My Quicksilver G4 boots up and after a few minutes working shuts down

My older Quicksilver G4 boots up in a completely normal way and then after a few or more minutes working inadvertedly shuts down.
I checked out if in sleep or shut down pref's something was changed?
Is it possible the motherboard battery that fails?

Hello Ollie,
Have you blown the dust out lately?
Especially the Video card, CPUs, RAM, & PSU.

Flashing file folder with a question mark when starting my macbook after a few minutes it shuts down, any ideas??

When turned on our Macbook flashes a folder with a question mark in the center screen, then it shuts down after a few minutes. Doea anyone have any ideas how to boot the computer back up?
Cheers

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Just press the Return key on yourkeyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left handlist. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

My Mac Mini starts to boot up then after a few minutes turns off. Please help.

My Mac Mini starts to boot up then after a few minutes turns off. Please help.

seen this happen many times, usually always due to corrupt memory.......could be a power module in the Mini, but unlikely. hold down command R on startup, see if you can get into safe mode or ANY SCREEN ...If under warr. call mac for a service check, ....BUT if you have spare memory around that is compatable, try that first, process of elimination diagnostics.

After a few minutes, the page down won't work without clicking the mouse pointer on the page I am reading to activate page down again. Is there a way to go back to page down working every time without having to click the page first?

Question
After a few minutes, the page down won't work without clicking the mouse pointer on the page I am reading to activate page down again. Is there a way to go back to page down working every time without having to click the page first?

Today, two other users reported issues with the back-forward history list dropping down if they hovered the mouse pointer over the back or forward button -- without clicking -- and then moved the pointer downwards. One user was on a touchpad, I don't know about the other user. Are you experiencing anything like that?

When i open my computer I get the white screen with apple symbol and there are vertical lines all over the screen with green pixels and after a few minutes the screen gets grey and I get message to restart my computer what happens

3 years ago I bought an IMac Desktop that I am using for a lot of things but the most important for dvd montage in Imovies and Idvd.
Now today when I opened my computer I get as usual the white screen with the Apple symbol but there were all over the screen vertical lines with green pixels and after a while the screen gets grey and I get message to restart my computer using the power button or the restart button and when I do so each time the same is happening somebody can tell me what is happening and what caused this. This computer is my work and now I have no income anymore.
On the Apple support site they are asking to enter the serial number and when I do so I get message it is wrong but it is the only one I have and I buy this computer in Cairo Egypt. I am living in Hurghada in Egypt for the moment. When I call the technical support of the shop where I buy it they are telling me that it is the hard disk or ram and that I probably lost everything on it and they are asking a big amount to repair.
Can somebody advise me on this matter. Thanks in advance

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.

Apps shut down after a few seconds, apps shut down after a few seconds

Hi. I have an iPhone 4S running iOS5.1.1. Since the update, all of my apps, including messeges and email, close after a few seconds. I can't send messages, or use any of the apps. I have reformatted the device several times, and also done a fresh install as a new user. I still have the same problem. Can anyone give me suggestions?

Thanks. Tried this and still not working. I can't even send a lengthy sms or email, as EVERY app shuts down after a few seconds. Sometimes it even fails to launch. The battery life is less than 4 hours, even after turning off 3G, wi-fi, bluetooth and cellular data.
It must be a hardware problem, as the phone gets extremely hot as well.
Apple are far from helpful. Their customer service is dreadful, if you live outside of the States. No telephone or email support. Time to flush the phone and buy a Samsung Galaxy 3.

I restarted my macbookpro but it doesn't start again. It starts to run and a grey screen appears bus after a few seconds it shuts down. Please help. I can't find anything online

Help me please just a grey screen with the apple logo appears and it looks like its going to start up but doesnt

See if you can boot into safe mode by holding down the shift key immediately after pressing the start button. Keep holding the shift key till a loading progress bar appears on the lower part of the screen. It will take a lot longer than normal to start this way. If you have Lion 10.7 installed you can try holding command-R keys to get intto recovery mode and run disk utility.

HT1212 I have done the steps under the alternatively and it will does not restore and after a few minutes goes back to the page that the ipod is disabled page. Now how can I get past this?

Need help resetting ipod touch? I have followed all the directions and still it goes back to ipod is disabled connect to iTunes.

Try disabling the computer's antivirus and firewall.
- Next try the manual install method of:
iDevice Troubleshooting 101 :: iPhone, iPad, iPod touch
Place the iPod in recovery mode after the firmware download is complete and then restore using the instructions in the article. Sometimes recovery mode timeouts and returns to disabled before the firmware download is complete.
- Then try on another computer

When I try to transfer photos from my iphone to my ipad the transfer stops after a few photos and after a few minutes i get a box saying transfer failed (in dutch)

I tried re-installing iphoto and changing the settings for adding location to the photo.
I want to transfer the photos from my iphone 4s to the ipad (the new) via wifi uding iphoto.

You should not do anything else without testing import from your memory card (or cards) when using a card reader and not connecting to the camera. Connecting to the camera should be avoided when possible, anyway. See:

Xcode 4.2 crash after a few minutes working on Build Settings

Working with the Build Settings screen the editor area turns gray in a 75% (only one square visible) and the only solution is to restart the mac mini. It seems like running out of video memory.
Using XCode 4.2
Mac OS x 10.7
Lion
Thanks

How to reproduce the problem:
In Build Settings switch between Project and Targets several times.
Some times resizing the screen the problem is solved. Other the Mac hangs.
May be it's a refresh problem... Is there any patch?

Shutdown restarts after a few minutes and sleep shuts computer down.

When I shutdown my computer, the shutdown process starts, computer goes into "logging off" and continues for a few minutes before restarting automatically. When I go into "sleep mode" , computer appears to go into the proper mode, but a few minutes later, shuts down. When I log on again, Windows advises that I had an abnormal shutdown. Sleep and shutdown appear to have reversed for some reason.

Hello hankaree,
Knowing what model computer you are using and what operating system you have will allow me to provide you with exact instructions if needed, however try disabling all non Microsoft applications to startup on the computer and put the computer in a clean boot state.
1. Click on start
2. Type in the search field or click on the run application depending on your OS
3. Type MSCONFIG
4. When the mosconfig window comes up click on the startup tab
5. Disable all
6. Reboot
7. Test
If the system behaves as normal then we can start enabling things to see if we can find what is causing the issues. If the problem persists we can start trying to looking at other solutions.

My MacAir purchased Sept 2011 gets exceptionally hot after charging for 10 minutes when the fan comes on. This also happens if I'm listening to music or watching something on YouTube after a few minutes. The machine gets hot and the fan comes on.

My Mac Air purchased in Sept 2011 gets exceptionally hot after only 10 minutes of charging with the fan coming on. This also happens if I'm listening to music, watching a video, or doing an online crossword puzzle. When I shut it down the fan continues for a few minutes before shutting down. I took it in to the Genius Bar and they claimed the heat was within specifications.. I've owned several Macs and Mac iBooks in the past and this has never happened before.. Has anyone else had this same problem or have heard of it?

Hi...
It should not get that hot under 'normal' use.
First try a SMC reset.
Also note that it's a known issue that when attaching the magsafe connector and then within a few seconds opening the lid or in reverse, it can heat up for no aparent reason. Closing and reopening the lid should solve that.
A workaround for this is to wait ca. 15-30 sec. after opening the lid, before connecting the magsafe.

After a few minutes the Touch Screen doesnt work properly anymore. (sporadic Touchscreen errors)

Hi,i use my phone like i always do and after a few minutes the Touchscreen starts making errors and it quickly gets worse till a point where i cant use it anymore.After shutting down and leaving it for a while, the described case above starts over. And thats the only thing which seems to help. I searched through this forum, but to be honest i didnt read all, there are too many post about Xperia Z1 touchscreen problems.Some speculated what the cause of this problem might be, and they were not even sure wether it is a software or hardware issue!?Software repair with PC Companion didnt help.I reviewed Touchscreen settings, didnt help.
Most important to me the question, is this problem covert by sony warranty? Thank you

Hi, This in reference to the complaint registered before. I have been facing touch issues on my Sony Xperia Z1 bought in Feb 2015 from Spice Hotspot. I had given it for repair at Sony service center in July 2015, wherein it was delivered to me after 15 days stating that hardware has been replaced and the issue is no longer there. But I am still having touch issues and they are even worse then before after the repair. I am unable to type even for 5 seconds continuously the screen goes crazy and starts typing, selecting on its own. I want my handset replaced or return my money back. This phone has become a pain rather than convenience. If you do not act on it asap I am going to consumer court and will file a complaint against you. Thanks,(**bleep** annoyed Customer)
