a friend recently gave me a g5 power mac that had some issues, and the failure was described as intermittant. The machine supposedly would work properly when booted and start freezing up after time, but if turned on the next day it would work properly for some time. I assumed it was an overheating issue, but apperently there is more to the picture. I have tried booting the machine quite a few times and the display always reads no signal. The machine sounds as if it were booting normally, but there is not output. At first I assumed it was my display cable, which was a DVI-D single link, however the DVI-D dual link cable leads to the same result. Is it nessicary to have a DVI-I cable? None of the error LEDs light up on the motherboard. After doing some hunting I haven't found anyone with the same issue, but I am wondering if I should assume the graphics card is dead. What steps do I need to take to isolate a graphics card failure in a power mac g5?

I have a G5 Power Mac dual 1.8 running 10.5.8. It powers a radio stations automation system. I have it set to power on after a power failure but for some reason it will not power on. I have to come t the station and reboot the system manually.

G4 733 D/A , 10.4.11. This morning there was a few second power failure according to my wife. Ther G4 shut down from the power failure. I didn't have "restart after power failure" selected in the Energy Saver prefs. I restarted the G4 when zi got home and after I was done with it, selected SLEEP from the menu. The G4 wouldn't respond to sleep. I logged out and tried SLEEP from another user acc't and from the login screen. I then went into the Energy Saver prefs, made sure everything was as I wanted ( 5 min display sleep, 10 min HD sleep, and "put disk to sleep whenever possible". I then rebooted and sleep still wouldn't function.

why i have to unplug the power cable from the back of my imac after every power failure at my home to get the imac to boot up. I've tried resetting the surge protecter and unplugging there. However, the only option is to unplug the cord from the back of the monitor/imac before it will boot up.Â

Have a white iMac (2Ghz Core Duo, 20" screen). It has started misbehaving slightly: it usually takes two or more tries to start from off, and has to have a hard restart if I've let it go to sleep on its own.If I have made it sleep myself, by pressing the power button, it always comes back, but it refuses to do so if I let it sleep on its own.My local reseller suggests that it may be a logic board fault: I'll have to pay ?70 to diagnose this and, if that's the case, the repair is uneconomic, meaning I've also wasted

I left my iMac on overnight last night to finish downloading some stuff. I woke up and all our clocks are flashing, so we must've had a blackout. Anyway, I went to check the progress of my downloads, and the iMac was off. I pushed the power button and nothing happened. No fan noise, HDD noise, nothing. I've been trying for almost two hours now and nothing is working.

I have a PowerMac G5 computer, running OSX Version 10.4.11. Up until yesterday, the computer performed flawlessly. Suddenly, yesterday, I get a message from Firefox (the browser I usually use), telling me that my Flash Player had been disabled because I did not have the most up-to-date version of Adobe Flash Player. When I investigated, I found out that the newest version was NOT compatible with my computer. So I tried reinstalling the most recent version of Adobe Flash Player that IS compatible and have had no success. When I go in to System Preferences and click on the Adobe Flash Player pane (under other), I get a message reading "could not load Adobe Flash Player." Someone out there must know how to handle this. I'm not in a position to purchase a new computer, and I desperately need Flash Player for some of the websites I use quite often.

My IMac crashes sometimes very suddenly, like in a power failure. It doesn't force quit or shut down, it just goes like somebody pulled the plug. It's usually possible to start it up again after 30minutes or an hour. The plug and lead seem to be fine. I tested it on another mac. The obvious suspicion would be overheating, but how can that be caused so suddenly (and how can I fix it)? It's an IMac Intel core duo, 20", 2 ghz, 2gb ram from 2006. I'm running Mac OS X (10.4.11) 2006.

I have a 2011 MacBook Pro 15 inch, and the Messages application has been installed and functioning well for the past year. A few hours ago, my MacBook ran out of battery and died on me. This caused a number of applications to function incorrectly, however, after a restart all of the applications EXCEPT Messages work correctly. Now whenever I start up the messages app and try to send a message to one of my contacts, their name appears in red and I receive a message that says "###-###-#### is not registered with iMessage." This occurs even though the contacts DO have iMessage and were working in the past. None of the contacts work currently.Â
I tried signing out of Messages, restarting my computer, restarting iMessage from my phone, deleting my plist file, but none of these seem to alleviate the issue.

While installing windows 7 via bootcamp tonight, I suffered a power failure a minute or two into installation. Upon reboot, I have only a black screen with flashing curse. I have attempted to reboot in safe mode, recovery mode and diagnostic mode, but I think the machine is not recognizing the keyboard.

I'm going to be setting up a dedicated server on a LAN soon. It's only going to be accessed by a handful of computers, all of which will be controlled by the client. Based on cost and complexity of other options, we've decided on a normal Mini, rather than a Mini Server or an Xserve.
The one feature that concerns us, which is included with the Xserve but not on either Mini, is the redundant power supply. We would like to avoid downtime in the event of a power supply failure. Are there any third party options to this?
(A battery backup with a limited run time would not be sufficient.)

Macbook Pro won't boot. Symptoms preceding failure included failure to open Firefox. When trying to cold boot I can get as far as the start-up sound, the Apple logo, and the spinning whieel (spins for a bit but not for very long) and then major failure. Not running Liom.

My Mac is OS X version 10.5.8
It powers down constantly and I was advised to check the box that restarts it automatically after power failure in order begin to ascertain what the problem is.
I cannot find the darned box to check!
I looked in the "energy saver" category where my computer tells me the box is, but there's no option anywhere to be seen.

I have a two-month old MacBook Pro at version 10.5.6 and have successfully done software updates several times. I have access to the internet over an Apple Airport via a cable modem.
Recently, I noticed that all my software updates fail with the following dialog:Software Update can�t connect to the update server. Make sure you�re connected to the Internet, then try again.The console reports the following:2/14/09 7:32:01 PM Software Update[1467] Error Domain=NSURLErrorDomain Code=-1004 UserInfo=0x8b0f80 "can�t connect to host" I searched on the net and found that others have had this problem on the net and followed their suggested advice (to no avail) to delete com.apple.softwareupdate plist in ~user/Library/Preferences/~user/Library/Preferences/ByHost/Library/Preferences/
I have also run Onyx & Yasu. But that did not help either.
Finally, we have another MacBook Pro - about 1.5 years old that is not having this problem.
Does anyone have any recommendations which would allow me to successfully perform updates?

I've recently attempted to install 2 sticks of 2GB RAM into my MacBook Pro, but unfortunately had jammed one stick in the lower RAM compartment (Apparently I forgot to enter it at 45�) and had a rough time getting it out.
The RAM stick is busted and had to replace it, but I'm quite sure the slot might suffered a bit.
What are the signs of RAM failure?

I have an older 15" G4 Powerbook (before the recalled Powerbooks with the RAM slot failures) that has recently been experiencing some speed issues. To my dismay, when I checked my 'About This Mac...' I no longer had 1GB of RAM, only a lowly 512 MB. Tonight I sat down and started swapping and removing my two sticks of RAM and as it turns out, something is up.
With a 512 stick in the lower slot, System Profiler tells me I have 512 MB of RAM and that the upper slot is empty. When I put the other stick in the upper slot (leaving the lower one in), System Profiler now says I have 512 MB of RAM and that the lower slot is empty. Does this look to be a (out of warranty) logic board failure? Is there anything else I can try to do? On a related note, when removing the screws from the RAM panel on the bottom of my PB, one screw fell into my Powerbook, never to be seen again. Is this going to cause any problems down the line?

The string of problems I've encountered started a few days ago. I normally let my imac go to sleep by itself but, on this occasion I told it to sleep via the apple menu. When I awoke the imac the screen was frozen. No mouse movement, no clock movement, nothing. At this point I turned the power off and back on again. It didn't get past the white screen (before the gray with apple logo). I then tried resetting the PRAM, booting in safe mode, and booting from my os disc. Nothing worked.
After several tens of tries it magically booted. It stayed active long enough for me to back up all my data (transferring at least 100GB), reformat the hdd, reinstall leapord, transfer data back, and use it until I let it sleep again.

I've been having intermittent connection problems with Comcast since February. Comcast can't seem to diagnose or solve the problem. Each time they get my connection back up, it goes down again a few days or weeks later.
I switched to Mac last August, with little difficulty. Yesterday, after my connection went down *again*, a "Mac expert" at Comcast told me that this happens with him a lot too. He said that it may be something I just have to live with, implying that it was a problem with Mac users.
Well, I don't have to just live with it, and I've decided to cancel my Comcast subscription if their last fix (a new router/modem) doesn't hold up. But I'm curious, has anyone here ever heard of such a thing? The excuse doesn't make sense to me, since I didn't have connection problems for the first six months I had my Mac. But in February, Comcast switched me to new (better!) servers. I wonder if that's the issue.

I have been a Mac convert for the last 18 months and am the proud owner of a Macbook 4.1 Dual Core, 2.4GHz using MAC OSX v 10.5.8. For no apparent reason, neither the Keyboard or the Touchpad respond and I end up using a Mighty Mouse and Wireless Keyboard which work perfectly ok. To make matters worse, this issue comes and go's without warning. I can go two months with everything ok, then suddenly it all stops working and then suddenly it's all ok again. It is almost as if there is a way of disabling these functions which I have inadvertently done. I have re-loaded the operating system which has not achieved anything.

Stupidly installed this: [URL] wanting better performance from my Nvidia 8600M GT 512Mb. Was asked to restart after install & wouldn't boot (only getting the grey then blue screen in 10.6.2) Am now unable to boot up in anything other than Safemode. While installing update is gives the option to revert, tried this in safe mode but it ends in a fail. If it can revert then somewhere is a backup of the original driver yeah? Where is it & can restore it manually/rename it as the original? Tried to use TimeMachine but won't boot for me in Safemode.

I have lost two Superdrives, and now this new one is acting up. I am getting the following error message after the verification has started:This disc can't be verified and might be unreliable. Try again using a new blank disc (error code 0x80020063). Could not open the data fork of "<unable to get file path>" (-43).

I used SuperDuper to create a mirror image of my SSD boot drive on one of the partitions on the external drive. Thinking it wise to actually check to see if the partition would boot, I used System Preferences to point to the new boot drive and restarted the ol' 2008 8x2.8 Mac Pro.
All seemed well with the startup from the new boot device. But when I tried to go to System Preferences on this system, the app failed without ever initializing a window.

Intel Mac Pro with Snow Leopard, 4 internal 2tb drives configured as a RAID 5 using the Apple RAID card. One of the four disks, always the same one (#4) occasionally drops out of the RAID and becomes a roaming disk instead of a spare. I get an error message from RAID utility telling me the array has failed, and when I look in the utility, the naughty disk isn't visible. Only disks 1 through 3. If I restart the machine the 4th disk appears but is listed as roaming. I can use the pull down menu to "Make Spare", thus reassigning disk 4 to the RAID set. It takes several days to re-establish itself as part of the RAID.
But then a few days later the same disk drops out of the RAID again. Is this a hardware problem with the RAID card? Or is there a software fix for this behavior?
