my screen keeps blinking on and off every 10 seconds or so and if I let it rest for a while it settles down but everything is missing from the screen except my screen saver photo.
View 7 RepliesThe other day the screen started blinking randomly. It'll flicker for a few seconds and then go white with vertical grey lines for a few seconds. Then it will go back to normal. There doesn't seem to be a pattern to it. Sometimes it will go through that process for five minutes and then stop. Other times I can be working on it for hours and nothing will blink or act screwed up.

The machine wouldn't turn on....I called apple care & we rearranged the ram, now the red light is gone but my system still won't boot up. The white power light blinks every few seconds... the apple store told me sorry can't help because your machine is vintage. Even if my logic board is fried is there a place to buy one on the cheap?
View 5 Replies View RelatedI've had this 2.0 Ghz 1gb ram Macbook since September 2007 and this was the first time I've ever had any problemas with it. So let me start from the beginning.
It all started this year. One day I picked up my Macbook and turned it on and I noticed that the screen was blinking quite a lot... then it started to get worse to a point I got really worried and it started to annoy me. Sometimes I'd boot it and Leopard would be changing my wallpaper every second (it's supposed to change my wallpaper everyday according to what I've setup in system preferences). While blinking the colors would get messed up and when I closed the Macbook and let it on, sleeping, I'd open it and it would be on the blue screen as if I had just turned it on.
It's worth mentioning that I was running a version of Leopard I downloaded from a torrent and had installed it from an external hard drive. So I thought I should try to format the machine, erasing everything and installing a new and original version of Tiger. Once I installed AND got all updates installed as well it was running perfectly. The blinking had gone away.
Yesterday I installed some new updates, booted and used it fine. Today I turned it on and it won't go past the blue screen and the apple logo won't show up as well. My Macbook just won't boot... I've tried booting on safe mode, booting with the tiger dvd on, i've tried resetting the pram and everything else I could do. The apple logo won't seem to appear and the machine won't boot.
First the blinking screen and now it won't boot.
Any other suggestions besides taking it to a support store? It's worth mentioning as well that I live in Brazil and support to Apple computers isn't as great and cheap as it is in the US. I've had this Macbook for less than 1 and a half year.

White MB about three years old. Was watching something on Hulu and HDD started making strange noises and screen froze. Forced reboot and only got white screen. Couldn't even get into single user mode. Got a new WD hard drive thinking it would fix the problem. Put in my backup of the Install Disk (lost the original like an idiot) but all it shows when I hold down the C key is a large blinking folder icon with a question mark on it. Still can't get into single user mode. I may have screwed up the backup of the Install Disk or am using the wrong DVD since I forgot to label it.
View 1 Replies View RelatedI've got a nasty issue with my 13-mo. old MacBook.
I'm pretty sure it's a dead logic board and possibly a dead hard drive, which I really, really, really hope not as I don't have backups of everything on the drive. I just upgraded to Leopard this past week and did a clean install so not all of my stuff is setup yet.
Power adapter and battery are inserted. All 3rd party peripherals and RAM have been removed.
MacBook does not chime at boot. The screen flickers, but stays black. If I hold down the power button then try to let it boot the light on the front right flashes constantly (like when it's sleeping but a faster pace), like a turn signal on a car. I can hear the cd-rom drive whining but everything else is dead silent.
I've done everything here with the exception of calling Apple.[URL]
I've also tried FW Target Disk Mode, but the MacBook drive does not show up.
I've done everything I can think of and I'm out of ideas at this point.
Additionally, there's a cd-rom (Tiger Restore CD) stuck in the drive. Holding down the mouse button during restart does not eject this CD. Where is the force eject button (I see no pinhole)?
I have business documents, emails, etc. that I HAVE TO get off this hard drive. How can I do it? I don't have a 2.5" drive enclosure but if that will solve the situation I will pick one up asap.
I have the infamous bugged model, the Late 2008 Macbook Pro. Famous for its screen flickering on the 9400M Nvidia graphics card. Â
I am currently using the 9600GT Nvidia card, and have some across a few... problems. First of which: Hard Freezing. I know this will happen occasionally, but I had to shut down my computer 3 times in 4 days because of a hard freeze. 2 of the times, the hard freeze was accompanied by my screen just going absolutely CRAZY. Â
Here is a slight example of what it's doing, but it's not exact (since both times it did something different): Â
[URL]Â
Both times, before the hard freeze and flickering, my iStat Pro told me my CPU temp was between 99 degrees Fahrenheit and 103 degrees Fahrenheit. I am wondering if these low temperatures could have ANYTHING to do with the freezing. This problem has just cropped up recently, and I have never had such low temperatures on my mac. I have Fan Control installed because my fans on my laptop weren't cooling off my laptop well enough... the 9600M GT card runs really hot.

I am facing weird problem of screeing going BLUE every five second. I tried checking Hardware using hardware test DVD and it found no issues. Additionally, I verified both the partitions along with permissions verification using DiskUtility. But, the problem is not going. Finally, when i tried to reinstall the OS by inserting Mac OS X Install DVD and pressing 'C', the DVD is being rejected.

Just came back from the Genius Bar at Apple Amsterdam. Both iTunes and iPhoto had problems launching and libraries were not loading. Ruled out hardware problems so they tried installing OS Snow Leopard over my 10.5.8 in a way to keep my documents safe. All went well until halfway it said it couldn't install succesfully. Made a new appointment for in 3 days from now. They would then overwrite the current OS with the new one so i should go home and make sure to back up all my files in the meantime. Problem is that when i came home and started my laptop i got a blank/white screen with a blinking documents folder symbol with a question mark in it! Does anybody know what it means and will i be able to ever make a back up of my documents?

I came home to discover my power cord had died and my laptop turned off due to no power. I used a friend's power cord to turn it on later that night and send some emails. I bought a new power cord the next day, plugged in, and turned the laptop on. It stayed on the gray screen with a spinning wheel beneath the apple logo for a while. I restarted it and it turned off after a few seconds of the gray screen. An empty bar flashes twice horizontally at the bottom before the spinning bar begins.I tried booting in safe mode, but it would just stay on the gray screen. I tried doing shift+command+v and received a message about keys out of order and disk error full, can't repair. I was able to boot from the install disc, and when I click "Repair Disc" I get the same erros. Not sure what to do now?

I somehow got this MacKeeper program popping up on my screen every few seconds. I also think this program is interfering with other programs on my computer. Now my computer runs slower and start up takes a lot longer. How to take this MacKeeper off my computer. FYI, I deleted every know MacKeeper file on my hard drive, still to no avail.Â

View 2 Replies View RelatedWhen I boot up my MacBook Pro (Unibody 17" 2011 model), it maks the CD noise, chimes the apple chime, then shows a grey/white screen. normally, this would progress to a grey screen with the apple logo on it, followed by the login screen, however in my case, the computer seems to just shut down. the fans keep running, so i know it isn't powering down completely. i can't change the volume/etc. after the computer has done this, so i'm assuming it isn't a display issue (also the display flashes white). does anybody know what this sequence of events is a symptom of? i'd really like to get my computer working again.

I've noticed that when my rMBP (late 2013, Mavericks) turns off the display automatically while on battery (as configured via Energy Saver) and I try to wake it immediately, I get a black screen with the cursor, rather than my password/unlock screen. It remains a black screen, with the cursor moveable, for 5-10 seconds or so, and then the password/unlock screen will appear as usual.Â
This does not happen if:I don't try to wake the display/computer immediately after automatic display sleep (e.g., I wait 5-10 seconds and it's fine)I turn off the display using a hot corner and immediately wake the displayI put the computer to sleep by closing the lid and immediately wake it by opening the lidI select Sleep from the System/Apple menu and immediately wake it by pressing a key or clicking on the trackpadÂ
Why automatic display sleep is causing this temporary black screen? I currently get around it by setting the time for automatic display sleep while on battery to 10 minutes instead of the default 3 minutes to minimize the chances of needing to immediately wake the screen. I'd like to keep it at 3 minutes if possible to maximize energy savings, but the temporary black screen is really annoying if I didn't really want display sleep and consequently have to wake immediately.
my Boot Camp install of XP—I successfully partitioned the disk in my new Mac Pro to install XP, but my problem occurs when re-booting to install XP itself. When the machine rebooted the first time to install, it stopped at a black screen with a blinking white cursor, old-school DOS style. Second time when I rebooted and held down Option, it spit out the Windows CD. When I put it back in and it appeared and I tried to select it, it spun up, looked like it was going to work, and then spit it out again, whereupon I got a DOS prompt asking me to put in a bootable volume and press any key. When I inserted the CD, it spun up, but pressing keys on the keyboard did nothing. I tried rebooting again. This time holding option yielded both the Mac HD and the Windows CD (no spitting out!). Taking this as a good sign, I selected the CD and waited. Same black screen with blinking white cursor as last time, no other response, no prompts, never progesses to an installer, pressing keys didn't help.
Has anyone else run into this problem? This is a brand new Mac Pro with the Radeon in it, I have a USB keyboard and mouse hooked up, and it has the latest firmware update.
EDIT: Seems the CD was bad. Slipstreamed SP2 into my original CD and went. Now I just need to get those ATI drivers.
What o I do I have done command, option, p, r at start up etc. I will not go to the desktop.

I am running OSX 10.5.8. A little while ago I successfully Boot-Camped my hard drive and installed Windows 7, but i recently got a new hard drive. I copied over my OSX partition successfully, but didn't copy over the Windows partition. On my new drive I went through the boot camp assistant and created a partition and inserted the Windows 7 disc. But when it restarts, it just seems to hang there- it's just a black screen with a blinking white underscore(_).
I have been told that because I copied over my OSX partition it didn't set up the MBR on the new disk, is their any way to fix this? (besides doing a clean install of OSX)
Are there any software or guides available to help me fix this?
My iMac's HDD is fried. The computer just froze so I decided to reboot it and was presented with that lovely blinking question mark folder. I tried it again (and every time since) I get the good old apple logo on the grey screen with the spinning loading thing, but it never progresses past that.I threw in my old Leopard install disc and it asks me where I want to install Leopard, but the HDD option never appears, nor does it in Disk Utility. So what do I do now? It's Sunday where I am (Melbourne, Australia).I'm not too sure if it's still covered under the AppleCare Protection Plan. Should I take it to an Apple store? I remember when my mouse broke I tried taking it there and they told me to take it to some authorised repair place. I'm not too excited about hefting the iMac to the shops only be told they can't

My screen savers (any of them) only run for a couple of seconds before returning me to the desktop or any applications running before I turn it on.
I've set the top right corner of my screen (expose') to be the Hot Corner for turning on the screen saver.
That works normally, but it just keeps on turning off shortly after =[
Testing the screen savers in System Preferences make it work but I really don't want to go all the way in there every time to turn it on...
I don't know what's wrong.
##UPDATE## I've found the answer to my problem. It lies in an app called Caffeine. I can either click it so it shows an empty cup or update the app to a more friendly version to my OSX and quit it.
I hope this can help anyone in trouble because this is a really understated issue (at least with Snow Leopard! since it has compatibility problems with the old Caffeine app).
I am using a Mac Mini with a Realtek USB wireless dongle to connect to the internet. The software and drivers appear connected perfectly and i see the wireless utility and I can access my wireless network, which says signal strength 100%. I connect to it and it accepts the wireless key. Says connected. Then after a few seconds the connection is lost and it says 'Disconnected'. A few seconds later it connects then disconnects and this continues indefinitely but Safari never allows me to access any webpages.Â
