Kernel Panic 10.6.2 Unsolved Problem

Question

I have been up and down search engines trying to figure out how to fix this problem I recently encountered on my iMac.
The problem happend as followed:
I have a 32gb partition on windows vista on my imacs hard drive. Windows wanted me to do an update as usual, and i did. When it was in the third and final stage of configuring the update, the computer froze and I had to restart the computer.
Once i turned on the mac, there was scattered "stuck" pixels all over the screen, some were flashing blue.
I tried to enter windows through the option key at start up but it just brings me to a black screen.
When i try to boot in OSX it loads for an abnormal amount of time then brings me to the multilingual error message. I restarted several times reaching the same error, with the same "stuck" pixels.
I retested the PRAM, heard the two chimes.
THis time, the "stuck" pixels were in a new pattern, vertical lines down the screen, about 8 across every 2 inches.
After resetting the PRAM it still brings me to the black screen in vista and kernel panic message in OSX.
Then...
I entered single user mode, and it found some errors using /sbin/fsck -fy
I ran the command a couple of times to ensure all errors were fixed and the "volume appears to be ok" appeared consistently.
I then used "shutdown -h now" and turned the mac back on.
The pixels were still on the screen and still brought me to the kernel panic screen, as well as the black screen in vista.
I gave up and left my imac off for about 5 hours.
I came back with new hope to try and fix the computer.
I removed all first party ram, two 1 gb sticks, then reinserted.
I turned on the mac and everything was fine.
For some reason the fans in the imac were on full power blowing really fast.
There was no more stuck pixels on the screen and it booted, very slowly, to OSX.
As soon as I entered I used the disk util and repaired permissions. There seemed to be many errors in the flash plugin folder. maybe about 30 of them.
I restarted the imac, and everything was fine, everything was back to normal speed.
Once the imac went into screen saver mode for about 15 min, the screen froze and the flurry screen saver looked distorted. I restarted the imac.
Once i restarted the imac the same "stuck pixels" were back.
I tried using all previous methods, all volumes appear ok in single user mode but I continue to receive the kernel panic message along with the pixels.
I can not start from the snow leopard dvd, because i get the kernel message.
I can not boot into safe mode, because of the kernel message.
I can not use a live linux CD because it takes me to a black screen.
Although I did notice one thing.
Once I use the /sbin/fsck -fy command follwed by the exit command, i receive a string of messages, checking the normal functions.
All appear ok but there is a message mentioning the NTFS partition log check not being clear, then it says unable to mount volume cant (read/write)
I am assuming the vista update somehow damaged something but i am unsure because I was able to boot normally into OSX twice after I received the symptoms the first time.
Does anyone have any idea on how to fix this?
THank you for your time reading this very long post

Answer 1

EXACTLY!
The same thing happened to me while in vista, in bootcamp.
I had just bought left for dead 2 and the game would suddenly freeze and loop audio constantly
I restarted the imac and it was fine.
I tried playing the game and the same thing happened.
So i figured it was some new windows update i didnt have.
So when vista was in the 3rd stage of configuring the update, the computer froze once more and once i restarted i began getting kernel panic issues.
When i was able to boot back into windows, after the kernel panic issues.
there were about 5 or 8 Big block of pixels, about 64x64, dancing around the screen flashing different colors. I brought me to the windows start up error screen where you choose to start in safe mode or not.
I selected start windows normally and then i received a blue screen of death...on a mac.
After that I have no longer been able to boot off of dvds, of any partitions.
I know it has to be issues with the graphics card, i dont believe its fried but maybe corrupt drivers. Is there some way to reinstall those drivers perhaps?
I called 2 local expert mac technicians and they are pointing to video card issues.
Which sounds true because the mac performs fine in VGA mode(single user mode, and apple hardware diagnostic tests)
The mac begins to boot OSX but i believe once it tries to load the video drivers it goes into a kernel panic.
Maybe we can solve this some how.
I will try to post the kernel panic logs.
