Should I get a POST screen with barebones?
Got a new barebones Wind PC Nettop, popped in RAM, attached known working (but old) VGA monitor (Compaq 460P, built 1994) & keyboard, powered on.
Blue light on in front. No VGA image.
Popped out RAM, did same, and still no VGA image (nor signal, as far as I can tell).
Removed keyboard - no image.
Should I be seeing anything? Is there a minimum spec for the VGA monitor that I need to have?
Thanks!
Henry
Got a new Wind PC.
Popped in RAM from MacBook I upgraded. Is labeled:
NT512T64UH8B0FB-3C 0747.CN
512MB.2RX16.PC2-5300S-555-12-A2.667
M207B210ED.X2
Tried 2 different SIMMS of the same kind.
Machine never goes into POST. (Doesn't go into POST without RAM, either, but I'm assuming it needs RAM to go into POST.)
Any reason this RAM wouldn't work? I thought it matched the specs.
Nothing else is in the machine. I did both the JBAT1 trick and remove the battery trick just in case there was something wrong with the BIOS settings. Still no POST.
(The front blue light does come on, and the fan always kicks in immediately, even though it is a cool 60 degrees in this room.)
Thanks!

When I burn my imovie I get the IDVD screen with a thumb size video playing in the corner of the screen without audio - weird
You can find the serial number either in About this Mc in the Menu bar under the , or it should be on a sticker under the foot of the machine.
If you have the install discs, try booting from them, holding down the c key and then using Disk Utility to check the drive.
You can also boot into Safe mode
To start up into Safe Mode (to "Safe Boot"), do this:
1. Be sure the computer is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, press and hold the Shift key.
Tip: The Shift key should be held as soon as possible after the startup tone but not before.
4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
Please post back with results,
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup. -
Upon start I get a blue screen with B817977E
HP Photosmart C8180-all in one. I use a Mac Pro laptop. I updated the driver 4 years ago to my Mac. This year while in Fl I went to turn on the printer and I get a blue screen with the number B817988E on the screen. I haver tried re booting by unplugging both ends of the printer cord, but this does not work. Holding the on button in does not work. If it does come on My computer connects wirelessly, but does not print. Then it will not shut down.

on start up i just get a grey screen with the apple logo-this has suddenly started happenin. Please help?
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
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 a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
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 in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is 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. -

Was wondering if anyone can help...I am not very computer friendly but want to be able to edit my photos, use them as jpegs, order prints etc. When I double click on a thumbnail ( am presuming the thumbnails are the small photos ) I get a grey screen with an exclamation mark on it. I cannot drag the thumbnail onto the desk top it just pings back. This doesn't happen with all the thumbnails and has been a problem since we upgraded to snowleopard. I recently reinstalled photos from the memory card from my camera and they are alright. I am presuming that the old photos are stuck in there somewhere if only I knew the right buttons to press to get them out. Thanks, Jane Thomas
Easiest: Restore from your back up.
Otherwise:
Try these in order - from best option on down...
1. Do you have an up-to-date back up? If so, try copy the library6.iphoto file from the back up to the iPhoto Library allowing it to overwrite the damaged file.
2. Download <a href="http://www.fatcatsoftware.com/iplm/"><b><u>iPhoto Library Manager</b></u></a> and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.
3. If neither of these work then you'll need to create and populate a new library.
To create and populate a new *iPhoto 6* library:
Note this will give you a working library with the same Rolls and pictures as before, however, you will lose your albums, keywords, modified versions, books, calendars etc.
Move the iPhoto Library to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library on your desktop and find the Originals folder. From the Originals folder drag the individual Roll Folders to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption. -
I download a suggested "update" from the App Store for my iPhoto yesterday. Now when I try and open my iPhoto, I get a grey screen with the rotating circle icon in the middle......that just keeps rotating. Ergo, it won't open!!! Before the "download" all was fine in Heaven & Earth....now, I'm a little peeved.
Anyone have a suggestion?
Thanks,
Wayne K.
ps Have a good day, God Bless America ...............and be weary of iPhoto update downloads,very weary.No need to be wary of iPhoto updates however it is a good idea to follow the instructions when updating. I haven't updated iPhoto from the App Store before however it should not be much different than doing a DVD update. Here are instructions on updating the library:

Hi, I am not able to reboot my Mac desktop.
When I switch on the Mac, I get a white screen with the Apple logo and the little rotating circle.
The system refuses to boot.
What can I do?
MarcusWe need to get you moved. This forum is for mini-tower Macs built between 1998 and 2005 and doesn;t get as much traffic ("eyeballs on the problem") as the forums for newer Macs.
Please do "About this Mac" from you Apple menu and tell us what that says for "processor" and Mac OS version. Looks like this:

With that we can figure out which of the two iMac forums you need and get the Hosts to move your post. -
When I try to enlarge pictures in iPhoto I get a black screen with an triangle with a "!".
My iMac hard drive crashed and I reloaded Lion and applications including iPhoto. I reloaded the iPhoto database from a backup hard drive. When I open iPhoto I can see my pictures in their events groups. However, when I try to enlarge them I get a black screen with an traingle with an "!". How do I correct the problem.
The ! turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

hey guys. my macbook air wont get past the screen with the apple on it during start up. how do i fix this? i have a paper saved on my laptop on need to get at it. thanks guy!
Your boot drive is damaged in some way. If you have an original installation disc, you can boot from that and run Disk Utility. From DU you can select your internal hard drive ("Macintosh HD" is the name Apple puts on it - you may have renamed yours) and select "Verify Disk". If errors come up, try "Repair Disk". If it repairs, then you should be able to restart and boot from it. If it doesn't show up or won't repair, your drive is probably hosed.

At Apple Store, if you have AppleCare +, replacement iPhone 4S costs $50, if no +, then it will cost $199. Either your battery is faulty, the power management is faulty, or the charging port is faulty, or all three. Start with battery replacement. If still problem, then try charging port with flex cable replacement. If still problem, then it is very complex fix or no fix at all possible.

I did the back up as instructed... Installed a larger hard drive and followed the restore instructions... Now I get a white screen with a folder icon and blinking question mark. When trying to set startup with new drive I get a bless tool error... Help!!
If you have installed a new hard drive , you will need to have formatted it in Disk Utility correctly. This may explain your problem.
Boot into your 10.6 Install disk again at the top menubar > Utilities > select Disk utility and in there select your new hard drive, and select the tab Erase and choose to make the format as Mac OS Extended Journaled. When that is finished look in the main window to make sure that the partition map scheme says GUID Partition Table.
Now go to the Restore tab and reinstall from your backup. -
