24" iMac Video Problem on Window XP

I brought 2 units of 24” iMac last month and using boot camp to install windows xp. Both iMac are completed the installation of window xp and one of the iMac run normally but video problem found on second iMac. After running in window xp about 5 – 10 mins, the screen images distort suddenly. If computer restart again, the display will become normal for 5-10 mins and distort again. But the second computer runs normally in Mac OS. Please kindly help….

Are the driver installed, or installed properly?

ITunes / Quicktime Video Problems With Windows VISTA

I took up Windows Vista as soon as it was available and initially had no problems with iTunes. Then later, video clips (those purchased from iTunes and those I had converted myself) started stuttering / freezing and eventually crashing iTunes and finally I lost audio as well.
Ayyway to cut a long story short, I have uninstalled / re-installed Vista now about eight times for problems with installing drivers for USB devices (I've finally solved all these problems). After the last install the first program I installed was iTunes, tried video and it worked flawlessly. Then, each time I added a hardware device or program I would restart Vista and retry iTunes video.
The first item I added was a USB thumb drive (as I had on all previous occasions to take advantage of Vista's 'Ready Boost'). The thumb drive is a 'Sony 2GB micro vault tiny', and meets the transfer speed requirements for 'Ready Boost', as soon as I had set the drive up for 'Ready Boost' I started having the same problems with iTunes video and Quicktime.
Removed the thumb drive, restarted iTunes and had flawless video playback again. Have tried this over and over with the same result.
So my question is, has anyone else had video playback problems with iTunes / Vista and found similar problems. Trying to tie down whether this is a compatability problem with 'Ready Boost' or the thumb drive used. I have also tried a Sandisk Titanium 2GB with the same result.
I am not sure exactly how 'Ready Boost' works, I thought it added memory that was used to cache page files to the thumb drive instead of to the HDD making a faster seek /access time? Which should make things faster. Another article I read today was talking about 'Ready Boost' being an affordable extension to RAM, in this case I could understand the problem as I would think the access to a USB 2.0 thumbdrive would be slower than that to RAM.
Any help appreciated, but I guess my bottom line is anytime I want to watch video on iTunes, I just pull the USB thumb drive .
PC Pentium 4 Other OS Windows Vista Home Premium

I have the same stuttering video issues with iTunes and Vista. While I have used a thumb drive to transfer files (not Sony) I have not yet messed with Ready boost. I have seen several others complain about the video problem, perhaps they will chime in as well. Unfortunately, your solution doesn't work for me. I pretty much ignore iTunes, waiting for the next version (only god knows when it will be released).
I do have an external firewire drive connected, I'll disconnect later today and see if that has any affect.

IMac 24" Bootcamp scrambled video Problem in Windows Setup.

I just got a new iMac 24" today and was wondering if anyone else's iMacs are exhibiting display problems in boot camp (see picture links below and description) while in the windows setup screen or other LOW RESOLUTION screen modes.
http://disgruntleddesigner.com/imac.JPG
http://disgruntleddesigner.com/imac2.JPG
http://disgruntleddesigner.com/imac3.JPG
In low resolutions screen modes used by windows setup and the windows boot screen, the display is completely scrambled with moving pixel artifacts such as black vertical lines and misplaced color pixels all over the place.
The computer is a brand new 24" iMac 2.4 with all the latest OS updates. I called Apple's tech support and explained the situation and as soon as the tech rep heard the word bootcamp
he essentially turned his ears off. While I understand Apple doesn't support bootcamp I'm pretty sure this is a hardware/firmware issue and NOT a bootcamp thing.. but they suggest I write here instead of bothering them... so here's my plea for help.

Update.. I exchanged the computer for another at Best Buy and this one does NOT have this issue. I suspect it's a firmware or hardware thing after all.

Lenovo E540 video problems on Windows 8.1

Hi,
I've just recently bought a Lenovo ThinkPad Edge E540 with the following configuration:
- i7-4702MQ(2.2GHz)
- 4GB RAM
- 500GB 7200rpm HD
- 15.6in 1920x1080 LCD
- 2GB NVIDIA N14P-GV2
- CDRW/DVDRW
- Intel 802.11bgn wireless
- 1Gb Ethernet, UltraNav
- Secure Chip
- Fingerprint reader
- Camera
- 6c Li-Ion
- Dos license
The first thing i did was to install Windows 8.1, as it seems that it's the preffered OS for this laptop.
After this, i've installed all the drivers from the Lenovo Support site and all the programs that i normally use.
This is when everything went wrong.
In Photoshop CS6 i cannot zoom in and out, the image always stays the same. Only if i minimize and maximize Photoshop does the program refresh the image at the selected zoom level.
In Sketchup the same problem, if i try to rotate or pan the image, nothing happens. After minimize/maximize, the image is refreshed.
After a small research, i've discovered that i can change the prefferd video adapter from the Nvidia Control Panel.
Everything was set to Intel HD4600 so i changed all the mentioned programs to GeForce 740M.
This didn't solve the problem, but changed it. In Photoshop for example, this time the canvas doesn't appear at all.
So, a little research later and i found out that by disabling the hardware acceleration in each program, they started working.
This works on either of the video adapters, it doesn't matter which one is selected in the Nvidia Control Panel.
So i thought that i had it figured out, even though a new laptop isn't supposed to work like this, bypassing hardware acceleration in almot all programs
But the problem appeared in Microsoft Office:
In Microsoft Word, i can't change the text color.
In Microsoft Powerpoint, i can't change the background color.
Even if i disable the hardware acceleration, the problem is still there.
Finally i decides that maybe the operating system has an incompatibility with the drivers, so i formatted all and installed an older Windows 7 that i had.
Everything installed from scratch, drivers and programs.
This time all the programs worked (Photoshop CS5, Sketchup 8, Word and Powerpoint 2010) from the start, without disabling the hardware acceleration.
But the next day, when i wanted to use Powerpoint, the problem came back. The background color doesn't change, and in Word i can't change text color. Even if i disable the hardware acceleration.
So i'm back at the beginning.
I've honestly thought of returning the laptop, as it's the first one with which i've had all these endless problems.
Unfortunately, the store's 30-days back guarantee have passed, almost all of them trying to make it work as it should.
If anyone has any idea about this or has confronted any of these problems, please tell, i just don't know what else to do, the laptop is currently useless.
Thank you for yout patience to read all this.

I am also having this problem. Cannot click either button. Really hope someone can shed some light here.

21.5" iMac brightness problem under Windows 7

Even at lowest possible brightness under Windows 7,
this is much too bright for working in the evening/night.
I was using VistaShades under Vista, but now under Windows 7
VistaShades only darkens the background!
Does anyone know another program for reducing the brightness
which is Windows 7 compatible?
Thanks!
(BTW: I have the same problem using my 24" iMac under Windows 7
see http://discussions.apple.com/thread.jspa?threadID=2358779&tstart=0)

I has the same problem so i called a friend and all he did was go to navida's web site and download the beta drivers for gforce go 7600. make sure it is for windows 7. the ones on HP's website does not work and you can not use auto detect drivers when finding the driver.

JDeveloper 10g video problems with Windows Vista

Hi,
I'm using JDev 10g 10.1.3.3 over Windows Vista with Aero active. Since I started using Vista, I have always had problems with JDev. First, the fonts in the JDev panels would mess up and the scrolling would not work well. I made some changes in the way JDev uses the JDK, I don't remember exactly what I did, but I think I made the whole JDev environment to use a newer JDK, which is not engouraged/supported by Oracle. Since then, the scrolling problem was solved. But When I run my app, Aero stops working.
Is there a way to make JDev 10g work perfectly with Vista?
(No, I'm not willing to migrate to 11g, for several reasons, so I need to stick to 10g for now).
Thanks!
Brian

G3 iMac video problems

After some recent problems with my iMac shutting itself off with no warning (diagnosed from other posts on this site), I replaced the PAV board, but now when I try booting up, I just get a solid green screen after the usual start-up chime. Does anyone have any ideas what the problem could be? Is it possible that the new PAV board is bad, or that I didn't connect something correctly when installing it? The PAV board is new, not reconditioned (to the best of my knowledge).

I tried resetting the PRAM, but it had no effect.
When the power button is pressed, the usual start-up chime is heard, and the hard drive begins to spin up. After a few seconds, the green screen appears, the hard drive spins down, and nothing else happens.
I'm starting to wonder if something else failed - like the hard drive - along with the PAV board.

Windows 7 64 bit on iMac display problems and instability

I received my iMac 27" quad core with 8 gig ram & 2 x 1 TB hard drives last Friday. I'm using Boot Camp to run windows 7 64 bit on maximum 2560 x 1440 screen resolution.
I get intermittent but often display problems in windows 7. I get areas of the screen covered in little yellow dots or blue squares (never red artefacts.) This will happen at random areas of the screen, inside an open window, around borders of windows and so on. Most often the screen will go black and come back with a message in the bottom right corner of the screen saying 'Display driver has stopped responding and has recovered' with the sub message saying 'display driver ATI radeon family stopped....etc'. Sometimes I lose the screen wallpaper. Once I've had the system just shut down, once I've had Photoshop seize up and I had to do a cold reboot. Could this be an overheating problem or resolution too high problem or driver problem? Windows 7 tells me my drivers are up to date. I tried installing the drivers for the card from ATI's website which made no difference
The reason I bought a Mac is because it's the only effective way to code for the Mac family of OS's in XCode. The reason I didn't just attach a miniMac to my PC monitor was because there's rather a lot of advertising by Apple about the fact that you can use a Mac with a PC OS via Apple's own Boot Camp. Now I have a lot of Windows software (some of which is not available for the Mac or requires buying again) sitting on an unstable system. Any ideas would be much appreciated...

Sorry, that thread got moved for edit and as a user tip... which I didn't want and won't be doing....
Here is the post:
A tip and workaround for how to get ATI mobility/laptop drivers so that Windows no longer thinks the ATI is a desktop card:
http://discussions.apple.com/thread.jspa?messageID=11286987
Summary (my own edit steps):
1. Install Boot Camp 3.0 and upgrade to 3.1
2. Uninstall graphic drivers and run Driver Sweeper
http://www.guru3d.com/category/driversweeper/
instead of:
removing the crashing driver by going into windows 7 setup via its install cd and deleting the ati driver manaully
3. Install ATI Mobility (link)
4. Uninstall ATI (Programs control panel?) Device Manager (rollback; uninstall?)
5. Device Nanager: update driver and BROWSE BACK to 8.681 (the original apple driver that was causing freezes and purple artifacts) - navigate to /Apple/Drivers/ATI
(Apple uses) a 4850 card in the iMac, its modified a bit for apple. Enough that desktop drivers don't work, and modded-for-laptop desktop drivers don't work either.
Now the upshot of using modified drivers is that it FORCES the catalyst control panel to be installed, meaning you get a few more options to mess around with the card.
I couldn't use the original apple drive, it locks up, the newer one had banding, the newer radeon drivers direct form ATI wouldn't work until they were modded and then they cause black screens.
SO the solution, as obscure as it was, was to download ACTUAL mobility Radeon drivers - version 10.3 still, but made for laptops.
http://support.amd.com/us/gpudownload/Pages/index.aspx
THESE drivers I was able to install - and here is where things changed.
THIS driver changed they way windows saw the video card in device manager.
As I mentioned before, its NOT a desktop card, its a modified laptop card, but installing mac drivers makes windows THINK its a full desktop card, and running the original 8.681 driver crashed it.
Once installed 10.3 LAPTOP driver it now appeared in device manager as a MOBILITY card.
+These Steps "should" work:+
delete ATI driver manually
reinstall apple driver after that and see if that works,
otherwise try the steps above
(mod drivers, remove via windows recovery off setup disk, install laptop drivers, reinstall apple driver over it)

IMac Still Has Video Problems after Upgrade

I did the firmware and software upgrade to my iMac, which was supposed to fix the video problem, however the problem continues. I am using OS 10.4.11. My computer never "froze" however the screen went haywire. I would have to do a soft restart (if I could find the restart dropdown window) or I would have to do a hard restart. Now I can do a screen refresh to do a soft restart.
Is Apple aware the these Intel iMacs are a POS? I use it for 3D design and I can't work more than 10 minutes before my screen starts going wacko. I've used Macs since 1985 and this is the first POS Mac i've owned. I don't want to have to get another computer, I can't afford it.
Any others out there with the same problem? Any solutions?
Thanks

I like AppleCare, as you get three years of that unlimited phone support. I know many consider it just another extended warranty, but note it can be legitimately purchased at a discount.
Amazon, retail computer stores, also a number of sellers abound online and on eBay, and a price mentioned by someone else on here two years ago that hasn't changed since then - check out L. A. Computer Company, online - you might be surprised!
(I have no affiliation with them.)

I had to replace my iMac due to hard drive and Logicboard failure, so I want to reinstall Windows 7 on a Boot Camp partition. Will there be a problem reactivating Windows 7 Home Premium?

I had to replace my iMac due to HDD and Logicboard failure, so I want to reinstall Windows 7 on Boot Camp partition. Will there be a problem reactivating Windows 7 Home Premium?

Hi,
should be no problem.
Best case is you can activate online via Internet.
Worst case is you have to call Microsoft and explain that it is the same computer after a mainboard failure.

To map the drive on your computer click on Start - RUN - type "\\192.168.1.1" and click ok... When prompted for Username and Password type "admin" and click ok... Now you will be able to see the folder which you have shared on your router, right click on it and select "Map network drive" and click on finish.
Now it will map the drive on your computer and you should be able to transfer the file from your computer to the USB drive.

Apple aware of video problem in the new Intel iMacs

Macworld Daily News

Apple investigates Intel iMac Front Row problems
By Macworld staff
Apple has confirmed it is aware of, and investigating, reports of video problems in the new Intel iMacs.
Recent reports claimed that some users had experienced random horizontal lines and other video playback problems when playing video in Front Row.
"Apple is aware of this issue and is looking into it," the company said in an email to a web-based pressure group that has been gathering information on the problem. "If a customer has any technical issues, they should contact AppleCare."
The problem is allegedly software-based.

"Sure, I'd be more understanding had it been an issue that required a very special set of conditions to trigger"
Apparently it does as this issue is not affecting all users.
"As I was told, affected owners would not be proactively notified"
Where you you prefer them to use their limited resources, trying to figure out who MAY be affected and sending them some sort of detailed action plan, or spending the resources determining the cause of the issue and developing a solution that can be distributed to the ones who need it not only now, but those that may discover the issue next week?
I can understand that you are frustrated, and don't blame you for feeling that way, but this is an all new piece of technology and bugs are going to come up that were missed in testing. No company can afford to test at a 100% level. To do so would drive the costs so high as to make it impossible to sell the product, especially to the market the iMac is aimed at. Apple has a pretty darned good track record of resolving issues quickly when they appear. Until they do you only have a few choices. Use the workaround until the solution appears, waste time complaining about it, or sell the iMac and purchase a different product. That's really about all you can do!
It was good of you to spend your valuable time, and yes it is valuable, trying to help the engineers or service reps solve the issue. That they spent that much time with you should show their commitment to solving this issue.
Be patient, give them a chance, they have not had long to try and figure this out.

Could Bad RAM Cause Video Problems in 1st Gen 24" iMac

I have been having video problems with my 1st Gen 24" iMac over the past 6 months, but recently the machine wouldn't turn on at all. I left it at my local Apple Store to be diagnosed and they said that it was just a bad stick of RAM (not a big deal, its cheap these days). But what I forgot to ask them was, could that bad RAM be causing the video problems I've been having or is it the video card also?
Thanks!

Are you still having video problems since the ram was replaced? If the problem went away then it was the cause, it not then something else is.

Problems installing Windows 7 on new iMac?

I've heard from users on other forums that there are some problems installing Windows 7 on the new iMacs, mainly that the display goes blank partway through installation due to some kind of driver issue. Can anyone confirm this or elaborate? I've heard there is a workaround but it sounds a bit complicated and I'm wondering if I should just wait until Apple patches Boot Camp with full Win7 support.

I would wait until Apple updates Boot Camp to officially support Windows 7.

You could've backed up your iPad prior to the "forced" upgrade which, by the way, you could have cancelled. iTunes doesn't upgrade your iPad, automatically, on its own. You had to click the Upgrade button to initiate the upgrade. You didn't have to do anything with that button. You can just leave it be.
iOS 8 is garbage on iPad 2 and 3 and even though iTunes keeps giving me the Update button option, I continually choose to ignore it.
Ignoring the Upgrade/Update button doesn't affect the normal iTunes/iDevice syncing/backing up operations.
You could've just left that button alone.
When was the last time you backed up your iPad?
While there is no way way to revert to a previous iOS version once you upgrade your iDevices iOS, iTunes saves multiple backups of your iDevice and if you backed up your iPad previously to this latest activity, you should be able to restore your iPad from an older backup that should appear by date when you plug your iDevice into your Mac, was for iTunes to launch and sync your iPad, then cancel the backup in progress and use the Restore function in iTunes to restore your iDevice from another previous backup version date.
If your current version of iTunes doesn't recognize your iPad2 under iOS 8, you need to check the iTunes update feature, in iTunes or in OS X Software Update feature in OS X Preferences panel to see if there is a iTunes update available for OS X 10.6.8 Snow Leopard.
