Computer will not boot up but fan will turn on and stay on.

I have a Gateway and I did not have enough memory.  I bought 1Gig to give it enough memory to run the basic systems.  I added the memory to the slot in the hard drive and now it will not boot up.  The fan just turns on and runs.  I took out the new memory and it does the same thing.  No working computer.  Need help on what I should do besides Punt.
Thanks,

First and foremost, recheck all internal connections to make sure you didn't bump something loose while replacing the RAM. I had the exact same thing happen to me once before only to find that I had accidentally loosened the cable to the hard drive.

  • When I turn on my MacBook Pro will not boot up but it will have the loading gear revolving and the apple symbol is crossed out

    After installing ProTools 10 and I have a drivers I tried to restart my MacBook Pro, but it will not boot up. It was just working fine and I restarted it because I ran a java upgrade and it will not boot. I tried to cold boot it, but it still allows me to login in pass the encryption login the the loading symbol keeps revolving and doesn't stop.

    If you've activated FileVault, only the users that were authorized to unlock the startup volume will appear in the pre-startup authentication dialog. Once the system has started up, all users will appear in the login dialog.
    To authorize more users after the volume has been encrypted, select the FileVault tab in the Security & Privacy  preference pane. Click the lock icon in the lower left corner and authenticate to unlock the settings, if necessary. Click Enable Users...
    You should only enable users whom you trust implicitly with all data on the system, not just their own data.

  • Mac will not boot up, white screen with turning gear for hours on end

    mac will not boot up, white screen with turning gear for hours on end

    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 boot failure is to secure your 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 your last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
         a. Boot into 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.”
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot 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.
    c. 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. The easiest way to deal with the problem is to boot from an external drive, or else to use either of the techniques in Steps 1b and 1c 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 boot 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 boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot 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 booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
    Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to boot 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 your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you boot 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, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
    If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot 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 reboot as usual (i.e., not in safe mode.)
    If the boot 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 your 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 reboot as usual.
    Step 9
    Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 10
    Repeat Step 9, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
    Step 11
    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 boot 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 12
    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.

  • T60 will not boot - lights, but nothing on the screen, no beeps

    Hey everyone,
    My approximately 4 year old (and thus out of warranty) T60 is having trouble booting. Sometimes, but not always, when I press the power button I get the lights turning on, but then all but the power (Z in a circle) indicator and the battery (if I have it in - I've tried it with and without) and the power cord (if that's plugged in- again, tried every way) lights stay on. Here's a video of exactly what's happening (made by someone else):
    http://www.youtube.com/watch?v=Pm4Lklr6-Rk
    It just sits there and nothing comes up.
    I've tried the following and still had trouble booting:
    Removing each of the two RAM modules (I have a 512 and a 2gig stick) - I would leave one in so that it would work, but I tried it with each.
    Removing the hard drive
    Removing the optical drive
    I also opening it up to see what I could see, but there are no clearly loose connectors. The fan starts just fine, but then turns off shortly after I press the power button. The harddrive also seems to spin up, but the indicator doesn't flash for very long before the lights return to the configuration I mentioned above. There are as far as I know no beeps, though I had beeps disabled in Windows (not sure if that matters at the POST level though).
    However, it does sometimes boot up. I can't tell what exactly makes it work sometimes and other times not. When it does boot, it is extremely stable and works just fine. I'm tempted to just leave it on 24/7, but I'm on vacation and will have to turn it off at least to get through airport security.
    The last time, I tried holding the power button down for about a minute with all power sources disconnected, and it did boot up, but that may have been coincidence.
    I've seen some threads that make it seem like perhaps this problem might be related to the USB ports (http://forum.lenovo.com/t5/T400-T500-and-newer-T-series/T400-won-t-boot-can-t-access-BIOS/td-p/20280... but visual inspection doesn't reveal anything wrong with them.
    Any ideas? I'm leaving it on as long as I can now, but I can play more with turning it off and trying things once I get back home in a few days. It's frustrating, since once I get it to start up, it's more or less solid and Windows and all peripherals seem to run as expected.
    Thanks!

  • Mac Pro will not boot, constant loud fan noise and nothing else

    hello,
    earlier tonight,i put my mac pro on sleep, then later on, when i wanted to take it off sleep and use it, it made the loud fan noise, which it always does but goes away, but this time it the fan wount slow down and the loud noise stays and i dont see anything on the screen. im guessing the fan noise is the ATI x1900 card...
    any help please..i just bought it 2 months ago...

    Hi, here are the steps I would go through. I would unplug the Mac Pro completely from everything and look at the video card's fan intake to make sure it isn't plugged and just make sure everything "looks" correct. I would then plug the machine back into one monitor/keyboard/mouse (leave all the other peripherals disconnected. Once that is done push the power button. Does anything happen? If not then if you have another mac and an external hard drive, make a copy of the OS on the drive and see if you can get the Mac Pro to boot off that drive. If the video card doesn't work then it will not show anything when booting off an external drive. If the external boot does work then I would suspect that you have a bad hard drive (or it crashed). At that point I hope you have a back up of all your data and such.
    Mind you these are steps I would go through. What a nightmare. One other thing to check, make sure your monitor didn't die.

  • My imac will not boot- it gets stuck on blue screen and will not go any further

    Since the last update to Snow Leopard- My computer seems to perform fine, but when I restart the computer or shut it down and then turn it back on- it gets hung. SOmetimes I get the You need to restart screen. But, most times, it goes to the blue screen. The mouse shows up and the dissappears. It shows back up and the dissappears again. Then the system working spiral comes on and off every few seconds. But- it never gets to the sign in screen. ANyone know how to fix? What am I doing wrong?

    Does your iMac fail to boot every time or only some of the time?  Here are some things to try:
    - Boot into "safe mode", which will run the equivalent of Disk Utility's "repair disk" operation.
    - Boot from the system install disc that came with that Mac with the "D" key held down to run the diagnostics.  Run them several times to see if any hardware problems are reported.
    - If you can't identify the problem or fix it any other way, download and install the OS X 10.6.7 "combo" updater.
    - If that still doesn't help, try reinstalling OS X 10.6 over the top of what's on the disk.

  • MacBook will not boot after iTunes 10.5.2, iPhoto, and Safari update

    My MacBook (mid 2007) will no longer boot after the iTunes 10.5.2, iPhoto and Safari update. It will load Lion but will no open any applications. After running Repair Disk Permissions and Repair Disk in the Recovery HD, Lion will ask for my password, log in, then display the menu bar and a grey background and remain unresponsive. I tried downloading a new copy of Lion in Recovery HD but it will not get past about 1/8 of the download bar before freezing and becoming unresponsive. Any ideas?

    Any ideas?? I really need to see if this is fixable! Thanks!

  • My iMac 10.5.8 will not boot or restart, until I power off and on

    My iMac will not start up when shut down, or awake from sleep.
    To get it to start i must turn off the power, and turn it back on, then it starts up and runs fine.
    If i Restart it, it switches off, and will not power back on. The machine still works great but is begining to be a pain in the back-side cycling the power every morning.
    I have done an SMC Reset, and that did not change it.
    I have also added a new user, and when i logged in as the new user, it did restart a couple of times (cannot remember the exact amount) and then when i switched back to my normal account it restarted fine... i assumed it was fixed... but after that it's gone back to it's old painful self..
    Any help would be appreciated, thanks
    BG.

    I just installed snow leopard yesterday through a disk I brought from apple., I had to keep the mouse moving during installation because every time it started sleeping I would need to cycle power which then restarted install!
    I don't think the install fixed it because updating to 10.6.8 required a restart, and it wouldn't restart again. Painful.
    The machine runs fine while it's running, never crashes, performance is fine. It is my work one so I won't be on it again till monday. I will try the repair advice then. I just accidentally selected that it solve my problem (on my iPhone trying to scroll up!!) please ignore that

  • Will not boot normally, but will boot into Safe Mode... what now?

    Hey y'all, I've got an iBook G4—purchased in 2003—that's had its hard drive replaced (due to the OE one failing) and that's on its second battery (which will need replacing soon unless I can't get this resolved, then it's new computer time... ugh).
    Last night I left it open and on and probably had a couple of sites open in tabs in Safari, as well as Mail and iChat open (Preview might've been open, too).
    When I went back to it this morning it wouldn't come off the black screen (I don't have it set to sleep), and I thought it was because it's dry here and I must've discharged into it through the trackpad (though I've always felt it before), which freezes it, a problem that's happened before and that's normally resolved with a restart. Confirmed it was, indeed, frozen by turning the number lock on and off (which turns the light for it at the top of the keyboard on and off).
    Powered it down by holding the power button. On restart it wouldn't go beyond the black screen. Tried it a couple of times, same problem. Things were pretty warm, so I let it sit for a while. Went back to it and it would freeze on the gray apple screen with the progress "gear" freezing after a few seconds of whirling about. Managed to get to the UN/PW screen once, but it froze after entering my UN and PW. Now it freezes on the apple/gear screen every time.
    I used the Hardware Test CD to check things and all the hardware tests showed up fine. Booted it into Safe Mode and ran Cocktail. Rebooted, no joy.
    Booted again into Safe Mode and backed it up onto an external HDD using CCC. I had done a clone a few weeks ago, but I wanted my most recent emails, etc.
    Used Disk Utility to repair permissions. No change. Attempted to boot from my cloned disk image. No go. Repaired some permissions on that drive and tried again. No joy.
    The thing "works" in Safe Mode, but I cannot get it to boot into things normally.
    Seeing as it was online, is it possible that I picked up some corrupted font that's causing these problems? Got that idea from other stuff I've read online regarding iBook G4 start-up issues and this: http://support.apple.com/kb/HT1564?viewlocale=en_US
    Any other ideas?

    Gents, truly, thank you.
    In safe mode I couldn't disable the Airport card as it was already off and the hardware was "not found". No biggy. I simply pulled it. Booted up normally without a problem several times.
    I swapped in a known-good Airport card from another iBook G4 and put this one's in that iBook. That computer wouldn't start and this one started up no problem (and I'm posting from it).
    Weird that it would go bad like that, but it did. It's nice to know what the problem is and that the fix is easy. I'm glad I didn't go through any restore or wipe and install procedures.
    So, again... THANK YOU!
