Start button lites up, then nothing, any thoughts?

I have a G4 1.25 dual running OS X 10.3.9 with 1.75 GB RAM and a second internal drive WD caviar, 120 GB. Today when I attempted to power it up the backlight on the power button lit up briefly and then nothing, no fan, no drive spinning no nothing, displays black, the lite just goes out as quickly as I release the button. Yesterday it was running fine, no wrong dates or anything like that. I had a low space warning regarding the start up drive while running FCP 3 but dumped about 20 GB of media out of iMovie and it seemed okay. any thoughts?

Here's the power supply instructions.

I did notice a tiny blue lead in the corner of the door which was just dangling loose, it was retained in a u shaped cut out in a small tab of sheet metal standing up at 90 degrees to the door, is that blue lead supposed to be loose?
I believe, based on your description, the sheet metal bracket is for installing an Airport card & the lead is for connecting the antenna to the card.
Do you know a link for how to reset the boards and check out other type stuff?
The G4 originally came with Apple Hardware Test software on the system DVD.
best way to clean up the inside of the machine, lots of dust, looks like the foam behind the intakes is crammed full of dust.
Get canned compressed air to blow off the dust. Don't use a vacuum cleaner because static electricity could damage the electronics.
The max OS is Leopard 10.5.x.

Aperture import plug-in won't run. After examining my library the number of image files stays at "undetermined" and the import button stays greyed out. Any thoughts?

Others have the same issue, with the import button being grayed out. My trail copy expired, but I believe by poking around in the options and selecting another Aperture library and re-selecting, I was able to continue.
The problem is common enough, that hopefully Adobe will address. In the mean time, try repairing your Aperture library, checking permissions, exporting a subset of your library for a test, or try putting that library subset on an external drive. (Can usually avoid permissions issues.)

Logic Wont Start - Icon Bounces Once then nothing

Hi All, really hoping for some help here as I am freaking out and can't get my logic pro 8 to open.
The only thing I have done to my mac since it last worked was installed SampleTank 2XL, which should not have caused a problem. So just in case it was the issue I uninstalled it again.
I have ensured my computer has the latest updates.
The icon just bounces once, and then nothing, no error messages or anything to help me work out what the heck is happening.
Hope someone might be able to help.
Thanks
Brett

Agreed. Download Appcleaner http://www.pure-mac.com/diag.html#appcleaner
Drag the Logic app on it, and reinstall (just the app) after deleting.

On restart I get the expected boing start up sound and then nothing

Was using the computer just fine. When I rec'd the software update notice, I clicked OK, and upon restart, I get the boing sound and then nothing. A black screen. Is this the mother board? Hard drive? Something else?
Thx

I never just install an update when it presents itself.
Some common tips and recommendations:
Reboot - even in Safe Mode
Close all programs at the least and don't run anyting
Backup and clone your system
Repair your system and clone with Disk Warrior first
Use the combo update whenever possible
Apple has improved the updater and process with 10.5.5+.
When you ask us, I prefer to see "I installed (fill in blank but "security update" or quicktime or whatever it was you actually did).
Some would also recommend running Repair Permissions first.
"Normally" it should work. In real life, we need preventative medicine.

I cannot use yahoo or google search engines. i have used several different antispyware,malware and virus scans but have found nothing. any thoughts?

ask.com works fine but i cannot use any search engines related to google, yahoo and several other sites that use those engines on there page. several pages hostred by google also do not work. i have tried several scans to find issues but nothing. i have updated firefox and i have also tried to reinstall firefox twice.
i have also had several issues streaming video or music which wasnt an issue until i started having the google issues

Just saw this: http://support.mozilla.org/en-US/questions/944193
I contacted Rapport and tehy seem to think that this is updated in the latest version (even though ht econsole said I had the latest version) so will give it a try. Fingers crossed

I have a pavillion dv6604nr and it will not boot. the disc drive lites and then nothing.

i was using the computer and all of a sudden my screen looked like a candy cane horizontally. i took out the hard drive and still could not get a bios screen, so i am looking for suggestions or the type of hard case i can buy to use my hard drive. i bought a 2.5 from best buy and it didnt match.
This question was solved.

Hi:
You need to get a USB to SATA 2.5" HDD enclosure.
Did you remember to remove the hard drive connector from the disk?
The thing that looks like this? That is removable. You just have to yank on it.

Firefox start page but then nothing

I tried to upgrade to Firefox 3.6 and now all I get is the Firefox start up page and then nothing happens! I tried to lower the firewall and then reinstalling Firefox but still nothing but the start page!

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

My start button doesn't work in Windows Pro 8.1

I installed an Windows Pro 8 to 8.1 Pro x64 on a desktop computer. Both were clean installations, no other software was installed. With Window 8.1 Pro, the start button worked for a day after all the updates, then booted the computer. Now, if I try to right
click on the Start button with the mouse; nothing happens. Thinking it was a virus, I used Windows Defender to search to the for a virus and nothing found. No other Windows updates to fix the problem! To me it just another glitch in Windows!
I updated a laptop at the same time with Windows 8 to 8.1 X64, not the Pro version. The laptop was a OEM version of Windows 8. The laptop works fine with Windows 8.1 after upgrading it.

Hi,
Please try to copy WinX folder under C:\Users\Default\AppData\Local\Microsoft\Windows into C:\Users\[your user name]\AppData\Local\Microsoft\Windows.

Have an iMac 2008/09 on starting today I have a white screen, an apple icon and a constant rotating sun, nothing else. I've tried turning off and disconnecting and reconnecting the power lead with the same results. Any thoughts? Many thanks Matt

Have a 2008/9 iMac on starting up today I have only a white screen, apple icon and a continuous revolving sun. Have tried turning off and on and disconnecting and reconnecting the power with no affect - any thoughts or advice please. Thanks Matt

If your iMac came w/system DVDs, do the following:
Disconnect all devices from the computer then do the following:
Boot up from your DVD that originally came w/the iMac while holding down the "c" key.
Select the language you wish to use, and then choose "Disk Utility" from the menu bar.
Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the "repair disk" button in the right hand section of the window.
Once this process has been completed restart your computer and repair permissions directly from Disk Utility.
If Disk Utility is unable to complete the repair, you will need to use a stronger 3rd party utility like DiskWarrior, Techtool PRO (not Deluxe) or Drive Genius.

IMac DV green light on start button lights for a second then nothing!

Hi All,
My iMac DVSE 400 will not start up. When I unplug and replug power wire on back of iMac while in it is plugged into the wall socket..nothing happens, When I simply unplug from the wall sockect, the light in the on-off button turns green for a second or two...then nothing. Can you help me to diagnose and repair. Thanks.
iMac DV SE 400, 1 GB RAM, 128GB HD Mac OS X (10.4.3) Hope to get help!

I would suggest a PRAM reset. Immediately after pressing the power button, hold down the following keys; commandoption+PR. Let it chime three time, then release the keys.
Hope it helps,
Rick

When I am on a call and I come to hang up, the phone which when to my ear has a black screen, starts to light up then blacks out intermittently and in the brief moments it is lit up, the hang up button doesn't work unless I press home or lock buttons firs

When I am on a call and I come to hang up, the phone which when to my ear has a black screen, starts to light up so I can see and click the hang up button, but it then blacks out intermittently and in the brief moments it is lit up, the hang up button doesn't work unless I press the home or lock buttons first

Wow- thanks Jim! I removed the case and voila... it worked. Knock on wood that you solved my problem with such an incredibly simple solution. I'll find out where this proximity sensor is and make sure my case does not interfere with it.
Thanks so much.
