Imac will not boot. black screen, no sounds.. but has power.

Hi guys, yesterday my mac would not boot. The screen is black, and the power light on the bottom right hand corner is on. My warranty expired 30 days ago (figures). I stupidly put in a CD to see if the player had power and it did (now I can't get it out). I can hear the fan on, and the DVD drive spinning. I have no chimes or sounds. I removed the memory and started the machine... same thing except the power light started flashing. I put the memory back in and powered it up.. same as before solid light, black screen, and no sounds. I unplugged the unit for a day which did not help. ANY help would be appreciated!
Imac - Intel Mac OS X (10.4.9)

First, boot and hold down mouse key to get CD out. then,
Try this.
Turn on Mac and hold down command-S (Apple S), it will boot into single user mode (white on black). Let it finish.
When it is done type the following.
fsck -fy
then hit return. It will check the disk and make repairs. It can take several minutes. If it finds errors it will fix and say OK. If so, type fsck -fy and run it again. This time if it doesn't find any errors type
reboot
Hopefully it will boot into OS X.

Will not boot - Black screen A2 code on bottom right.

mobo:Z97S SLI KRAIT EDITION
Samsung SSD - Windows and games are installed here
WD HDD - Everything else is put on this one.
Windows 7
I installed an ISO mounting program called Gizmo Central onto my HDD
After installation it said that it needed to restart. After it restarted I got a black screen with an A2 code. The screen will go completely black, and then it will back to the screen with the A2 code in the bottom right. It won't boot up BIOS, unless I do 1 of 2 things:
1. power off the pc, unplug the sata cable from the HDD, power pc back on, bios and windows will boot up. I can then turn the pc off, plug the sata cable back into the HDD, and it boots up fine into windows, but if I reboot again, it goes back to that black screen with the A2.
2. I have put in a disc into the dvd drive, and I do not get that screen. (I've been doing this as a workaround since it's much easier)
I have tried a number of things to resolve this, but none of them have restored my computer to it's perfect working order that it was previous to installing this program.
When I tried to uninstall that program it wasn't even on my installed programs list, so I deleted the folder it was in. This didn't resolve the issue.
I have wiped everything off of my HDD drive. This did not resolve the issue.
I have triple checked that my SSD is the first in the boot order. I even disabled the HDD from the HD boot order entirely. No change...
I updated my motherboard drivers. No change.
It's almost like for whatever reason my BIOS isn't listening to the boot order and doing my DVD drive, HDD, and then the SSD ever since I installed that Gizmo ISO mounting program.
I set the BIOS to factory default settings. That did not fix this issue.
I have use a windows system restore point from 2 days ago when it was working flawlessly. No change.
I'm thinking about reinstalling Windows, but logically it doesn't make sense to do that since the error happens even if I power off/on from BIOS with the HDD plugged in, so it I'm willing to venture that it's not Windows at fault here.
Also the computer used to boot up in like 8 seconds. It's still fast to boot up, but ever since this started to happen, it takes like 15-30 seconds for my usb mouse, and usb keyboard to register after windows starts up. It use to be immediate. My computer is so messed up right now, and I don't even know how it got like this or how to fix it. I'm pretty savvy and can follow directions well, so any help would be greatly appreciated.

What intel USB driver version do you use? There's one more thing to try, try plug the kb/ms to USB 3.0 ports except the ones under the LAN port, and check if it happens again.
I'm glad you recommended checking Intel drivers. I typed appwiz.cpl to go to the installed programs list in windows. Found "intel USB 3.0 extensible host controller". I tried uninstalling this. It made my mouse and keyboard not work for about 1 minutes. Windows downloaded some drivers for my devices, and asked to reboot. I rebooted. Mouse/keyboard responded right away! Just incase it was a fluke I rebooted another 2 times, and each time the mouse and keyboard are immediately responsive. I'm SO glad that my PC is back to it's original working order. Thank you to you all for taking time out of your day to help me. I really appreciate it!

You got me there. I only looked at the LED's after it hangs.
I must wait for my reshippment of my memory. I returned it, and asked them to test it. If it tested good, then it probably not compatible with system. My next option was to order GIGARAM 1GB, since it is on the list of recommended DDR.
Sorry, I cannot reboot at the moment. Do you think it is the memory, or something else?

My iMac will not boot up. it brings up a black screen with a cursor

all of a sudden my imac will not boot up. it brings up the grey page with the apple, then instead of going to the login, it goes to a blank black page. The cursor moves with the mouse, but that is it

First carefully read and then methodically follow Apple's troubleshooting steps in Gray screen appears during startup

Intel iMac will not boot past gray screen

Intel iMac will not boot past gray screen
my system:
new (month old) 24" intel imac, 2.8 ghz, 4 gb ram.
running: leopard (upgraded from tiger, which was pre-installed at purchase), installed 10.5.1 update right before this huge problem occurred.
install discs on-hand: two-disc tiget set, single leopard upgrade disc.
what led to this:
i wanted to install windows using bootcamp on a 50 gb partition.
at this point i was running leopard 10.5
i followed all bootcamp instructions, printing out the guide, as well. once i got into the windows setup, i was prompted to choose a partition to install windows. unlike the bootcamp guide, which showed three partitions, one clearly labeled "bootcamp", i saw only one partition. not wanting to risk writing over my mac partition, i quit the setup and rebooted the mac os. after some googling around, i looked for firmware updates (didn't need any), and then software updates. i decided to try updating to 10.5.1.
i then ran through boot camp again, deleting my previous windows partition, creating a new one, and moving forward as before. once again, i was only shown one partition to choose from in the windows setup. i exited the setup again to reboot through the mac os, but this time, i was only given a blank gray screen.
here's what i have tried so far:
booting from a CD, holding down the C or D keys: no response (in fact, i have to restart the computer holding down the mouse button to be able to eject the CD)
booting with option key held down: gray screen
booting with option key held down with external bootable firewire drive attached: the firewire drive appears as a boot icon, and i can click on it within a five second window, but then the screen freezes after that time period, and nothing changes
booting into target mode while attached to another mac: gray screen (no firewire icon, and drive never shows up on other mac)
resetting NVRAM: i'm able to hear the boot chimes, but no difference in performance. gray screen every time
Safe boot: nothing but a gray screen
Verbose mode: gray screen
Single user mode: gray screen
Single user mode with firewire drive attached: occasionally (not every time), i am able to get the white on black terminal to show up. from here, i'm able to run fsck, but it appears to only be checking the firewire drive. i have tried several times to boot from here, and once it took me to a blue screen with movable arrow cursor, but it never went beyond this.
is there anything else left to try before taking it to apple?
any help would be greatly appreciated.
thanks,

I'd call Apple support at this point. You'll need
to put this issue on the record.
Call U.S. iPod and Mac technical support: 1-800-APL-CARE (1-800-275-2273)
The wait may be long for an agent to come on the line
so expect that and have some other stuff to do in the meantime.
If you have the applecare protection plan, I'd ask about "onsite"
service.
I like your work ! Good luck !

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle. I have tried various commands but to no avail. does anybody have any advice?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

IMac will not boot up, all I get is white screen help

MY iMac will not boot up, all I get is white screen?
what do I need to do to start machine please?

Start with a google search for white screen site:apple.com and peruse the many hits.

IMac will not boot, hard drive file problem? Can't install OS in 2nd part.

The iMac will not boot. The Apple displays on the screen, the cursor spins for awhile, and then it loops into a reboot effort.
Last night, I was doing a lot of custom file sharing settings using the include enclosed folders option at the bottom of the Get Info window.
Question 1: Could that file sharing process have messed things up?
In an effort to get things going........ A few weeks back, I used Disk Utility to create a 2nd partition, with the intent of installing Ubuntu Linux there. I never attempted the install, as far as I can remember, while playing with the Ubuntu Live CD. So, I thought I would install 10.5.6 from the CD in the 2nd partition. But I get an error message that says "The installer could not create the folder "/Volumes/Ubuntu 9.10/BaseSystem.pkg.161nDNDdQ.""
Question 2: I also shared that partition, could that have caused the OS install failure?
Question 3: If I understand the book correctly, I can try to install the OS from the CD on the 1st partition, and not lose my data, correct? Unfortunately, I don't have any backup for the data, as I don't own any drives large enough yet to accommodate the data on the drive.
Question 4: Anyone have any other thoughts as to what ent wrong?

Hi, Grant.
Sometimes, it just pays to think on a problem. I awoke thinking, if it will boot the OS X install CD, it ought to boot my Ubuntu Live CD. And then, maybe I can change permissions on the first partition. As soon as I thought that, it occurred to me, if the problems are with the permissions, what if I used the OS X disk, and erased (formatted) the Ubuntu partition. That should set all the permissions on that partition back to default. Would OS X install then to the Ubuntu partition?
You better believe it did!! I'm typing this from the Mac after updating my 10.5.6 to 10.5.8 in the 2nd partition, and I'm booting from the 2nd partition.
I then did as you suggested, and from the Mac, I repaired the permissions to the first partition. But, the result was the same, there are a few permissions that do not match, and Disk Utility cannot, does not, or will not correct them.
I'm currently downloading the 10.5.8 combo update .dmg file. My thought is to burn that to a disk, and then install it over the version in partition 1. And trust that the current installation on partition 1 does not have any cross linked files that will destroy some data.
I do have some old ATA IDE drives I can hook externally to the Mac, and copy some of the information I have from the Mac to those drives before doing the 10.5.8 install.
Can you think of a better solution?

Sometimes iMac will not boot up

hey guys i have been having this on going problem for about a week now. Ok so here's what's happening, this usually happens at night. It seems that my iMac will not boot up, I have my computer put to sleep when I go to sleep and I can wake it up again in the morning. Now when I go out in the evening today for example, I just got home, woke my computer up and everything seemed fine. After a little bit my computer froze so, I restarted it and it will not boot up it would get stuck on the gray screen, sometimes the apple and the spinning thing under it (not the beach ball one) would show up and sometimes I would have just a grey screen. Over the past week I've tried the following:
Reset the Pram
Booted up from the installation cd.
Removed all the cords waited for a couple min. then tried again
Eventually I can boot up, However I am very concerned to what the problem might be.
O yea I also ran a permission repair
One final thing if knows how to protect macs with an anti virus or something similar, it would really help me out.
Thanks

Hi Karim
The symptoms you describe could be caused by bad RAM.
Follow this link to learn about testing memory.
With your iMac you should have received an Apple Hardware Test CD, if not it's included on the Installation DVD (it would state that written somewhere on the DVD). There's also a RAM test included, but it isn't as dependable as memtest (mentioned in the link above) in my experience.
Follow this link to learn how to start the Apple Hardware Test.
Kind regards

IMac will not boot from any mode except Target Disk

I have an Early 2008 Penryn iMac 24" MB398LL/A running OS X 10.7.4 (see specs below) that will not boot from ANY mode, It also has several strange vertical bars from top to bottom on the screen. They are about 10 px wide, with some pixels empty and looks a bit like a barcode if you squint at it.
I have tried Safe Boot, Force Boot, DVD Boot, FireWire/USB Boot, and it always gets to the same point. It gets to the apple screen with the spinning gear and then after about 8 seconds it freezes. The only way it works at all is in Target Disk Mode. It pops right up on my Macbook Pro and I was able to grab all my info!
I have run Disc Utilities and Tech Tool on it many times from my MBP and it passes every test.
I reformatted the HD and installed 10.7 again, it still freezes up at the same point.
I have tried using Single User mode and every time have had to run /sbin/fsck -fy twice because it always says the disk is ok but it was modified on the first pass.
I thought maybe it had a bad video card or logic board but and I ran the Apple Hardware Test on many occasions and it always passes. Recently I was told about Loop Mode and just completed running the AHT for just over 30 hours without any errors at all.
UPDATE...
Strange Part… I tried installing Mountain Lion in Target Disk Mode and everything went smoothly. When it restarted on its own the lines on the screen were gone for the moment, but the Mac still freezes up on the spinning gear and immediately restarts on its own. I have run every thing listed above on it and still nothing. Sometimes the lines reappear then in two more starts they are gone.
I did manage to have it start one time got a copy of the the error report (its at the bottom too) The Mac ran for at least 30 minutes with no problems, then the screen went crazy a few seconds and it became unresponsive. The mouse moved but that was all it could do. Now my iMac continually restarts itself, I don't have any more ideas, HELP!

IMac will not boot up when printer is plugged in USB

After buying my new iMac (with Tiger) I successfully transfered everything from my old iMac (with Panther) and all was well.
The problem is that when my printer (Canon Pixma MP130) is plugged in on start up, the iMac will not boot up (no gears turning on the white/grey screen). When I unplug the printer from the USB and start it up, it works fine. Its not a super big deal because I can just plug the printer in when I need it. But why does it do this?
I foound on the internet someone else who had the same issues. It was suggested to him to search the printer manufacturers website for updated drivers. I did this, installed them etc..... still no luck.
I am without any mac guru's here in Yellowknife......help!

Hello there,
I hope it is OK to recycle this old thread.  I did not want to create a new one since I am experiencing the exact same issue as the original poster *flying girl* as well as other posters in the following threads:

http://discussions.apple.com/thread.jspa?messageID=4470944
I have two Macs, a PowerBook G4 and an Intel iMac 20" (Aluminum)--please refer to my signature or profile for the specs of these machines.  Of course, I got the PowerBook before I got the iMac.  I am running the latest version of the Canon MP130 drivers, printer drivers version 4.8.3 and scanner drivers version 12.11.0, on both machines.
When I turn on my PowerBook with the Canon PIXMA MP130 multifunction turned ON and connected via USB to the PowerBook, the PowerBook boots up just fine.  I have even experimented with both a USB hub and a direct connection to the Canon MP130, and the PowerBook boots fine in both instances.
However, when I turn on my iMac with the Canon MP130 turned ON and connected via USB to the iMac, the startup tone plays, and then the iMac hangs at the blue/gray solid screen--it does not even show the Apple logo or the spokes--that is, until I turn the Canon MP130 OFF.  When I turn it off, the Apple logo appears, the spokes move, and my iMac boots up just fine.  And as long as the MP130 is OFF, I can boot the iMac fine from scratch too.
I tried starting in verbose mode (⌘V) and single-user mode (⌘S), and the gray/blue screen still appears after the startup tone plays; again, if I turn the Canon MP130 OFF, the rest of the boot sequence resumes as normal, and only then do I get to see the descriptive text for those startup modes.  But the text goes by so fast that I miss most of it--I did manage to catch something that said something like "get full config descriptor = NULL," but I am not sure if that was the exact wording.  I would need a good camcorder or even just a digital camera or another device to capture exactly what the screen says in verbose mode.  If I had those options, I would post pictures here.
I was thinking about contacting Canon, but since the issue happens on one Mac only, I figured they would tell me that it is a problem with my Mac.  So hopefully posting the information here is OK.
Another key feature is that the Canon MP130 has a built-in card reader.  I made sure that my Startup Disk preferences were set to boot from the system drive, and they still are.  And I have reset the SMC and PRAM on the iMac.
I would like to mention the following link:
http://www.ehmac.ca/anything-mac/50389-intel-imac-wont-boot-when-canon-printer-p lugged.html
If you go to page 2 on that above thread, it shows one user who allegedly physically disconnected the card reader connection from the inside of the Canon MP130 (I would NOT recommend that myself).  I just wonder if there is a more feasible resolution to this issue.
Does anyone else experience the same issue with other printers or multifunctions?  Also, why does the issue occur only on my Intel iMac 20" (aluminum), and NOT on my PowerBook G4?
Please let us know about your experience as it seems many of us are at a loss for a solution.
Thank you very much for your help; we await!  :)
Cya!

HT1758 Power failure in the middle of a software update and not the computer will not boot up. The computer just has a white screen with a grey apple and just loads non stop.

My iMac will not boot up after a software update. the screen is all whute will show a grey apple in the middle and will look like it is working but nothing happens; this can go on forever.
Does anyone have any suggestions?

Do you have a backup in the form of a bootable clone or Time Machine? Restore that and then try the update again.
Some things to try here (Safe Boot)
http://support.apple.com/kb/TS2570
Another option might be to download the standalone from Apple Downloads on another Mac and try installing it in Firewire Target Disk Mode to the Mac that was interrupted during the update.

White iMac will not boot after 10.6.8 upgrade

I downloaded the 10.6.8 upgrade last night. This morning, the white plastic iMac will not boot.
I have tried evey known keyboard option.
I have tried booting from the snow leopard dvd.
I have zapped the pram.
Nothing!
Please, any help would be great.

We bought 2 iMac's 27inch with i7 Quad-core. Did the update a couple of hours ago. My Mac asked to reboot after update, but i didn't accept and worked with iTunes for a while. Then rebooted manually. After reboot it took about 15 minutes to reboot (light-blue screen with nothing on it, not even a mouse). My Wife also did the update of 10.6.8 and rebooted when asked. Her iMac also took 15 minutes to reboot, bus update was unsuccesful! So did update again and then denied reboot and rebooted manually! (Apple-logo and then choose "restart").
When we did that, iMac was very fast and updateproblem was solved! So deny reboot and reboot manually and problems are over. Same deal with 2 brandnew iMac. I'm guessing this is an issue. To much of a coincidence for me!

My iMac will not boot through Snow Leopard but will boot through Windows OS

My 2010 iMac will not boot in Snow Leopard, only Windows. Have tried reinstalling Snow leopard a few times and works only for a couple of minutes before freezing and doesnt reboot. Windows works perfect. Snow leopard just doesnt want to boot up past the Apple Logo. It was working fine one day and the next day it froze up and was able to reboot back into Snow Leopard but kept freezing. Now it doesnt load at all into Mac OS.

Possible scenarios:
1: The 10.6.3 SL retail disk is bad, it happens.
2: Your not using the 10.6.3 SL retail disk but one from another machine which doesn't have the drivers for that machine.
3: Your optical drive is funky or some other hardware issues.
4: Your trying to install 10.6 onto a PowerPC based Mac, no can do.
5: Your not using a wired keyboard for boot key commands, have some other hardware conflicts.
Possible solutions.
1: Copy the SL 10.6.3 disk using Disk Utility to another DVD, the error checking may resolve the original disk's issue.
http://www.brokenhomeboy.co.uk/pierow/blog/2011/10/make-a-bootable-backup-snow-l eopard-install-disc/
2: Make a SL bootable USB
http://www.maciverse.com/install-os-x-snow-leopard-from-usb-flash-drive.html
3: Call Apple for a new 10.6.3 disk (and make copies for backup before Apple discontinues selling it)
If your upgrading to 10.6 to get to 10.6.8 to upgrade to 10.7, be warned of this:
1: Your 10.5 software will not work in 10.7, no more Rosetta or PPC based code.
2: Your hardware will not qualify if it's a 32 bit Intel Core Duo, also you may experience slowdowns in performance over 10.6 (10.6 is the fastest OS X version for Intel Macs) in older Intel hardware (I suggest Early 2011 Mac's and later only for Lion)
3: Mountain Lion 10.8 is reportingly coming out this summer and will not run on a lot of older Intel based Mac's because of heftier graphics requirements.
4: 10.6 has the widest range of current avaialble software and drivers for third party hardware.
My advice, stick with 10.6.8 and stay there, buy a new Mountain Lion machine after this summer. Skip Lion completely.

Imac will not boot. black screen, no sounds.. but has power.
