Our 18 month old iMac G5 has recently stopped working properly. After a short period of use (5 - 20 minutes) the display morphs into what looks like a hazy bluish overlay of a series of vertical and horizontal lines/boxes. It also freezes. HELP! Any ideas?
If not you may want to join the others who don't have AppleCare and are not too happy.
Less sympathy found here:
If enough people complain Apple may extend the repair to more serial
numbers as has happened in the past. Macs are generally excellent
machines and well worth the money but problems can arise in
manufacturing considering the widespread sources computer companies
must use to compile their product.
Good luck, let us know what happens.

Re: Screen Changes and Comupter freezes
It may be possible that the power supply, display and or logicbpard may be having issues. Apple recommends resetting the pram and nvram. If issue persists reset SMU. YOur machine is 6 months outside of the original warranty, but if you purchased the 3 year extension plan, you may want to take action on it.

The iMac G5 and iMac G5 (Ambient Light Sensor) computers have a video out port located on the back of the computer, which will mirror video. Video mirroring means you can see the same image that is on the iMac G5's flat-panel display on an external monitor, television, or projector. Using the video out port, you can mirror video with a compatible VGA display using the Apple VGA Display Adapter. You can also use the video mirroring feature with a television or projector that has S-video or composite video connectors when you use the Apple Video Adapter. Both the Apple VGA Display Adapter (M8639G/A) and the Apple Video Adapter (M9109G/A) are available separately, and are needed if you want to use your iMac with a VGA monitor cable, S-video cable, or composite video cable. The video mirroring feature is "plug and play". Simply connect a VGA display, television, or projector to the appropriate adapter (see above), then connect the adapter to the video out port located on the back of the computer. When you connect the adapter to the computer, the screen may refresh momentarily as the computer prepares itself for the new video output. The computer tries to match the resolution of the built-in and external display. If there is no match, the computer changes both screen resolutions and may black out areas on the built-in display in order to match the capabilities of the external display. Important: To ensure that your iMac G5 automatically detects the external display or projector, be sure you plug the adapter into the external display or projector before you plug it into the iMac G5. You can switch resolutions and frequencies for both the iMac G5 flat-panel display and the external display, television, or projector using Displays preferences. Want to watch a DVD movie disc on a television that's connected to your iMac G5? Select a 720 x 480 NTSC (in the United States) or 720 x 576 PAL (in Europe and other regions) resolution in Displays preferences. Tip: Because of the display limitations of most televisions, the images displayed on a television screen are usually not as high quality as those on the built-in display or an external monitor.
If you can find you r way to the system preference panel... in the dock.. you can re adjust the screen display to the imac g5 setting. it should be listed when you look on the list of options.. You can also go to the finder and adjust the font size on the view menu... should be 12pt. K

Okay, you probably need a new power supply, this unit had many power supply and logic board problems. 300.00 is a lot for a power supply, 120.00 is the usual cost plus 50.00 labour, and that is canadian dollars, it should be much cheaper if you are in the U.S.
On the Dell, have look at your network connection setup.
( You don't say what OS you have on it )
There could be a box with a tick in it to automatically connect to nearby wireless networks.
Disabling this may help.
