IMac freezes with Halo UB game - after graphics firmware update

Hi
The graphics firmware update works good - the couple of things I found to freeze it work fine now.
But I have found one way to get the freeze and black screen plus the ASIC error in the system.log.
Open Halo UB 2.0.2 and set the video options to use 1920x1200. When I have it at 1344x840 or whatever, the game is fine.
But when I try to set Halo UB to 1920x1200, I get the freeze thing. Halo says it has to test the new video settings and says to hit escape if no dialog appears. Once I accept that, then the screen goes black and the freeze hits.
So I'm happy that everything's working good for all the other normal causes of the freeze. Hopefully Apple can now track down this issue.
Anyone else out there have Halo UB to try this out?
Maybe it's my Halo UB install. Mine was a fresh install this morning though.
good luck!
let me know...
thanks!

Freezes with Jedi Academy as well, freezes after iMac update, 10.5.1 install, Firmware Update (which i had to do with Pacifist)...
just Freezes and everything needs to be restarted, haven't tried the HALO thing yet, not sure if i want to push my luck...

  • Screen no longer works after Graphics Firmware Update

    I received my new IMAC 20 inch a couple of days ago. Worked like a charm. perfect.
    I received a request (software update) to update the Graphics firmware for the ATI 2600 processor.
    I performed the update, but I can no longer use the IMAC. The screen just stays black, no longer displays any information. I hear the hard disk working thru the startup process, but the screen just stays OFF.
    I zapped the PRAM, and restarted many times. No success.
    Please help. It worked so fine before this major trouble.

    The iMac Graphics Firmware Update 1.0 states:
    This update is for 20-inch and 24-inch aluminum iMac computers with the ATI Radeon HD 2600 PRO graphics processor, running Mac OS X 10.4.10 or later with iMac Software Update 1.2.1 for Tiger, or Mac OS X 10.5 with iMac Software Update 1.3 for Leopard.
    Perhaps you meant OS 10.5.1. The above update also states:
    Note: If you are running Mac OS X 10.5.1, iMac Software Update 1.3 is included.

  • IMac freezes with beachball

    Hi,
    I sometimes have a situation where, during use of Logic, all of a sudden my iMac freezes with the famous beach ball. Only the mouse pointer still moves when moving the mouse, and the harddisk temperature monitor util still shows changing temperatures every couple of second. I have the impression that the harddisk become unaccessable; it happened twice while bouncing a song. A couple of months ago I had this lockup situation a couple of times in 2 or 3 days, and since it hasn't happened until today. Weird! The only solution is to press the power button for 5 seconds (at least, couldn't get it to life any other way).
    Is this a known Logic issue???
    By the way, the HD temperature is around 55 degrees Celcius. Is this normal??
    Thanks, Jaap

    Yep, only with Logic so far...
    You might want to boot from the install DVD and run a verify check to see if there are any errors on the drive, also would be a good idea to repair permissions.
    Doubtful it's the drive temperature... it could even be the program that's monitoring the temperature causing the problem. Logic punishes almost every section of a computer, memory, processor, hard drive...etc. It's best to not have anything else running in the background if possible.
    How much memory do you have?
    Also... if you're working with a lot of audio tracks, the system drive in not your best choice for recording.
    OSX does a considerable amount of disk writes on it's own.

  • Question about imac graphics firmware updates

    My Imac model identifier is imac8,1; the machine is a 2.66 GHz Intel Core 2 Duo, with 2 GB 800 MHz DDR2 SDRAM.  I am running OS 10.6.7.  I have an ATI Radeon HD 2600 Pro graphics card.
    Firmware Update 1.0.1 is apparently installed, since my graphics ROM version is 113-82250L-259.
    Symptoms occurring within last 6 months or so:  Without notice, the screen goes black, though I can detect light “behind” (i.e., it doesn’t look powered off). The only remedy I’ve been able to get to work is to use the power button (or unplug) to turn the machine off. I don’t know whether the system has frozen or not.  I’ve looked at the console and system log, but I can’t tell from them what’s happening.
    I have reset the SMC and PRAM.  The computer passes the extended Apple Hardware Test.
    My question: is one or both of the imac graphics firmware updates 1.0.2 (September 10, 2009) or 2.0 (June8, 2011) appropriate for my machine?

    If there is an update to your particular graphics firmware, Software Update will let you know; if there is nothing showing there, it means there is no update available for your configuration. Do not simply download from the Apple website and install something that could cause havoc on your machine.
    I'm not sure what the problem might be, but it could be graphics card and/or logic board related. Since you've already done the SMC and PRAM resets, unless someone else has another idea, I'd suggest booking an appointment at your nearest Genius Bar for a free evaluation and diagnosis. If the problem is intermittent, take screen shots or video of it so you can show it to them.

  • TS3824 How can we install the iMac Graphics Firmware Update if the screen is white and I can't get to the Apple menu?

    How can I install the iMac Graphics Firmware Update 2.0, if the screen is white and I can't get to the Apple menu?  My computer has 5 vertical purple lines against white screen at startup before the Apple logo appears and the spinning gear...then everything disappears and the screen hangs on the white screen.  I have tried unplugging and removing all my peripherals and the COMMAND, OPTION, P & R set of keys and still nothing.  I have tried COMMAND C to start up from cd and it only tells me to turn off the computer and turn it back on.  I found information on Apple's Support pages regarding the iMac Graphics Firmware Update but I am unable to download and install if I can't get to the Apple menu.  Can anyone help?

    You may have hardware problem, I think a visit to your local Apple Store or AASP is in order.

  • I have been having problems with my speaker. After the recent update I am unable to listen to movies or music using my speaker. The volume bar is completely missing. If I plug a headset into the port, the volume bar reappears.

    I have been having problems with my speaker. After the recent update I am unable to listen to movies, music or apps using my speaker. The volume bar is completely missing. If I plug a headset into the port, the volume bar reappears and then disappears after the headset is removed. This is quite annoying. My child's Apps that he likes to play will not even make a sound. HELP!!!

    Do a reset (Hold Sleep/Wake and Home buttons about 10 secs or more till Apple logo appears, ignore the Slide to Power Off that appears)
    Note: You will not lose any data.

  • How to install Graphics Firmware Update 1.0 in Lion?

    I'm trying to install Windows 7 on a 27" iMac with a NVidia 7600GT graphics card.  Knowledgebase article HT3986 says that Graphics Firmware Update 1.0 must be installed first. I downloaded the firmware update  but on running it says the Mac OS X 10.6 is required  but I've already upgraded to Lion.
    I was able to install Windows 7 but I have to disable the graphics card for it to boot and use it in VGA mode.
    How can I install the firmware update?

    I used BC 4.0. I don't remember installing the firmware update and thought it likely that I would skip it as I didn't intend to install Windows.
    Here's the system profile information:
    NVIDIA GeForce 7600 GT:
      Chipset Model:          NVIDIA GeForce 7600 GT
      Type:          GPU
      Bus:          PCIe
      PCIe Lane Width:          x16
      VRAM (Total):          256 MB
      Vendor:          NVIDIA (0x10de)
      Device ID:          0x0391
      Revision ID:          0x00a1
      ROM Revision:          3022
    I can't find info on what to look for on this iMac to know if it's been updated.

  • Wlan error after a firmware update

    Ok there seem to be many posts about this issue but i cannot find anything that seems to work for me.
    I not to recently updated my N95 8Gb firmware to 20.0.16 and found that I was having errors with WPA on WLan, previously I had no such problem and the issue only occured after the firmware update.
    to add some more info I am on a network with a linksys wrt300n
    I have tried wep it works but dont want to compromise security.
    All computers on the network are using wireless g and the key is definitely correct when entered
    any help would be most appreciated

    I don't have N95, but if the firmware is updated to latest version the wpa most likely wpa2. Having wpa in place of wep gives only very little added security for a determined hacker! It will only takes 30min to an hour to crack that. Security like that deter only the free net riders. Try if there is upgrade for your modem/router, its usualy the case. For home network wep or wpa sufficed.
    Knowledge not shared is knowledge wasted!
    If you find it helpfull, it's not hard to click the STAR..

  • Frozen at the "Graphics Firmware Update 1.0" dialog

    I installed the Nov 15 graphics update on my iMac 24", but when I clicked the "update" button on the "Graphics Firmware Update 1.0" dialog, it just froze.
    The dialog has not showm any progress since I clicked the "update button". It has just been sitting there for about 30 minutes. I can move the mouse, but nothing I click on responds.
    The bad thing is that this dialog box warns you not to touch anything or else the computer will not boot.
    Has anyone else had this problem?

    Well, I gave up and rebooted. It did reboot, and when I logged in, I got a dialog box saying the graphics was updated to version 1.0.
    However, when I rebooted using bootcamp, Windows still shows the ATI Mobility HD 2600XT driver as being version 8.390.0.0 6/14/2007. That's what it was before installing the update.
    I thought updating the Leopard would update the bootcamp partition as well. Is this supposed to be done separately? Or maybe when the updated froze, it didn't update the Windows side. In which case I would have to uninstall/reinstall the update.
    I am guessing here. I have no idea what to do. Does anyone know the answer?

  • Bluetooth doesn't work after E90 firmware update!

    Nokia staff - help needed!
    Bluetooth has stopped working after E90 firmware update.
    The following on-screen message is shown: "Unable to perform Bluetooth operation!"
    P.S. Reinstalling firmware via Nokia software update doesn't help at all. If connectivity problem still can be solved with USB cable, the worst tning is that I can't use my phone's BT handsfree when driving.

    Hi hanzzi
    No information as to what device you are using, but try deleting E:\CITIES + .qf file from memory card then restart OVI Maps application to re-define folder structure required to download regional mapping using OVI Suite.
    Happy to have helped forum in a small way with a Support Ratio = 37.0

  • After a firmware update to airport express should I unplug the unit then plug it back in? (bascially reboot it)

    After a firmware update to airport express should I unplug the unit wait a bit and plug it back in?  (basically a reboot)

    I updated the firmware on the 2nd of this month.  Everything was fine.  About a week later internet speed began to be slow.  I rebooted the modem and the speed was okay for awhile, then slow again. I'm wondering if it's the airport express.  It didn't tell me to reboot at the end of the installation.

  • Incompatible after the firmware update

    I had missing the dictionary (including the icon on the screen) and chinese language currently stored in my nokia 6680 after the firmware update. what is the problems?

    Yes I m using one of the default themes.
    I have even done the re-installation of the same firmware version again, it did not work.
    Each time I flash the firmware, installed applications become unworkable although the icons still remained in the menu. IT is always a great hassle to have to re-install all applications over again.
    tsk.
