OS X :: IMac 2007 Aluminum RAM Installation - Get Black Screen With 2 Gig Stick
Sep 8, 2009
I bought my aluminum imac when it was released in late 2007. I had a 1 gigabyte stick up until now, but I decided to upgrade to 2x2 gigabyte sticks. When I took out the 1 stick and placed the new ones in, my computer would sound like it turned on, but the system really did not boot up. I have tried many configurations to see what the problem with the RAM is, and all I could figure out is that the computer will only boot up if the original 1 gig stick is in one slot. I checked both sticks with this, and they seem to register on my mac when I check the "About This Mac" section. Basically, I get a black screen if I use only a 2 gig stick, or both 2 gig sticks. I can have a maximum of 3 gigs so far, but I really would like all 4 that I paid for. I'm not so sure that it's a problem with the ram, especially because it is recognized by the system, but it can't boot up the system, so I am simply dumbfounded. Anyone have an idea what the problem is? I just recently installed Snow Leopard prior to getting the RAM if that has any importance.

I have an aluminum Intel (2007) iMac and I have had it for two years now. I love my Mac and would never go back to a PC now, BUT (you knew that was coming) I have recently (unfortunately I don't know exactly when) developed a problem in that my iMac will not auto sleep. The screensaver will kick in OK, but it will not go to sleep on its own. I can put it to sleep from the menu manually, but not by the setting in System Preferences. I have reset the PRAM, and the SMC and neither of those changes have worked. Have any of you had this issue and solved it?

I recently bought an used iMac (was purchased new in feburary 2009) in which I knew the screen was not showing any video when I bought it. ( I was okay with that I thought I'd give it a go at fixing) well the problem seems to be within the LCD itself. When I hit the power button I hear the chime, fan spins, and the hard drive does it's thing. I ended up taking the casing off the iMac to where it only shows the bottom half of the insides underneath the LCD. My question is now to diagnose what exactly is wrong with it by using the 4 led lights. I have searched the forums and the Internet up and down for which ones mean what but I have only found out information on older iMacs. When my iMac is off (still plugged in) LED 1 is on. When I turn the iMac on LED 1,2, and 3 are green. Which that leaves the 4th LED not being lit up at all. I suspect this has something to do with the iMac not showing any video but as I said I am not sure because I cannot find any information on it anywhere.

My MacBook Pro from 2007 has recently been having a problem where the screen will go black without warning. It's been getting progressively worse, staying black for a few minutes, then staying black for many minutes, and now it can't be woken up (writing this on yet another computer!). I had a similar problem with an iBook from way back when, but can't remember whether I solved the problem by some series of keystrokes or by buying a new computer.
I tried [Apple]+[Option]+[P]+[R] until it start-up chimed, then start-up chimed again. And I tried holding [SHIFT] while it rebooted. I can hear the volume increase and decrease popping-like sound and it reboots fine (as far as I can tell). This MacBook Pro runs Snow Lion (I think).

My 2007 MacBook is starting up and making all the right noises but the screen stays black - looking on different forums it seems likely it is either the back light or the inverter that need fixing but in the meantime there is some things on there I need - I have an IMac as well and I have tried to connect the too so that I can view the macbook on the imac - I used a firewire cable and held down the t key on the macbook (but obviously couldn't see if it had worked) I then turned on the Imac and held the option key down but it only give me the IMac HD to start from and not the Macbook

I have been given a 1.6 Dual G5 running 10.3. I tried to upgrade to 10.4, the first disc installed but crashed several times on disc 2. I had run DU previously to check there were no problem. Each restart took me back to disc 2 which failed to install. I then tried to install 10.5 (Leopard) booting directly from the disc, it started then crashed leaving a black screen with the following promt:
local host:/root* (a hash not an asterisk!)
Anybody offer any suggestions as to what I should do?
Information:
G5 1.6 Dual

So my girlfriend boss wanted me to fix her computer. So I brought it home turned it on, and it didnt chime but it booted to the gray screen with apple logo/ slashed circle/and folder with a "?" So I made a USB Mac OS x bootable drive (FLASH) held down alt (try using a windows keyboard its fun) was able to select option and install a fresh copy. all seemed well was running really hot so I poped of the screen. HOLY MOLY! this thing is CAKED with dust, and I am not kidding it has literally piles of dust. So I ran updates, and did firmware updates. Turned it off for the night.
The next morning I went to radio shack and got Dust remove spray, opened it up made sure I was carful taking off the screen, and blew the sucker out. now its NICE and CLEAN. then i made sure I plugged everything in and turned it on. Drive spun like normal, Optical checked for a CD, and fans are also running normally. but no chime, no nothing stays as silent as normal but doesnt budge, it is like it hangs.

I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?

I have a classic mac pro and I restored Snow Leopard on my 8gb usb stick.
The stick is recognized on osx and works very well and when the installation process reboots, nothing appens, the usb stick is not recognized on startup, even with the alt command.
I tried on other machines and everything is going perfectly except with my mac pro.
Can you plz guys tell me how can I make my mac pro (classic) recognize my usb stick on startup ?

I've got this older iMac but it has 2 GB and few weeks ago I managed to install Lion on a second partition of the internal HD. Sometimes the computer would hang or cause problems and I decided to install the whole system from scratch. After several failed attemps I finally figured, that the internal HD had a defect. So I decided to use an external usb drive to fix that problem for the beginning and before I think about changing the internal hard drive. I created 3 partitions with a GUID-table on the external usb drive and managed to install Leopard on the first partition and so far it's working fine and I boot from that external usb drive.
Now I wanted to install Lion on that computer. So I took that Lion thumb stick I purchased from apple and pressed the option key during boot in order to select booting from the thumb stick. It worked for the beginning and a message like "Installation" appeared. After a while the installation would stop with a message like "an error occured during installation, please try again". I did this two times but it never finished the installation.

A friend of mine ran into the most surprising thing when he booted up from his MacBook. Instead of seeing the Apple logo, he saw a question mark - ?.
I told him to try and boot from his Install Disc 1 and it managed to as the Apple logo along with the busy progress bar was shown. Then the usual language selection. I told him to select startup disk from the utilities menu and he said that all he could see is network startup and the Mac OS install disk. Even when he tried to repair disk, it said that it wasn't mounted.

Wouldn't that have been more impressive than that razor blade thing they're calling the MacBook Air?

I'm trying to play counterstrike on this laptop and it doesn't seem like 1GB RAM is enough. I looked it up on apple and it says this macbook only supports up to 2GB RAM and comes with 1GB RAM (two 512MB). Do I need to purchase two 1GB RAM or just use one 2GB RAM? Also, is there any specific brands or models you guys can recommend me?

Let me start by saying I have swapped the ram in the computer and the problem persists. I've also tried resetting the PRAM. I have unplugged all devices except the keyboard and mouse. I have reformatted and installed OS X Leopard, Tiger and Snow Leopard. I have even encountered this issue while the computer was running from the install disk. I'm pretty sure software, ram and third party devices can be eliminated from the possible causes. The computer continues to run after the screen goes black. I am connected to it right now using screen sharing, so I know the computer is still working. Putting the computer to sleep and then waking it up temporarily brings the screen back until its next random blackout. I have opened the computer to replace a dead HD, so I suppose it is possible that I knocked something in the process, but I did that back in December and the problem is a relatively recent development. I would really prefer to fix this myself, if I could only figure out what the problem is.

I have been experiencing some unusual problems with my imac. While on the internet today my computer crashed on me twice, the first time the screen just showed a bunch of vertical lines, the second it flashed some random colors then went black. After the screen change the computer was unresponsive. I have a bad feeling, is it due to overheating, a bad logic board or something else. This is the first time I have ever experienced this on a mac. Has anyone had any simiar issues? Or am I up **** creek? I can't really afford a new computer seeing that I just bought an iPad (it comes Saturday). I am not sure if my computer is still under apple care and even if it was I won't get it back by the time I have to go back to college. I attached a screen shot of my computer temps.

When I turn my Imac, it goes from the white screen to a black screen, then blue and then desktop. The whole process is fast, but is not normal. (at least is not like my previous MBP or the videos that I have seen on youtube) At the black screen stage, I can see some boot up information, etc, It is fast so I am not able to read it all. It looks like when booting an old windows or dos machine How can I change this? Is this normal? It also shows the screen when I shut down.

I have been limping along for quite some time with a recurring problem with my PPC Flat Panel iMac G4.Sometimes when starting up I would get a black screen. The unit chimes at startup but the screen would stay black.I found that I was able to fix (temporary) the problem by removing the bottom plate and pushing the reset button under the base.(After shutting down and unplugging the unit.) after the startup chime, the screen turned gray with a folder icon in the center with a blinking question mark.After shutting down and restarting, this happened again 3 times.On the 4th shutdown/startup it went back to the black screen.Repeated shutdown/restarts have no effect.Shutting down, unplugging the unit and pushing the reset button is also having no effect.I hear the startup chime every time. Black screen every time as well now.

There's some known documented issues concerning the Nvidia graphics chip in the particular model of macbook pro I have.
Basically when turning on the machine, the screen is filled with black & white horizontal strips like a piano keyboard, but thats it - it doesn't actually boot up fully at all, you cannot hear the hard drive running !
Would the hard drive have anything to do with this ?
I explained this to apple telephone support & they informed of the article
[URL]
[URL]
& stated that the symptoms were linked.
On taking the mac to an apple store they ran a special 'firmware' boot up 'test' using an instore ipod to determine if it was a faulty Nvidia chip, so as to prove to Nvidia, the company funding the repairs whether it is that to blame.
Because the machine didn't even boot up & complete the 'test' they couldn't say whether it was the graphics chip - so 'no free repair' under extended warranty & the final answer was as usual ' buy a new logic board' that will cure it !

The screen randomly turns black without any major reasons. It doesn't seem to be a sleep mode/screen saver thing as the music continues to play on. I can adjust the volume or pause the music with the keyboard but the screen just won't turn back on. I have to shut it down using the power button and it happened several time the last couple days. Anyone else experience the same thing and got a solution?

I decided I was going to install XP on a bootcamp partition tonight and everything went fine until I installed the Bootcamp 3 software. After installing the Bootcamp drivers the machine rebooted and I ended up with a black screen in Windows. I did hear the XP welcome music so I figured it was a display driver issue. I rebooted into safe mode and deleted the ATI 4850 driver and restarted. After removing the bootcamp driver everything was normal again other than the fact that I only had the default Windows drivers running.
What am I doing wrong? I installed XP off of an XP disc with SP2 already on it and ran the Bootcamp install off the Snow Leopard disc. Finally, not sure if this matters, I am running one of the new i7 iMacs.

This just started yesterday (May 31st). I keep everything updated as it comes out and nothing new has been installed in the last couple of days.
When I need I wake up my iMac (now requiring a keystroke or mouse press instead of just moving the mouse), the screen comes up black, but the cursor is there and moves around fine.
It stays black for a while (15 seconds or longer, but it feels like forever) and then it finally comes up completely.

The screen/crt of the imac that I have been using since about '98 went black - this actually happened a couple times previously but I was able to get back in (no idea - one of those things where out of frustration you just start pushing everything at once and it suddenly pops back on). I have tried everything - the internal battery, that little button on the motherboard (not sure if that is what it is called) that resets everything, the connection of the main power button on the front, etc. I am fairly sure it is stuck in sleep-mode or something (no beeps, hard drive doesn't make the usual booting-up sounds but you can tell that it is receiving power) but after months of wasted effort I finally gave up. I bought another slot-loading G3 and would like to swap hard-drives between the two - I have taken my old G3 completely apart so many times that I am totally comfortable with that aspect but have hesitated because if I somehow blow this one I will be left with nothing.
