Intel Mac :: Freezes Randomly With Vertical Stripes?

Apr 23, 2012

I'm having huge issues with my 20-inch early 2008 iMac running 10.7.3. I upgraded my RAM (to 4Gb) 8 months ago and everything was running nice and easy until I upgraded to Lion. Either one of these things happen: My screen goes entirely grey or blue with white faded thin vertical stripes at random timesMac freezes working with any Adobe applications (mouse cursor still works but I can't click anything until I turn off and on)Mac freezes for a while and after a 30-second delay clicking and pressing buttons frantically everything goes back to normal 

The strangest thing is that when I play Sims 3 for example (a beast of RAM and video drainer) nothing happens. I tried almost everything from repairing permissions to re-install my memory modules. I couldn't run the hardware test. 

Note: I live in Brazil so sending my machine to a Genius Bar is completely off the question.

MacBook Pro :: Green And Purple Vertical Stripes And Not Rebooting?

Sep 1, 2009

while surfing the internet (I was reading an article on CNN and scrolling down to continue reading), the screen color changed to tinges of green and purple. The entire thing keys, no mouse, not even force quit...nothing. I had no choice but to do a hard shut down by holding down the power button until the laptop just shut off (Macbook Pro). In the middle of rebooting, (at the grey screen with the apple logo on it, I got the familiar circular dial that ticks around as it loads) a screen wipe similar to the effect of some screen savers went from the top of the screen to the bottom turning the screen from grey into green and purple vertical stripes.

It also said "you need to restart your computer" and proceeded to tell me how to do so in four different languages. Upon doing so, the same thing happened...several times. I tried booting it into safe mode by holding down the shift key until the grey apple background appeared and it seemed to be working as the loading was taking forever. Alas, the same thing happened. I took the battery out and held down the power button for 10 seconds, put the battery back in only to suffer the same effect. The next genius bar reservation isn't until Friday.

MacBook Pro :: Vertical Stripes At Boot Then Black Screen?

Feb 23, 2010

I have a MacBook Pro with Leopard. On boot, I get a screen of vertical blue stripes with the Apple logo, sometimes intact, sometimes split across the stripes. The spinning activity wheel is there too. After about 30 seconds, it gives up the ghost and the screen goes blank. It's still powered on, but just the screen is blank.

I've attached an image of what the screen looks like.

I've tried Command Option PR to reset the PRAM and VRAM but the problem remains. Any ideas?

OS X :: Cursor Keeps Disappearing / Leaving Only Few Black Vertical Stripes

Apr 17, 2010

My cursor (in all forms) on my macbook seems to be disappearing--it appears that every other column of pixels has gone clear as well as a clear border, leaving only a few black vertical stripes as the normal cursor. It's a black outline when it's the hand and it's a few colored stripes when it's the spinning wait cursor.

Interestingly, when you do the ctrl+zoom in a few degrees, the cursor reappears.

If anyone thinks it matters, I was in the middle of backing up via time machine when it disappeared...

Any suggestions are appreciated.

MacBook Pro :: Periodic Vertical Stripes On An Early 2008?

Jun 16, 2012

For about two weeks I've noticed green vertical stripes appearing on my early 2008 MacBook Pro. As you can see the photo below, it doesn't completely obscure content on the screen. The problem is also transient. It appears, sometimes as a flash, then disappears. In the picture below, the issue continued for longer than ever before (about 1 min). Is my video card about to die? Could this be a bad connection?

Intel Mac :: Two Vertical Lines Have Appeared On Display?

Jun 23, 2012

I have recently noticed two vertical lines (seem to be a lighter shade of display screen color) running top to bottom on my desktop. They stay on my display screen all of the time.  This lovely old guy was purchased May 2006  but has every upgrade (except Lion....running Snow Leopard) and full component of memory...serves me well but I need to know if this is a sign I am losing my hardware.

Intel Mac :: 5inch Display Vertical Blue Line Appeared

Jul 6, 2012

Yesterday a vertical blue line appeared on my Mac display, which can be seen all the time but not when it is turned off.I can't make a screenshot off it, you can't see it on them.My Warranty just ran out one month ago.And I didn't used the imac very often, wasn't much gaming or running it the whole day, just using it for school works.Actually I am very disappointed of Apple, bought my first imac because I thought instead of a PC it would last 4 years at least.

OS X :: Unable To Switch Between Apps / System Not Shuting Down

Sep 20, 2010

I had FCP open and I was 'log and transferring' a bunch of footage from P2 cards to my RAID. While that was busy working I was surfing the web in FF and listening to tunes via itunes. I had itunes mini player open. I wanted to see more info about a song and tried hitting the green button to maximize. Nothing happened. So I try command+tab but I get a 'bonk' sound and I don't switch apps. I though it was odd that even when I clicked on itunes the menu bar still said firefox.

Next I did the good 'ol command+option+esc to see if itunes was 'not responding'. this is what I see: Odd... no apps appear here even though I had 3 open not including Finder. So I go to my dock and click on finder and I get this dialog box:

So I tried going up to the Apple icon and chose shutdown. I clicked OK and waited and the machine never shut down. I had to to a hard shutdown. Upon restarting all is right with the world again. It's just weird that I have never run into anything like this in all this time and this new machine as been working perfectly since the day I got it.

IMac :: Unable To Use TV As Secondary Monitor / Switch Between Primary And Secondary Display?

Feb 2, 2009

we are trying to hook up our TV as a secondary monitor (for hulu, netflix, etc) but it defaults as the primary monitor. We would like to keep the imac as the primary monitor, and have the TV as a secondary, but cannot figure out how to do it! The only way we can get the imac back to primary status is if we use mirror mode. Once we take it off mirror mode, the TV becomes the primary monitor again, and there appears to be no way of switching it in OSX display preferences.

I've done similar hookups with my laptop, and the TV defaults as the secondary monitor. Why isn't this happening with our iMac? Any ideas?

OS X :: System Freezes With Vertical Pixelated Lines?

Apr 10, 2010

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).

IMac Intel :: Unable To Turn On System / No Fans Start Up And The Screen Does Nothing

Jan 25, 2007

My parents recently bought an iMac. Yesterday my mom was playing a game when the computer froze. Neither force quit or holding the power button was doing anything so in her frustration she unplugged the system. Today, after plugging in the system again, it won't turn on.

I press the power button on the side of the wireless keyboard and the green light on the keyboard turns on for about 3 sec and then starts flashing. No fans start up and the screen does nothing.

IMac Intel :: Unable To Turn On System / Had Soft Power Down Last Night

Feb 15, 2009

I just bought my Intel-based iMac last night and it took forever to turn on out of the box. I guess I made a mistake by doing a "soft" power down last night, because this morning it will NOT turn on. I've tried using the power button and waiting. I've tried unplugging and plugging it back in, and then using the power button, and waiting. Nothing works. I've been a PC user for 20 years and just bought this, my first Mac, last night. I think I've made a huge mistake! How the heck do you turn these things on????

IMac Intel :: Unable To Turn On System / Shut Itself Down And Refused To Power Back Up

Jun 19, 2008

I have a 20" intel-based dual core Mac which i have had for about since early 2006, i haven't had any big issues with it until a few days ago when it suddenly shut itself down and refused to power back up. I ran through the checklist that Apple Support provides, including resetting the SMC by unplugging everything and waiting 15 seconds or so but none of it worked. Eventually I just left the power cord unplugged overnight and in the morning I plugged it back in.

After having the power cord plugged in for a few hours and the machine turned off, i tried pressing the power button again and to my amazement it powered back on! Immediately i ran the TechTool Deluxe software that came with my extended protection plan (now expired) and everything was fine. Later that night however, I had left my computer on for a few hours before returning to it and realizing it had shut itself off again. Now I am back to where I started, going through the checklist provided by Apple and am really starting to get concerned. Does anyone know of anything else I can do, short of taking it in to an Apple store? Or is something needed to be replaced?
