Hallo ,I have an IMAC 21.5. which does not start.When i press the power button i hear only beep with an interval of 4-5 seconds.Some times when i take off the RAMS and put them again then get a white screen and shows that i have to insert a bootable device.Then i bought OSX mountainlion on line and wrote it on a DVD and tried with a USB key board to start the DVD.But does not work.Please help me to get this imac work.
Thankyou in advance for your help.
TerrenceHey terremo,
Thanks for the question. From the information you provided, it sounds like the iMac is successfully turning on, however video is not displayed. These symptoms can usually be isolated further by the troubleshooting steps in this article:

I can't turn on my Mac Book Pro. If I press the power button will beep 3 times (won't turn on) stop and beep 3 times again. What can I do?
Three beeps at startup almost always indicate bad RAM. You probably need to get your RAM replaced. Bring it in to Apple for a definitive diagnosis if you are unable to run the Apple HardwareTest

It's new and under warranty. That's the reason to go to the Apple Store.

Hello.
I have a MacBook Pro 13-inch (mid-2010):
Processor: 2.66GHz Intel Core 2 Duo
Memory: 4GB 1067 Mhz DDR3
Running Mac OS X 10.7.2
Yesterday I opened my computer (was sleeping as usual) and the screen just flasehed white and the computer powered off. The magnetic electricity thingy was connected and was green, so it was fully charged, and connected to the electricity.
Since it powered off, I tried turning it on again, and again, one second after starting to boot up, screen flashed white and the computer powered off.
I read somewhere I should hold down the power button longer, so I did, and it booted up. That's why I am able to write this. But every time I turn it off or put it to sleep, it does the same thing when I boot up.
If I don't hold the power button for 10 seconds or so, the computer won't work.
Then today, I did a backup of my entie hard drive, just in case. Later, I started using Excel, and about 1 hour after I was on it, suddenly it got really slow. Like I would click on a program like Safari, and it would take over 30-45 secs to start and be ready. And my computer is usually really fast!
I went on the Internet again, started in safe mode, boot up with option+command+P+R to reset PRAM, and nothing worked. Then suddenly on one turn-off/turn-on (since I can't restart because the computer only starts if I hold the power button for 10 seconds), again it is working at normal speed.
What can this be? Any ideas?
I really appreciate your time and help in advance

Are you running the Apple-supplied RAM? Have you run Apple Hardware Test? I don't know what else you've tried, but this may be time to do a fresh install of Lion if you have not done so since installing Lion. -
Hi, when I press the power button on my MacBook nothing happens and it is driving me crazy If anyone knows how I can fix this problem, I will appretiate it very much
Thank youTry an SMC reset, which can often fix that: http://support.apple.com/kb/HT3964 . Note as you scroll down, there are two sets of directions for MacBooks, depending on whether you can remove the battery or not.

Mac won't boot after I pressed the power button for it to sleep
Ok so, I decided to take a break and instead of turning off my PC, I put it on sleep by pressing the power button...and screen obviously goes black.
After an hour and a half I decided to return to my PC...and on pressing the power button it won't boot (nothing: no sound or sign of life).
Thought it may be due to the battery, however seems like it's fully charged as when I connect my adapter to it, the led light is green....
What am I going to do???? And I don't download or watch films or anything of the sort!!!!!!1. Reset PRAM. http://support.apple.com/kb/PH4405
2. Reset SMC. http://support.apple.com/kb/HT3964

I have a MacBook. It went to sleep and I could not wake it up. I shut it off by holding the power button so it shut off. Now I can't get it to start at all.

My probably 10 year old MaycBook died. It won't start. When I press the power button, it gets power, but it only lights up and a scratching noise starts like something is spinning. A file folder with a question mark periodically flashes... Help!!!
You don't have a Macbook if you are running OS 9 and it's 10 years old. The first Macbook is an Intel Mac that came out in 2006 running 10.4.x. You most likely have a Powerbook. Try posting in the Powerbook forum.
A flashing question mark appears when you start your Mac -
i want to turn my macbook air off. the shut down button already appeared but the mouse/cursor just hang and won't work. even after pressing the enter button to shut my mac off won't work. what will i do?
This is not a reply. I just want to elaborate on this problem.
My computer freezes occasionally when it is used after being sleep for a while. The spinning ball appears and everything is totally disabled. Nothing on the keyboard works.
The mouse moves, but does not work.
The only solution is to turn the power off and on (losing all data in open applications.)
I kept the System monitor running on the side to find out which program was running when the computer froze. The Monitor as well as all other applications froze, but the data showed:
Firefox 18.4%
Activity Monitor 0.9%
Firefox Plugin 0.2%
This is all the information I have. By the way, I am using iMac with OS 10.6. -
My MacBook Air, once pressed the power button, comes up with a file containing a question mark. I have tried re-starting it but this logo continues to appear and will not go. I cannot log onto my mac. Any suggestions as to what this is please?
You need to reinstall OS X:
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless. -

Usually means that critical system files are corrupted. Start by:
Boot into Safe Mode if possible. If it boots into safe mode, then restart the computer to see if it will boot normally. Otherwise, reinstall OS X. Unfortunately, you've not provided any information in your profile about what version of OS X you have installed. -
P35 Platinum: I have to press the power button multiple times to start
Hello fellow MSI customers,
as written in the subject, I have a problem with starting my PC. When I press the power button, the computer powers on, but there is no output to the screen. In fact, my LCD stays in standby mode. I can hear the fans running, so something is going on. According to the LEDs on the mainboard, it is a memory problem.
Now I turn the computer off, using the power button (have to hold it for a few seconds). When off, I start again and everything runs as it should.
After starting, I ran memtest86 multiple times without any errors. I ran a few games, compiled some programs, installed Vista 64bit, Linux, all without any crashes or hangups. It is just the starting that makes problems. After booting it is very stable.
Seeing that it could be a memory problem, I brought another pair of memory, just to be sure. I couldn't reproduce the problem on that day! Any type of memory I put in (the one before, or the newly brought home) the computer always started on the press of the button. So I thought, OK, maybe they were not seated correctly. But, alas, two days later it is again only starting by pressing the power button three times.
What I tried:
1. Boot using only 1 piece of memory stick
2. Boot using only 1 piece of memory, but different one
3. Use another pair of memory <- worked, but on that day it also worked using my original memory
4. Disconnected everything except graphics card, to make sure it is not a power supply issue (minimized power usage)
5. Tried all of the above with a different processor
6. Used another power supply
Any other ideas?
Here are my specs:
MSI P35 platinum
Core2 Q6600
Nvidia 7900GT
4GB V-Data DDR2 800MHz <--- I think this is the problem, any experiences?
Enermax Liberty 400W
a few other things (HDDs, XFi, DVD-RW)
By the way, how can I boot from an external DVD-RW? It doesn't show in the menu when I press F11 (boot menu).
Thank you for any help, muro
And just to let a bit of steam off:
1. I had major problems with the RAID controller (not MSI fault, rather intel) - I put two disks into a RAID 0, then RAID 1 and they always failed after a few boots - member missing on both disks. I was getting angry, so I put them as normal (non RAID) disks and everything is fine since, although no RAID.
2. Installing anything except windows with an IDE DVD-RW is very hard. It took me ages until I got Ubuntu booting (there are guides on the net, google is your friend), and much longer to get grub (boot loader) working. Long story short - if you have multiple disks, use the Linux disk as the bootable, do NOT put grub on the disk where Vista is installed.
3. I have no idea, how to update the BIOS, if I had to. I'm using 1.1 that came on the board. I use 64bit Vista and Linux, none of which is supported to upgrade the BIOS. Any hints how to do it (if I needed to)?Hello,
now today is the day I've finally received my replacement board. The good news first - it DOES work! Yepeeee!
Now some more information:
The jmicron controller seems to be missing - a screen with something about "Marvel" is shown before the intel raid screen. However, it is only visible for a fraction of second, so I cannot read it. I think it detects my IDE DVD-RW so I'm quite certain it's the replacement for jmicron. I won't miss it - it took me ages to install Linux with the jmicron controller.
The problem where I had to restart the computer sometimes because it didn't even post (RAM error) is gone. It boots just fine now.
I had an extremely long first post - about a minute, but after that it boots very fast now.
anyway, regarding some questions around here - the manual states MSI recommends using an 350W power supply. My 400W is more than enough. Please note - it is an Enermax, not one bundled with a cheap case. My cheap RAM sticks also work very well now. I did try them on different boards before, so now I know I just had a faulty board.
In the end, I can only say this: This is my 3rd board already and it's the first one that works well. As the hardware changed, I presume there were major issues with this board that lead them to make a new revision. What is strange, though, is that the revision is still 1.1, as were my previous two. I pity everybody who had the same problems as I did, but I can now say that I'm very happy about the board now.
Cheers, muro -

There are a couple of things that you can do yourself before taking your machine into an Apple Store or an AASP... download and run an application named Rember that will run a RAM test for you - let it run for a couple of hours or even overnight. If it turns out that your RAM is faulty, Rember will let you know. If it is faulty, then you have a couple of options - replace the RAM yourself or (particularly if you're under warranty still) take the machine to an Apple Store or AASP and have them replace the RAM.
If Rember finds no fault with the RAM, then you'll need to take it into an Apple Store/AASP and get a free diagnosis on the machine. Three beeps do usually indicate faulty RAM, but if it tests good with Rember you likely have another problem - it could be something as simple as the RAM, somehow, not seated correctly or signs of another hardware problem.
Run Rember first... call back with results.
Good luck,
Clinton
