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.

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.

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?

IMac with bootcamp and parallel boots into windows 7 but won't boot into Mac OS lion?

Hi,
Thanks for your suggestion. Actually that was not the problem, because I had the Mcintosh drive set as my boot drive. The answer was that my Lion Os got somehow corrupted and I had to reinstalll Lion. This was all after I discussed the situation with the Apple Support people.

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.

Gaming in Bootcamp and video problems

I just got my new base model iMac yesterday and after I had it setup I installed a fresh copy of Windows 7 and then installed Everquest 2. When EQ2 launched though I ended up getting what is ultimately a DirectX error saying it couldn't run 3d effects. I ran dxdiag and it seemed none of the 3d functions are available.
I checked the video card in system properties and it is just appearing as a standard VGA card. I double checked with the Apple website and it is supposed to be ATI Radeon 5670 with 512mb of video ram.
I am sure Windows 7 isn't identifying the card correctly and that is the cause of my problems. Has anyone came across this problem and if so how can I fix it?
I haven't installed Steam as yet but when I do I have some Windows only games and don't want to be stopped by playing becuse of it.
Thanks

It sounds like the video drivers didn't install from when you put the Mac OS DVD in to transfer all the drivers to Window 7 that are required.
Have you tried "Windows Update" yet and see if it updates it?
Did EverQuest 2 possibly install old drivers?
Worst case scenario you might try reinstalling Windows and try again.
You might try this link?
http://support.apple.com/kb/TS3173
I'm not sure if this includes your version or not? This say's it pertains to the late '09 27"iMac and the mid '10 21" iMac but I don't know if this might work anyway? It "kinda sorta" refers to your problem. It involves starting over with the Windows 7 install though.
Hope this helps....

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.

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

How to Video: Debugging Windows Setup (Panther)

Here is a short(ish) 6 minute video on how to debug unattend.xml problems within Windows Setup.
Some Key Takeaways:
When running Windows Setup, press Shift+10 to get to cmd.exe
Look for logs in c:\windows\panther
A copy of the unattend.xml file will be in c:\windows\panther\unattend.xml
Double check each file to see if they have content (sometimes files listed as size Zero Bytes are actually not Zero!)
When asking for help on the MDT TechNet Forums, copy all the panther logs to a public site like OneDrive and share the link.

You should probably re-post in the Boot Camp forum.

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!

WiFi problems in Windows 7 using bootcamp

Hi
I have a "new" 2011 27" iMac and are sometimes forced to use Windows 7 with Bootcamp.
I installed the latest drivers using bootcamp assistant (and these seem to date back to 2011, so I guess that's what everybody else is using as well). The windows install is only two days old with all the recent updates installed.
When I start in windows I have two issues:
The major one is that the Wifi is there for around 20 seconds, then the screen flashes (like it's loading graphics drivers or something) and then the connection is lost. When I ask windows to repair it it figures out that WLAN autoconfig is not running and I ask for that to be restarted. Sometimes this will solve the problems, sometimes I have to repeat the "repair" a few times. Once it's working the connection seems stable until I restart.
The wifi works fine with Mountain lion and with all other devices we have. I tried the Apple hardware test and everything worked well.
The only clue I have is that after I installed windows I changed the location of the windows user account folder to the HDD instead of the smaller SSD. I did that by changing the default user folder destination to a MS-FAT formatted drive on the HDD, creating a new administrator account, logged into the new account and deleted the old account... But I just can't see why that should have anything to do with drivers and wifi.
The minor problem is that the sound always start out muted when I start windows. I unmute and problem solved (although annoying).
As I said there's absolutely no problems while I'm in Mountain lion, but there's a few windows only programs I need so...

Thanks for the suggestion Rudegar. I think I found the problem which was from a different source. I installed an external hard drive and initated Time Machine in my Mac OSX. While it worked fine for Time Machine when running Mac OSX, apparantly it was causing a problem with Bootcamp and Windows. When I realized this might be the problem, I sejected the drive in OSX and turned it's power off. I then shut down OSX and started up using Bootcamp and Windows as I has in the past with no problems.
Thanks ayway!

Problems Starting Windows 7 Using Bootcamp

I have a 2011 iMac which I have been running Windows 7 on for over a year through Bootcamp. No problems operating it for the past year. When I tried to go into Windows today through Bootcamp, I got to the screen where you selet your boot choice. When I select the Windows drive like normal, the screen tirns black (with very slight backlight) and just sits there doing nothing forever. I don't have a prompt of any kind and neither the mouse or keyboard seem to be operating.
Computer boots fine as a Mac and operates with no problem as a Mac. Tried several times to re-cycle. Shut down........restart while holding Option key......start using Windows drive.......all with the same results......a black screen......
Does anyone have any idea what is going on and what I can do to fix it?

27in iMac (late 2009) ATI 4850 drivers problem in Windows 7

This iMac is less than a month old. Windows 7 was working fine until a couple of days ago. While at the Windows 7 desktop the screen pixlated and froze. A tip bubble appeared in the notification bar that said the ATI driver quit but was recovered. The screen went black then restored itself. A moment later the whole thing occurred again. Is this a known issue? Is there a fix? Thanks for any help.

BANDING AND DRIVER CRASHING SOLVED:
I bought the following iMac on April 18, 2010 to run Windows 7 and Autodesk REVIT 2011.
27" iMac (Late 2009)
Intel Core i7, quad-core, 2.8GHz
8GB (4x2GB) memory
1TB Hard Drive
ATI Radeon HD 4850 512MB Display Adapter
Apple Magic Mouse
Apple Wireless Keyboard
Apple BootCamp with Windows 7 Ultimate
Installed OSX, downloaded and installed all updates.
Installed BootCamp 3.1
Installed Windows 7 Ultimate 64bit and had the problem of the black screen during install. This was solved with the fix from apple support (copy latest drivers to a flash drive and continue to install windows). This resulted in apple windows driver 8.681.0.0 and the 16 bit color with banding. Rolled back the driver to 8.661.0.0. The banding issue was solved, but then had intermittent crashing (reset of the driver) in Chrome and REVIT 2011. This driver caused yellow "dots", then lockup and generally would reset. Very disruptive to REVIT.
SOLUTION:
Went to ATI website and downloaded Catalyst 10.4, then manually installed ATI Mobility Radeon HD 4850 display driver version 8.723.0.0. This display driver has 32 bit color, does NOT exhibit the color banding and has not had screen flicker, driver resets, or crashing in any programs run so far. I use this computer only for Autodesk REVIT 2011. The ATI HD 4850 is not officially supported by Autodesk, but I am able to run REVIT 2011 with hardware acceleration and anti-aliasing with no problems. So far that has been only for one day, but was not able to go more than a few minutes with the previous drivers.
I have not run any speed benchmarks yet, but compared to my Windows 32 bit XP machine, the performance is much improved.
