    Yeah, since I deleted ATIradeonX1000 life has been better, just figuring out the pixel situation now.  I am going to try your recipe when I get home this evening and see if that will cure it:)

     

    *I have a qurestion based on being new to mac computers.  I am running 10.4.11 currently and want to upgrade...what (in your opinion) is the best upgrade I could make knowing this specific machine?  I know I can't do Mountain Lion for sure, but didn't know how far I should or could go up.   And do I need to go to 10.5, before going to 10.6...etc?

     

    Ian, you have been a HUGE help and I will report back with what happens after I try your method:)

     

    Thanks again!

    Mine was A1150 15". I understand your A1151 is a 17" with a faster CPU but otherwise much the same. Which OS you use depends on what applications you need to run. I also have an old PPC iBook that will run Classic on 10.4.11. 10.5.8 is good because old universal binary applications run fine. On a budget, you don't want new applications when the old ones do enough and work fine. 10.6.x is a bother for old applications because Rosetta isn't 100% compatible. I am still running 10.6.8 on my new machine early 2011 and had to spend lots upgrading commercial Adobe apps.

    That my friend is a driver err. your options are to A: to delete the Windows partition and do a clean install again and download the drivers apple has listed on tehir website for macs running bootcamp OR B: if you really want to just run windows on your Mac and not OSX then do this (assuming your running mountain lion) Make/Obtain a bootable USB with mountin lion (after you alread made the windows partition and installed it and dowloaded the bootcamp drivers and use the bootable thumbdrive loading into the installer then instead of actually installing mountain lion your gonna click the disk utility option then erase the OSX partition on the hardrive and Viola you have  a windows computer in mac cloathing

    I have the ati problem also,

     

    Few weeks ago crash waking from sleep, then 11 days ago system crash with lots of lines on the screen.   Could not boot normal (it would crash) but I could boot into safe mode and have a normal screen.  Time machine would not backup because Spotlight was not indexing.

     

    I looked through the console:

     

    MacBook-Pro-15 loginwindow[37]:

         O3REQUIRE FAILED: ret == 0

            - file: /SourceCache/BezelServices/BezelServices-232.3/Utilities/Utilities.c

            - line: 91

     

    At the log in window is where it would hang in a normal boot, safe mode I am able to login and use a few apps (I found this discussion and others in safari

     

    One of them mentioned removing the ati files from the extension folder. Tried that, it worked (using a efi driver) I have only 5 MB of video ram instead of 256 VRAM

     

    Late 2006 MacBook Pro 2.33 ghz    Had 10.4 no big problems, 10.6.x has no battery bundle for the model (still does not, bug report filed). I am on 10.7.5    The ati x1600 files have a date in 2011

     

    So it seems the issue is part hardware (I had almost no thermal paste on the gpu and others) and some file corruption (some things were in a crash loop) seems some ati files are bad (did 10.7.5 combo updater no luck) it seems some files got corrupted in the hang.  

     

    So it seems Macs with ati x1600 has had this issue since around 2008

     

    I now need to figure out how to get the lines off and what software to fix, and what hardware

    Got a temp fix, friend helped me to redo the thermal paste, there was about none left on the gpu etc, it looked like crushed crackers, that help with the temp a bit, it went down a few ºs , right now if the gpu discrete thermal diode gets above 140º f then I get the lines, and have to restart the mac

     

     

    (for me I could not boot to the recoevery mode) I used my 10.6 dvd to do a repair disk the disk, (I then got disk utlity to mount the recovery partion, and repair it) so I could then I got in to recovery mode to try a reinstall of 10.7 (recovery would not download the installer, so I went to normal redownload the installer from App Store, then went back to recovery mode and then told it to reinstall and it downlaoded the installer) (not sure about how to reinstall 10.5 or 10.6 for reinstall and keeping settings and apps)  it seemed the gpu crash did break the grafics card drivers, as I have the Ati x1600 & others again (have 256 vram) and have no lines on the screen (if I keep the system cool)  I have the left & right fans set to 4000rpm (via istat menus, can be done with others too)

     

    Have not gotten a efi diagnostic test on the gpu and logic baord yet, has anyone else gotten those tested to see if they are failing?

     

     

    So it seems part of the issue is bad thermal paste or paste that is gone from the logic board, which then the heat does not get out right and stays on the logic board and other things, posiblely cauing heat damage to parts  (http://support.apple.com/kb/ts2377 "These computers were manufactured between approximately May 2007 and September 2008"  Mine was made in March 2007 not long before the nvida ones had issues, did these ATI we have have a similar issue when they were made?)

    SOLUTION THAT WORKED FOR ME WITH ATI X1000 kext enabled, macbook 1,1 model a1150 - 2 copper coins fixes it !!!!!!!! 90%

     

    OK update for all you guys still trying to work with older macbook pros struggling with this problem, I resolved it on my macbook pro A1150 properly with no disablement of the ATI x1000 kext, everything work fully, for my glitches it turn out that as per usual overheated SMC BGA chips are the problem, the 4 vram chips mounted on the opposite side of the logic board appear to not making full contact causing the display glitches, simple solution which just worked for me, playing youtube videos for 30 mins no glitches on boot no issues unless full screen 720p video for  more than an hour, you will need

     

    2 x 2 pence peices or equivalent dimension copper coins to 2p UK currency or theyre equivalent material and dimensions in copper foreign currency.

     

    2 x double side sticky sponge pads smaller than the coins but sufficient to hold them I used sellotape sticky pads 19mm x 19mm with 2p coins.

     

    1: remove upper case

     

    2: locate the the vram chips on opposite side to ATI GPU, top side of logic baord as visible when opening upper case, the chips are in pairs 2 across near vent and 2 down nearby them, on reverse ie visible side of logic board to where the ati chip is solderd onto the logic board, (ie no need to remove logic board they are on the visible side) place 1 two pence peice overlapping each pair of vram chips

     

    3: place sticky pad on top of each copper coin

    4: Then carefully align top case and place back onto main case without disturbing the position of coins, this should stick the coins via the double sided sticky pads onto the back of the keyboard on the upper case so when you lift up upper case the coins come with it stuck to the back of keyboard,

     

    5: Reassemble as per usual making sure to do up all screws nice and tight especially the four long philips case screws on the rear of the back case, you may have to squeeze the the two halfs of the case together a bit especially at the location on the case where the screw is closest to the copper coins, once you have all screws in tight, with the extra pressure of the copper coin heatsinks you are applying to the vram chips, they will now make better contact to the logic board, and therefore now work correctly!, I know this sounds ridiculous but it actually worked completely for me, I now have my x1600 working properly ! with ATI X1000 kext functioning with no glitches, Its also worth noting I have copper shimmed the chips on the reverse and redone thermal paste prior to this but it did not not resolve the problem of glitching until I applied pressure to the vram chips in this manner.

     

    The problem was only resolved when I applied the two pence peices to the vram chips, which I beleive is the cause all along, Im guessing this means that perhaps a bake of the motherboard might resolve the issue with the vram smc bga chips, as mere pressure onto these chips seems to resolve it!

     

    experiment at your own lesiure report back results, but im personally very chuffed with this result.

     

    I hope this helps someone ?

     

     

    perhaps I spoke too soon worked for 60 mins worth of video watching on vimeo and youtube, QE CI working as getting droplet effects working in dashbaord when placing widgets etc - then I had a hang in safari - no glitching screen at all though and none after reboot either ? justa straight hang, gonna try a fresh reinstall as maybe I have allot of stuff that was corrupted from the time i was running with the glitching video, and as ian cheong instructions states maybe some files need clearing out as maybe corrupted from previous times ? I also note that my repair though fixing also puts a low profile bulge in the keyboard, as basically my method is to sandwich the chips tighter onto the logic board and the copper coins/shims take up space, just rebooted conducting testing now tightening the screws a little further. will report back how stable fix is temps are very low cpu core on video browser use 38degc did use arctic cooling mx2 thermal paste properly and thinly applied.

     

     

    Ok update I cleared out corrupt preferences as per ian cheong instructions did an smc and pram reset, did a gigs worth of OS updates to 10.6.8 for 45 minutes no screen glitches of any kind, it certainly seems as if pressure on the vram chips has massively improved the situation by at least 90% its kind of night and day compared to before with no pressure on the vram chips, ie until I get the hang there is literally no screen corruption of any kind ? but I am not at all 100% stable. Pity so many hot surface mount BGA chip packages are used on thin logic boards as they are prone to failure within a few years of purchase, and lead free solder did not help the issue, well manufacturers dont seem to care about such design flaws. the logic board on a macbook is too flexible imo and the case not rigid enough, the unitbody macbooks helped these issues, bu theyre still to thin not cooled well enough and I doubt with thick enough logic boards either.

     

     

    so im guessing the next step is a bake of the board, probably using g clamps to apply pressure to both the vram chips and the gpu chip at the same time whilst being baked, as I think pressure and baking might be the only 100% way, relying on just one or the other is going to leave me at around 90%. i should imagine as the bga solder balls need to be forced into firm contact whilst the solder is made fluid and recooled, not sure if I have the energy for the operation as this is not worth it time wise.

     

     

    I kind of have it 90% stable, im using the penny trick on the vram chips, new thermal paste and a copper shim on the gpu chip, im using "Fan Control" system preference from macupdate, to set a fan profile ramp from a lower threshold 48 degc to 70degc for max fan rpm, and minimum fan rpm 3100rpm, im using temperature monitor lite set to open at login so I can keep an eye on all temps in the menu bar, I am also using SmcFanControl as fan speed readout in the menu bar, I tend to find though I have no graphic glitches during machine use when the temps get high watching full screen video for an hour or I may get a lockup, if I Avoid full screen and probably though not tested I also suspect full screen 3d games I dont get any lockups during normal use, which is a darn site better than beofre where the machine was display glitching on boot to desktop.

    With the fan settings tweaked to 45degC min and 70 degc max threshold for full fan speed and the shims and copper coins vram chip pressure, I can now watch 720p youtube videos fullscreen continuously without display glitches of any kind, im pretty certain as one of the previous posts mention some apple engineers investigation suggests that the major issue is with the vram chips on the A1150 A1151 with an x1600 ati chip, and this certainly holds true to my experimentation with placing pressure on them, therefore the ultimate fix for the display glitching must be Gclamp pressure and baking the logic board at the correct temprature and time, but for me my mod ive done above seems to brough the machine back in to full enough function to be happy.

    It might be the sodering comming undone on the GPU on the logic board (mine would stop working right after the GPU went above 140ºf), a friend of mine got mine working using a heat gun (reflow the soldering) seems the high heat is part of the issue

     

    You may also need new thermal paste (mine was like crushed crackers).     It is working fine now for me
