back. I have the discs if anyone can tell me how to use them in this situation, or help in anyway I would be soooo grateful. The forums seem to have a fairbit about thi kind of thing but none of the responses work for us
