Mac won't stay on; fan keeps speeding up; then it goes to sleep every 3 min

What the heck is going on; its got a new logic board; its an older G5 PPC mac; and it keeps "going to sleep" on me; every 3 minutes.... is this the start of a hardware failure? In fact it even died on me during an OS installation....
Imac G5 PPC running 10.5 (trying to upgrade to 10.5.2)

It's unlikely that an OS upgrade will solve things, your problem is most probably a hardware, thermally related one. If the machine works for a little while after an overnight rest, the chances are very high that its heat related, and that in turn means hardware failure somewhere along the line. Ultimately, you will have to take it in and have it checked out. Depending on the model, you might qualify for one of Apple's Repair extension programs, however, they expire three years after the purchase date of the computer...

You're not the only one. See here:

The current fix is to turn off sleep mode or use an Ethernet cable.

- Try resetting the iPod:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
-Next try downloading/installing a free app. Others have said that works.

Why does my Apple TV disconnect from the internet while Im watching Netflix? If I reboot my Apple TV, it seems to stay connected longer, but it still disconnnects me from my Wifi every 10 mins or so. I am not connected thru the eathernet cable.

If you try by Ethernet you can verify if the issue is with your WiFi network or if your appletv is defect as most users do not suffer as you do

My upgrade for Snow Leopard for my Mac won't stay in disk.

I have the snow Leopard upgrade for my Mac OS X 10.5.8 like they told me I needed at Apple. But when I insert the disk it doesn't take it, it stays in for a few seconds then comes out. Is there anything I can do? Thank you.

Is Snow Leopard compatible with your iMac.? Check drive with Disk Utility. Does it read other disks? I think our experts maybe able to help. But will need more info on your iMac. Just my 2 cents.

My mac won't start up it keeps on chiming tried o

My mac won't start had a power cut and now all it does is chimes.
Tried to press options and c but still continues to chime

You could try the ol SMC reset.
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
http://support.apple.com/kb/HT3964
If it still does not work, Restart using your 10.5 Install DVD as the boot volume holding down C from chime sound to apple logo appearance, then after selecting your language from the menu bar go to Utilities > Disk Utilities, and run Repair Disk on your Mac's HDD. Afterwards, exit DU, exit Install, restart normally.

Mail app won't stay open and keeps crashing

I use iPhone 7.1. Every time I open my Mail app, it crashes. I don't know why.
I have maybe 700,000 unread emails, fourteen different email accounts (8 Gmails, 2 iClouds, 2 Gmx's, and 2 AOLs, all of which are linked together through my Mail app), over 16,000 photos, and 0 bytes of free space left on my phone.
I've had my phone since 23 May 2013.
I bought it off Amazon for $161.
How can I get my Mail app to work again? Whenever I open the Mail app, it stays open for about 60 seconds, then a black screen appears, and the Mail app crashes.

Hi don290022,
If you are having issues with your iPhone's Mail application becoming unresponsive, you may want to try some things to troubleshoot.
First, quit all running applications and test again -
Force an app to close in iOS
Next, I would try restarting and if needed resetting the iPhone -
Restart or reset your iPhone, iPad, or iPod touch
If the issue is still present, you may want to restore the iPhone as a new device -

Thanks for using Apple Support Communities.

Screen on my macbook 13" won't stay on. It just flashes once and goes off.

I've tried everything but nothing seems to work. I have a new Display inverter but the problem is not solved. What happens is that when i turn it on the display flashes once and then it goes black. When i hit the display's intensity bottoms it just flashes but won't stay on. Any suggestions? please! i can't find any apple technician around here as this is a very (very) small town. Help!

Mac won't stay running, no internet? PLEASE HELP!

Hi,
I have a 13" macbook pro.bought it refurbished and it was perfect- in january i brought it into a mac & pc repair shop since it was running a little slow and refused to burn CD's.
The problem they said was the operating system and the battery, so they reinstalled the operating system with an upgrade and the battery but now the laptop isnt running properly at all! ive never seen it so bad.
When it starts up it doesnt remember date & time, or network preferences. the battery condition says "replace" and when it does remember networks it wont connect as it says it doesnt have an IP address or has a self assigned IP address most of the time. and now wont stay powered on without the AC charger being plugged in even though its says its fully charged. The guarantee on the repair that i paid for isnt valid anymore.
how can i fix this? ive already reset the PRAM by holding down cmd,alt,P,R al at the same time as the computer starts up but hasn't helped.

My Mac won't stay connected to Internet after Leopard upgrade

Suddenly after upgrading to Leopard, both Safari and Mail report that Mac OS X isn't staying connected to the Internet. I'm using AirPort and a cable modem and it's always been reliable before. But now there seems to be something jumpy/fishy going on in the AirPort menu in Leopard's menu bar. The list of available networks changes very often and although my own network remains checked, Network Diagnostics shows that I am indeed getting disconnected often and for long lengths of time. But everytime I restart my Mac, my Internet connection is restored.
I had fully expected BETTER networking in Leopard, not WORSE.

So sorry, I have not checked back to Discussions til tonight. You have undoubtedly solved your problem. But just in case not...
http://docs.info.apple.com/article.html?artnum=107451 is where I learned about Soft and Hard Resetting of the Airport base stations. There is also a Factory reset that's not really on this page.
After I Hard set, I then went into Leopard's new interface for the AirPort Utility. Very straight forward to configure to set your station(s) up again. I've not had a problem since.
Again, soooooo sorry I didn't drop in sooner with this information.

My mac won't stay connected to the internet, and it has ethernet, it's not working.

My mac will not connect to the internet and i REALLY need it to! like NOW!!! this is a big problem because the internet is its primary use. this is realy bad. its using ethernet and i have tried everything i know of and im so confused and i need help... any help would be GREATLY apreceated! tysm!

When I connect the Mac directly to the modem it will connect. My other devices will not connect to the Mac when it's wired to the modem.
When the airport is connected to the modem all devices and the Mac will connect to it.
At some point, the airport will drop the internet connection, but the green ligjht on the airport stays lit. Diagnostics show it's not connected to the internet. iOS will connect to the network at that time, so will Mac, but none can acheive internet connection.
My ISP is xplornet as I am rural Canada. Spoke to them yesterday and thier end shows I have a connection, so they asked me to power cycle the airport and it connected no issues. They also said if it happens again, as in drops during the night, that it's likely my router that is the issue. My signal is great, the waether is sunny and clear and nothing is blocking my reciever on the roof...and I am sad becasue I lubs the internets.

HP P1102w - won't stay on, firmware keeps rebooting ?

Just picked up a new HP P1102w to finally replace my old trusty HP Laserjet 4p.
Unpacked printer, installed via USB on Windows XP, and printed test pages, and config/status pages.
Next, setup the WiFi config, and again printed test pages, and config/status pages.
However - the printer seems very flakey now - just sitting there...
The power/trouble lights alternating on/off, then all off -
then green on, and blue blinking, and then on solid.... until they all go off again - in 15 secs.
The printer is just sitting there -
repeating this firmware reboot, WiFi discovery, connect, - then all off again - firmware reboot -
Formatter - W4378e5
Firmware - 20130213
IO timeout = 120 secs
Jam recov = off
Sleep = 15 mins.
Auto Off = never

Hi ps56k,
I see that the printer keeps doing a firmware reboot.
I will be happy to help you.
Disconnect the USB cable if it is still connected.
I would do a power reset to see if that will resolve the issue.
With the printer still turned on, disconnect the power cable from the back of the printer.
Then disconnect the power cable from the wall outlet.
Wait 10 seconds and reconnect the power cable back to the wall outlet first, then the back of the printer and power it on again.
Make sure the printer is connected directly to a wall outlet. (don't use a power hub or a surge protector)
Try holding down the (X) Cancel button and the Power button at the same time.
Turn the printer on again to see if that will make a difference.
There is a newer firmware version: 2013-07-26 , Version20130703, 5.13M. But with the printer in this error state it probably won't update at this time. HP LaserJet Pro P1102w Printer Drivers.
Select your operating system, click next, click the link for firmware.
Restore the defaults on the printer by turning the printer off, hold down the x and wireless button.
Turn the printer back on and when the printer stops making noise release the two buttons.
See if that will take it out of initialization.
Here is a document on blinking lights.
Blinking Lights.
Please let me know the results.
