MSI P7N Platinum SLI 750i freezes, even in Safe mode

I have had this board for about a year and a half. My sig should show the specs. I installed 8 gigs of G.Skill memory about 4 months ago, and everything has run great until about 3 weeks ago when I started to get random freezes. The monitor is still showing what was up, but the keyboard and mouse stop responding, as well as all other controls. I have had error logs analyzed and been told I may have a bad video driver, so I deleted it and let Win 7 install its own, and froze again. I logged into Safe Mode, it froze. I ran Memtest86+, machine froze while running it, then on reboot showed errors on the G.Skill memory, all 4 sticks. I put my old memory back in, still freezes. In fact, it sometimes freezes during the POST, when nothing but the BIOS is running.
Sometimes the machine will boot up and run for anything from 2 min to 30 min, then freeze. Sometimes, when I reboot it, it will not post at all, but just show a black screen. If I let it sit for 5 to 10 min it seems to boot again, but inevitibily freezes again. I got one error indicating a BIOS problem (BIOS checksum not equal) but only once. 
I am afraid to flash the BIOS, as a freeze then will kill the board. The freezes during memtest and POST indicate a hardware problem, and having 6 memory sticks go bad (two previous ones went bad) also indicates a bad board. Running HWMonitor shows no fluctuation in voltages or any high temps, so I am baffled.
Anyone have any ideas?

You don't need to connect HDD at all.
Get Live Windows or Linux  CD - one that has lots of testing utilities.
Check BIOS - frequencies/timings/voltages.
Well, the HDD is not the only problem. The only PSU available would power the MOBO, but cannot power my video card, and the board has no on-board video. I only own one PCIe card, so I am out of luck there. I did turn the machine on several times with a multi-meter connected to several 4-pin Molex connectors, and the power was correct and consistant (12.26v to 12.28v, no fluctuations over .01v during or after start up and 5.01v to 5.03v and 3.3v all the same). I know testing with the multi-meter does not show it under load, and is not the best test, but it is all I can manage.
On the Windows 7 forum, someone suggested this site  http://www.badcaps.net/pages.php?vid=5   
Several items here caught my attention:
Motherboard fails to POST.
Memory Test Fails.
Fails to fully boot (or even install) Operating System.
System randomly and frequently freezes.
BSoD or hard freeze under heavy drive activity (Either RAID, SCSI, or standard ATA). (This is questionable, the HD light is on, but I cannot hear it running)
Resetting the system after a freeze and the system will not repost.
(You have to completely power down then power back up.)
A physical inspection of the board shows no leaking or bulging capacitors, although a couple are not perfectly perpendicular to the board.
I am beginning to think the board is bad, and I found a good replacement on e-bay (NEW board) for only $90. It is selling rather well and with only 4 left I am inclined to get it before it disappears. This is the board:

Opinions?

  • Screen freezes, even in safe mode and in BIOS

    I’m working on a friend’s laptop: Toshiba, Satellite M65 - S9092
    Original problem: The laptop started shutting down after few minutes of use. (Probable overheating)
    Took the laptop apart and clean it out. The heatsink, fan and outlets were really plugged up. Put it back together and did a clean re-install, Windows XP. Had few issues with USB drivers not being recognized but worked it out. Ran stress test for a whole day, no problem.
    Worked for few days and then USB wasn’t being recognized again and the screen started freezing up. Re-installed os again but it is still freezing up after few minutes, and stays that way till hard shut down.
    Screen freezes even in safe mode and in BIOS. (No blue screens)
    Switched existing RAM’s around (2 - 512MB), one stick, two sticks, etc…still freezing up. Wanted to upgrade the BIOS but can’t get pass the screen freezing. Not sure if the motherboard may be shot from previous overheating or need new RAM. Don’t want to spend money till I’m sure I’m replacing the right part.
    Any assistance is appreciated.

    Hi there... I have a satellite A70 - S256 an it was freezing up the same way. I downloaded an OS named UBUNTU fron the internet free of charge. once you download it an burn it to cd you can then boot from it after a couple of tries ( due to freezing). When it boots select your language immediately and choose the option to run memory tests (both installed and BIOS) and let it do its thing for as long as it takes. you should boot from UBUNTU on another working pc to get familiar with it if you are not allready so that you make your selection quickly before it freezes.  You may have to reboot a few times depending on freezing while the memory test is in progress and how much progress is made. This procedure fixed mines and I never had those problems again.    

  • **!! SOLVED !!** MSI P7N Platinum SLI Stuck on Splash Screen

    Okay, so I got a bunch of new hardware for Christmas and finally the rest for my birthday this weekend and I am stumped.  I got all installed and when booting, I get the MSI splash screen with the spaceship and nothing else...just stays there on the splash.  Only one beep like my other MSI boarded PC and no more after that.  I have tried reseating all components including CPU, ram, graphics card and still no luck.  Also have tried with mainboard out of case on the box with all connectors plugged in.  My hardware is as follows:
    MSI P7N Platinum mainboard
    Intel E8400 Wolfdale
    Corsair DDR2 2 x 1gb
    nVidia PCI-E 260 fx card
    I have all else unplugged to eliminate as much as possible.  PLEASE help me salvage this because I have to say its been the most disappointing birthday ever this year LOL. Thanks guys!!!!
    P.S.  Also tried reseting CMOS many times including overnight unplugged and mainboard battery removed.

    OK everyone...problem is fixed.  As u all thought, the S-Spec of my CPU was not supported my the BIOS version (1.1) that the Mainboard P7N comes with...so the way I remedied the situation was to find (and purchase) a cpu that is on the cpu support page for mainboard that is supported by bios version 1.1.  I also must note, do not go by just the model number, go only by S-Spec number.  Once my Intel Celeron D 3.3 came today, started pc with a botable floppy (made by windows on my other machine) and flashed bios the old fashioned way with floppy disk.  After flash to version 1.3, put my CPU back in and what do you know...IT WORKS!!!   So got Windows installed and have been stable for about 6 hours now.  Thanks all who contributed...I love you all!!!  LOL

  • P7N PLATINUM SLI dont post at all!!!!!!!!!

    i bought a new msi mobo p7n platinum sli, after backing it in the case and connecting everything,it doesnt post,and it freeze on the msi logo..
    also the keyboard dont work at all, so i cant enter the bios,if ipress on del it gave me a black screen write in it as follows:
    A7380NMS V1.0  011508....
    system specs are:
    1. MSI P7N PLATINUM SLI
    2. CPU INTEL  E7400 2.8 GHZ
    3. 2x2GB KINGSTON DDR2 RAM
    4. XFX NVIDIA 9500 GT 1GB
    5. GIGABYTE PSU 550W
    CAN YOU PLEASE PROVIDE ME WITH THE SOLUTION,ITS A BRAND NEW PC
    THANK YOU ALL FOR THIS GREAT FORUM.....

    Remove mainboard from case and try running with just absolutely necessary components. Try reseating cpu and check if heatsink has proper contact to cpu's heatspreader. Try running setup with just one mem stick.
    Also provide full specs of psu as you can see in my signature.
    From the writing you reported (A7380NMS V1.0) it seems your board has bios V1.0 installed while your cpu would at least require V1.2 or higher (http://global.msi.com.tw/index.php?func=prodcpu2&prod_no=1373&maincat_no=1#menu).
    Possibly you might need to lend an older Core2 cpu to install bios V1.2 or ask the retailer to flash it for you. First step is of course to try eliminating other possible sources for the issue as listed above.

  • MSI P7N Platinum and 8800GT of 8800GTS in SLI with everest is FREEZE

    Hello,
    I want to warn users of the msi p7n platinum with the 750i chipset who use everest 4.50.1372 and a 8800GT or 8800GTS 512 mb (with a G92 CPU) in SLI that they can get freez problems.
    I got a extra 8800GT card and go SLI but the computer got random freezes after that.
    My system:
    Windows xp sp2 with an Q6600 2GB pc-6400 ram, 4 hd's (2 ide, 2 sata), dvd-writer and a dvd-rom. Latest 1.2 bios.
    It was very frustrated and also mailing msi support in The Netherlands didn't help (they thought it was a problem with the powersupply). The computer just got frozen with the last picture on screen and didn't respond at all (not a single error msg). Sometimes in minutes and other times in hours. Only option after that was a hard reset.
    To make a very long story short (i tried every beta bios out there with every bios setting) . I sold one of the 8800GT's and bought a SLI set with 8800GTS 512mb in the hope the problem was with the different brands of cards (EVGA and TWINTECH with the 8800GT's). But the problem was even worse with the 8800GTS 512mb G92 (from Point of View). So i take a look at the software and found out that the problem was with the everest monitor software that displays all kinds of info on my G15 keyboard. After i disabled everest i had not a single lockup anymore.
    Also the latest beta of everest that i downloaded yesterday gave the same problems!
    Everest was in fact the last program i disabled cause i used that to see what the temperatures of the CPU and GPU where at the moment the computer didn't respond 
    Mabye more ppl have this problem and are using everest and i hope that they find this thread Dunno if the problem is also with other brands and chipsets (like the 780i or 790i)

    luckyjan, thank you for your feedback on this.  Interesting find. 

  • Problem with MSI X58 Platinum SLI - IOH temperature !

    Hi guys.
    I have this PC configuration:
    - MSI X58 Platinum SLI ( Bios Version 3.8 - http://img822.imageshack.us/img822/6707/161020101249.jpg )
    - Intel Core i7 930 2.80 GHz box ( with Intel Turbo Boost running sometimes at 3.06 Ghz )
    - MSI GeForce GT240 1GB DDR5 128-bit HDMI
    - Corsair 6GB DDR3 1333MHz CL9 XMS3 Triple Channel Kit ( sets to AUTO and running at 1066 Mhz )
    - Corsair CMPSU-750TXEU
    - Ordinary case ( http://img828.imageshack.us/img828/4200/161020101246.jpg & http://img29.imageshack.us/img29/8480/161020101247.jpg ).
    - Windows 7 Ultimate 64 bit.
    I bought my PC components 2 months ago, so they are new.
    Now, guys I think that is a problem with my motherboard. When I turn on the computer in Bios I have this temps: CPU – 30 C (86 F); IOH – 71 C (159 F); System 30 C (86 F) - http://img687.imageshack.us/img687/394/161020101242.jpg. After 2 minutes the temperatures are: CPU – 34 C (93 F); IOH – 82 C (179 F); System 41 C (105 F) and 2 more minutes later the temperatures are: CPU – 34 C (93 F); IOH – 84 C (183 F); System 43 C (109 F). After 30 minutes of doing nothing I have this temps: CPU – 35 C (95 F); IOH – 85 C (185 F); System 42 C (107 F) -
    Guys it is normal with IOH temperature ? I am a little worried about it ( to be honest I am more than “a little” … I am worried a lot ).
    Ok, I know I don’t have a good case but in 3 weeks I should receive this Thermaltake Spedo Advance Case (http://www.thermaltakeusa.com/Product.aspx?C=1121&ID=1829) and I will buy a new CPU cooler ( I don’t know yet wich one – maybe Corsair CWCH70 or Noctua NH-D14 but I have to see the case first … to be sure there is a plenty of space for those coolers ).
    Pls help me with that IOH temperature. It is normal ? What if I intend to make a little OC ( lets say CPU to 3652 Mhz and RAM to 1333 Mhz … but also I will ask for your support ! ) my motherboard will burn ?
    If it is necessary I will contact my retailer and send him back the motherboard but … I like MSI a lot.
    Thx guys for your support !

    Hey guys,  
    Here is a nice cheap alternative.
    Here is my story about the same issue.  I found it after looking at why my computer freezes sometimes. Not very often but enough for me to do some investigation.   I noticed my IOH temp was a whopping 117 degrees Celsius. lol.  Surprised my mobo didn't burn out by now.  I wanted to evaluate the situation with the heat sink and decided to take it off.  After taking it off I found extremely crusty purple compound on board the chipset and the heatsink.  I took me FOREVER to scrape it off. it was almost like a cement which I found odd.  After scraping and cleaning the surfaces with alcohol, I placed some silver compound on and proceeded to put it back on.  
    Well, upon hooking everything back up I was still at 95 to 103 degs.   Now I started to really look at the options to replace this.  I had SLI config which means I had to do something clever with the southbridge as well.  A nice thermaltake chipset solution w/fan and a low profile copper southbridge with shipping was about 45 bucks.  Hmm ... This is a sure fix from the threads I have read and its really kid of expensive to fix a simple defect. the problem is not necessarily with the heatsink not being sufficient.  Its the combo of the compound used vs the amount of pressure applied between the heatsink and chipset.  It was completely unacceptable.  I knew this right away when I was watching the temp and then I would press on the top of the IOH heatsink and I would watch it drop another 15 degrees in less then 10 seconds. The springs are extremely weak and not effective at all in transferring the heat from the NB.
    Here if my fix.  Cost me less than a dollar at the hardware store and it works ideal thus far.  Do this at your own risk.  Doing this will probably void any warranty too.   All my problems are solved and I am running at 57 degrees, YES, 57 degrees with the stock heatsink and no additional cooling.
    For one scrape all that old crap off like I did. Apply your new compound. But when you go to replace your heatsink, use the following method.  The trick is to use metal screws with a mobo washer, original springs from the plastic studs and a nylon locknut.  Use screws that are the same diameter and length (maybe a tad bit longer) as the plastic retainer studs.  Also grab a few of those red nylon mobo washers too, were gonna need them as well.
    After scraping and applying compound, reassemble as follows.  Screw with washer inserted into the back of the mobo so the threads are out front.  The plastic/nylon washer is betweeen the screwhead and the back of the mobo as a insulator. Put the heatsink on. With the threads thru the heatsink already, put the springs on and start spinning on the locknut.  I torqued the nut down on the spring until the spring almost became fully compressed.  The purpose of the spring here is really to prevent you breaking something and at the same time using the max force of the spring since it weak to begin with. Thats why we need to compress it down pretty much all the way. There will be little to no room in the spring at this point.  The heatsink at this point should be pretty solid to the board as well.  I noticed with the plastic studs before the heatsink would wobble if you gave it a little rocking back and forth before.  Not this time. Shouldn't move much if at all.  Remember not to torque down too much. You don't want to go beyond the springs compression. Even if you did by accident, its better then not using a spring at all. If you feel that it starts to feel tight when torquing, you torqued too far. Stop an backup a 1/4 turn or so.  It is also very important to make sure both torques are equal on both sides as well. Alternate sides when torquing down.  I could tell by how much thread I had left on both sides and by looking for any uneven sides.
    To summarize, the compound is a problem no doubt.  After you resolve the compound issue, its all about the adequate pressure between the heatsink and the IOH.  Much like the amount of pressure needed between your CPU and your heatsink give or take. And the pressure that would be as an aftermarket solution like the thermaltake chipset cooler. You dont see cheesy springs on that.  Wake up MSI. Simpy using a more effective spring could save MSI some cash in the long run. I envision a leafsprin design like the thermaltake chipset one.  The heatsink design could be better, sure, but the design itself is not the problem. Replace the heatsinks if you would like to, if your overclocking and stuff.  Funny, this board I have is a refurb too and only had it for a few weeks. Figured they would have done something about it.
    Sorry the pics are not the best. Here is about as close as I could get to the finished product

    Hey guys ,
     Can someone please help me ? I have been getting BSOD for along time now and then i get a windows recovered from serious error when it boots back up , i always send in the error report and usually it says a driver problem but i have re-installed every driver servral times and and re-formated my pc sevral times to try and get it to run right . Now i finally got a different report back from windows error reporting saying a "Non Compatable BIOS is the cause " here is the error report screeny i took and uploaded to flickr  http://farm4.static.flickr.com/3538/3349882297_4a3194e3df_b.jpg and this is another screeny in flickr of my BIOS in MSI Info View http://farm4.static.flickr.com/3445/3349882397_ef282a33d2_b.jpg , i believe i have the newest BIOS installed and the correct one also and have been running that version for along time . When i first setup this system i could not get my Q9550 to boot at all with this mobo till i updated the bios to the P0B6 but have never had it stable from BSOD . My Specs are Q9550 "Core 2 Quad Yorkfield SLAWQ Q9550 333 2.83 12M " / MSI P7N Platinum 750i SLI / OCZ Vendetta CPU cooler / 4GB- 4x1GB OCZ FLEX DDR2 1150 / OCZ GameXtreme 1010W / 2x - XFX GTX260 Black Edition in SLI / 1TB Seagate HD .
     Also i had just tried the live update but it says there is no new updates for bios , when i first did the update i used a 3.5 floppy and flashed the bios to the ver i currently have now because there was no way for me to use the live update with XP Pro 64bit , Now im running Xp Pro 32bit w.

    I suggest that you clear CMOS and use flash it to the BIOS v1.1 under the MSI website for your board and see how it goes.
    http://global.msi.com.tw/index.php?func=downloaddetail&type=bios&maincat_no=1&prod_no=1373
    LOL thats funny !!!!!  1.1 is what came installed on the mobo and is not compatable with the Q9550 it will never boot to bios using 1.1 with a quad core ! Thats the first problem i had thats why i explained all the steps i had to go through to get this mobo / cpu to boot with the help from MSI tech support !

  • Memory not recognized on MSI Neo4 Platinum SLI

    I just installed another 512mb of RAM on this system:
    MSI Neo4 Platinum SLI
    2 x 512mb Corsair XMS XL PRO
    1 x 512mb Corsair XMS XL (the one that doesnt work)
    IDE HDD
    Windows XP PRO
    BIOS, and every program i run that can see system specs shows that the infact all 3 Sticks
    are recognizable. Though...Windows and a program that shows me my physical memory max both
    point out i have only 1 gig of RAM!?
    It's there, just not being used?
    Now the only difference with the XL version and the XL PRO version is the heatspreader,
    everything else is the same....so nothing should be conflicting.
    Since the computer somehow knows all my part's details..im thinking just because
    the new ram doesnt have PRO that it may not be recognized to work together.
    Even so...ram should downclock etc with this motherboard...so this stupid little name
    issue shouldnt cause the computer to ignore the ram!
    I tried switching DIMM slots, no luck.
    Any ideas?

    It's a AMD64 dual memory channel system motherboard/CPU.
    Valid memory populations are
    1.stick in one of the channels .(single mode 64bits)
    1.stick in each channel .(dual mode 128bits)
    2. sticks in one of the channels.(single mode 64bits)
    4.sticks ,2 in each channel.(dual mode 128bits)
    3 sticks is n/a.
    The population on memory controller , it's initialization and modeselection , single/dual mode is chosen by the A64 cpu.
    It's been said that later rev.E cpus can autoselect unmatched population between channels (of e.g 3.sticks) and
    set the whole memory pool in single mode.
    But i have never seen anyone successfully test/run it .

  • NVidia's nForce drivers on P7N Platinum SLI

    I just wanted to query the forum and other nForce mobo users to see if they had any problems with using the nForce chipset drivers provided by nVidia on their website. I currently use the chipset drivers provided on the MSI website for the P7N Platinum mobo (750i northbridge, 430i southbridge) and they have outperformed all other drivers supplied by nVidia, including the latest 15.45 package (difference of 500-800 marks in PCMark05). Is this common on nForce boards? Are there certain parts of the nVidia drivers that don't work with the P7N, which would make MSI have to create its own driver package for the board? Anybody else have issues with nVidia's nForce drivers?

    I have a P6N, the slightly older brother of your board and yes I had troubles with one of their Nforce drivers in Vista.
    Like you im running the ones from MSI, somehow they do the trick much better.
    They are older, but who cares 
    Updated it once, but had to roll back due to all sorts of troubles, so íll stick with them.
    In Win 7, im running the 15.35, cause MSI has no drivers for Win 7 for my board and so far, no issues.

  • Various advice needed to overclock cpu using my MSI k8n platinum sli

    Hey guys, i recently overclocked my amd 64 3500 cpu to 2.4ghz (from 2.2ghz) i was wondering if any could tell me how high i can get this cpu up to using the msi k8n platinum sli mobo.
    At the moment the cpu's temp goes to 40-45 oC.
    If i can overclock the cpu some more, can anyone give me detailed instructions on how to overclock it as i'm computer newbie.
    i'm using the standard amd heatsink and fan so i know that will comprimise the potentail of the cpu's overclocking capability, as i heard that some people managed to get their cpu up to 3.ghz with a high quality fan, so i was just wondering if anyone can tell me how high i can get my cpu frequency with a standard fan as i really don't want to risk damaging the cpu if i go overboard.
    Thnx in advance.
    P.S Does anyone come across any green flashing lights while playing their games when the high performance settings mode is set to optimized in bios settings mode??

  • P7N platinum sli and qx9650 overclock issues

    Hey all,
    Just wondering if someone could help me with overclocking my qx9650 on my P7N platinum sli.
    I have tried throwing all kinds of voltages at the cpu, fsb, and nb and I still can't run stable for over a few seconds. I thought it might be due to a fsb hole and have tried a range from 1550-1650. My goal is to get it at 400mhz(1600 in bios) and get a 5:4 ratio with my ram at 1000.  I tried updating to the p06 performance bios from ami 1.3 and still can't get it stable. I don't want to end up frying my board. I got it to run stable at 350 for an hour in prime 95 but would really like to achieve 1600.  at 350x8.5 for 1500 my temps did not get above 54c under full load
    I am not looking for a huge oc, just get to 9x400 for a 3.6 ghz clock speed for 24/7 use. I ran prime 95 for 5 hours with everything at stock so I know it is not a bad cpu, ram, mobo. I also ran memtest86+ at stock and every test passed. I have d.o.t disabled, eist disabled, and spread spectrum disabled.
    Memory timings right now are 5-5-5-18-2T at 2.1v and memtest+ passed with those settings at speed 800mhz.
    any suggestions would be great

    just wanted to let everyone know that i got it stable at 3.75ghz for 26 hours in prime 95. Don't know why but it still won't boot from 1550-1650 (must be a FSB hole or something) so i just put it at 1500(375) with a 10 multiplier and ram at 1000 for a 3:4 fsb:ram ratio.

  • Msi K9N2 Platinum SLI and Windows Server 2003 r2 32 bit edition

    Does anyone know or have tried to get this board to work on server 2003 32 bit edition. I seem to get past the raid part but the realtek 8211bl and audio are giving me fits. Any links to good drivers would be appreciated.
    Spec of system:
    Amd 9950 Quad
    4 gig memory
    Msi K9N2 Platinum SLI
    2 500 gig sata

    Ok overall solution this board works awesome with Windows Server 2003 Enterprise R2 with Sp 2.
    Here are a few tricks for the Co processor controller, Sm Bus, Audio and finally the networking controller.
    When you finally get windows loaded. Make sure you put Service Pack 2 or 3 on before u install drivers.
    The raid drivers are simple for the 32 bit version use the xp ones and load both raid drivers during setup. Requires 2 floppys or Slipstream disk.
    http://global.msi.com.tw/index.php?func=driverfile&dno=7067&i=2
    Once you get windows loaded and Sp 2 or better on. Stick in your windows vista driver disk in. Once there do not install anything.
    Goto device manager and update drivers on all that are with the yellow ? excpet the networking drivers and just do an automatic search and boom your done. It will also ask you if you want to enable your audio at this time. Do so but do not reboot untill u finish installing all drivers but networking. Than reboot pc
    Last part is for networking card. We need you to be in safe mode for this. So once u install all drivers and start reboot hit F8 and goto safe mode. Once in safe mode take out vista driver disk and put in xp driver disk. Goto device manager and update driver on network controller and let it do an automatic search and it will installl it. It will say it needs to be rebooted to work. Go ahead and reboot and your networking card will work.
    Probably simpliar solution. But just wanted to give my help.

  • Can't Boot after crash, even in safe mode!

    My Mac froze while idle with Lightroom open. It may have hung while remotely copying something off an external hard drive.
    But now it won't boot even in safe mode with all USB peripherals detached (including the hard drive that I might have been copying from).
    In and out of safe mode, I get the same behavior. After the sound and the grey apple appear, there is also a progress bar, which I don't recal seeing before. It takes about 30 seconds and the progress bar advances about 10-15% of the way and then just power's off.
    Is it the main disk drive?
    This is an iMac that is several years old with all of software update applied. I don't believe that any software updates were applied recently. I assume that the 10.6.3 update was installed.
    Is it the main disk drive?

    I had the same problem on my MacBOOk Pro and iMac on 14th April - i had to reformat the harddisk and could restore from my Timemachine backup to the last 10.6.2 state only. Both happended after updating to 10.6.3. But my laptop was sluggish. Based on feedback, I reformatted my hard disk and carried out a fressh installation from my snow leopard disk (10.6) and updated it to 10.6.3 using the 10.6.3v1.1 combo update about a week back. The machine was definitely faster - but yesterday, the same problem reoccurred - the machine froze and would not boot even in safe mode. Repairing the hard disk using the boot CD did not work either. Just now I reinstalled Snow leopard from the OSx CD - it has replaced the OS and left all apps and data intact. I have upgraded it to 10.6.2 only.
    My desktop iMac has been running without problems on 10.6.2 for the last 3 weeks. In my opinion, the problems of freezing (reported by others) and this one here are all related to boot sector corruption due to some problem in 10.6.3. There have been some reports suggesting that after 10.6.3, the CPUs are heating up more. The CPU temp was close to 70 deg C when on 10.6.3 - it maybe that some change after the update makes the processor overrun leading to this boot sector corruption - it generally happens slowly over days or weeks slowly accumulating to a break down point.
    My suggestion from my experience over the last one month, is stick to 10.6.2 - don't update to 10.6.3. I am hoping Apple will fix the problems in 10.6.3 update soon.

  • In updating FF, message says to restart to complete previous upgrade. I reboot, with same message. Attempted to uninstall. Same message, even in Safe Mode.

    I tried to update Firefox and repeatedly get this message: "Your computer must be restarted to complete a previous upgrade of Firefox. Do you want to reboot now? " If I click no, nothing happens. If I click yes, it reboots, and I get the same message all over again. I have tried to uninstall the program and get the same message, even in Safe Mode. I tried to start with a previous system configuration, but the computer would not give me any previous configuration dates. I am using XP, and I deleted Internet Explorer, so I cannot access the Internet on that computer. I have tried to install the update by downloading the upgrade on a different computer and transfer it on a flash drive, but I got the same results. If I go to Control Panel/Add or Remove Programs, it says I have Firefox Version 13.0.1. For approximately 6 months previous to this incident, I have been getting a message when I load Firefox, that says that it could not install an attempted update. If I clicked okay, at least it would still run the old version. Now it won't even do that.

    Download a fresh Firefox copy and save the file to the desktop.
    *Firefox 20.0.x: http://www.mozilla.org/en-US/firefox/all.html
    Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
    *Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.
    Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
    *It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
    *http://kb.mozillazine.org/Uninstalling_Firefox
    Your bookmarks and other profile data are stored in the Firefox Profile Folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

  • As soon as I open Firefox it crashes, even in safe mode. I've tried all the options to fix the problem but to no avail. My crash report number is: 1326236186. I hope this helps!

    Firefox crashes as soon as I click on the icon. Even in safe mode. I've tried all options of resolving this problem but nothing is working. I really hate using Safari and Chrome. Please help!

    Scan your computer in safe mode for bots, malware, trojan's and viruses. Remove any Found and reboot. If Problem still exists, go to control panel, add/remove programs remove firefox. and then download and reinstall firefox. Remember to always close as many running programs like messangers and widgetts when installing any program. This should fix your problem. only other option is to do a system restore to when you were not having any problems, this works 90% of time.
