Laptop (p205d-S7436) freezes on startup only with two (2) (1GB + 1GB) RAM modules

it works fine with just one 1GB chip in any slot
Laptop was purchased in Nov 2007 with 32 bit Vista and 2GB RAM (1 + 1) It worked fine for approximately a year, and then started freezing randomly, usually after logon. Removing any RAM module fixes the problem (but I obviously want to run it with 2GB)
I've been applying practically all updates (although I've reverted the LAN driver, the Audio driver and the Video driver to the original 2007 versions). Still freezes, even in Safe Mode (without networking)
again, as long as I remove a RAM chip, everything works fine. What could it be?
Please help

Note that you don't need bluetooth for your mouse and keyboard to work since you use the dongle.
Thanks for the reply terminator! I tried removing bluez but got that a lot of other packages depends on it so what I did was install blueman and paired the mouse from there.
Now it pairs fine and works automatically even after a reboot. But, there's still the issue that I have to remove the dongle and connect it again on boot for it to work.
Any ideas?

  • Please Help :( iMac 20" refuses to boot up with anymore than 1gb ram?

    Please Help iMac 20" refuses to boot up with anymore than 1gb ram?  It was fine 4 days ago and had been working with a 1gb stick in one slot and a 2gb stick, which had replaced the orignal 1gb stick that I got it with, in the other and it had shown 3gb of ram and was working just fine with that since November?  It went to sleep briefly 4 days ago while I was waiting on a customer and I came back to try to wake it up and it never would forcing me to hard boot it.  When I did that it would only go to a black screen with a solid white light on the power indicator.  Over and over again and same thing.  I read and tried every suggestion I could possibly find in this and a few other mac forums to no avail.
    I finally after reading about RAM issues etc.  I decided to power off and take out the ram sticks and try them one at a time in each slot.  So I took out the 2gb stick and did the SMC reset and it would boot up and work just fine with the 1 gb of ram.  So then I went through the same process with the 2gb stick and it would not boot up only go to a black screen with white solid light again (NOT flashing).  So then I tried the other original 1gb I had replaced with the 2gb and it worked just find like the other 1gb.  So then I tried just 1gb stick in the other ram slot (back facing one) and with just the 1gb strip it booted up and worked fine.  Tried it with the other 1gb stick and once again that one too worked just fine.  So I determined it wasn't the slot itself I thought?  I then tried the 2gb in the back slot and it would not boot only go to the black screen white solid light deal like before.  So I thought well ok it's obviously the 2gb ram must have somehow went bad (even though I have only had it since November) and I thought well I will just use the (2) 1gb sticks in each slot and then that will at least give me 2gb because only 1gb really ***** LOL.  So I proceeded to go through the same shut down process installed both sticks (I always push them to I feel them click and my fingers have a nice indention on them) reset the SMC and turned the power one and.... It would only go to the black screen with white solid light on power indicator????  I went through the same above process at least 3 times and again today a few times and I can't figure it out and I tried to search and search and I couldn't find anything like what I am experiencing.....What happened?  Please help this slow Imac is killing me.  It will work with 1gb ram only nothing more?  Here are the specifics of my Imac.
    It is a 20" Late 2006 Intel Core 2 Duo 2.16 ATI Radeon X1600 256 MB graphics card and Ram with now only 1gb (did have 3gb) and I am running OSX Lion 10.7.5

  • Freezes on startup screen with new Battery

    laptop works fine with old Battery just battery will no longer hold a charge installed a new Battery freezes on startup screen ran battery test ok got a 2nd new Battery using the numbers off the old one same thing followed hp noteboook pcs testing and calibrating the battery everytime the first part says battery ok the 2nd part says na. reinstall old battery laptop works fine

    Thank you for visiting the HP Support Forums and Welcome. I have read about your Compaq-Presario and having an issue with the New battery. Here is a link to test and calibrate the battery.
    Plug the power adapter directly into a functioning wall outlet. Do not plug it into a power strip, surge protector, or secondary power source as this could cause and issue.
    If that does not help try the Microsoft ACPI-Compliant Control Method Battery is basically the driver that communicates between the computer and the battery. There is a chance that it is corrupted. It is reading the battery level wrong, so the computer thinks the battery level is higher then what is actually is, so when it runs out of juice it shuts down.
    Step 1. Go to Device Manager
    Step 2. Select Batteries
    Step 3. Right click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there
    Step 4. Click Uninstall
    Step 5. At the prompt put a check in the box to remove the current driver
    Step 6. Shutdown the computer
    Step 7: Remove the battery for minute and then put it back in
    When the computer comes back up it should automatically find the driver.
    Step 8. Go to Device Manager
    Step 9. Select Batteries
    Step 10. Right click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there
    Step 11. Click "Search automatically for updated driver software"
    Do the same thing with Microsoft ACPI-Compliant Embedded Controller.
    Hope this helps.

  • Satellite Pro L100 crashes when loaded with 2 x 1GB Ram

    Hi,
    Satellite Pro L100 - came with 512MB ram - Too slow - expanded using 2 x 1GB ram from crucial technology, speed 555MHz
    When both 1GB installed, laptop crashes on the XP boot screen - then loops, crashes, loops, crashes etc...
    Tried alternating the slots and using ram independantly - No change - so ruled out faulty ram
    Tried shippped memory with 1 x expanded 1GB ram - All OK.
    Tried every orientation conceivable - just crashes when expanded ram is loaded to its specificed max - 2GB.
    Upgraded BIOS to 3.2 - no change
    Does anyone here have any other suggestions? I fear my last resort is to dig deep and get more ram from a diff OEM, prefer not to hence asking politely for help
    Thanks in advance,

    Have you ran Memtest?
    Download the bootable Memtest CD ISO from www.memtest.org and run it for a few passes.

  • FireFox 4 beta 8 freezes on startup, 25 CPU usage, over 2 GB RAM usage

    Safe Mode does not work, the same thing happens if I do that. I have tried uninstalling, restarting and reinstalling but the same thing still happens again.
    What else can I do?
    I have also tried going back to the 3.6 release of FireFox but it crashes instantly on startup, even in Safe Mode.

    You should make sure that you are using firefox 4 in a separate profile from firefox 3, use [[Profile manager]] to help you do that.
    I think by default firefox 4 beta is installed in a separate location from firefox 3, but you still need to make sure you have separate profiles.
    Try to sort out the problems with firefox 3 first. See
    * [[Safe mode]]
    *[[Basic troubleshooting]]
    With Safe Mode do not initially make changes in the first dialogue window you see, instead just click on the 'continue' button
    Creating a new profile is a one of the troubleshooting topics covered in the above article but remember it is good practice
    - to backup your bookmarks manually
    - use an empty folder for each profile
    - keep unused profiles (just stop using them &/or rename them) do not delete them (At least untill you are absolutely certain what they contain and what you could loose if you do delete them, especially if they share folders)
    After you have managed to use safe mode successcully you may be interested in

  • Office 2008 with G4 MacMini (1GB RAM)

    Hi! Does anybody see this as a problem? I have heard that Office 2008 will slow the whole system down to a crawl. Anyone with this experience? I am currently using Office 2004 and it works fine, but should I upgrade or not???

    I suggest you wait. I have heard that on PPC machines Office 2008 is slower than 2004. Plus, you don't have much RAM.
    I am very happy with Office 2008. If you did upgrade, you would get better support for PDF and other images, support for the newer file formats, and better toolbars. Those new features plus Intel compatibility make it a good upgrade for me.

  • U550 - Windows 7 - 0x000000A5 BSOD with 1Gb RAM

    A friend of mine asked me to install Windows 7 on her IdeaPad U550. So I did. Everything worked at first. But after installing drivers and some software, I started getting BSODs on widows startup:
    The BIOS in this system is not fully ACPI compliant. 0x000000A5 (0x00001000, 0x00000000, 0x55AA55AA, 0xFFFF0091)
     I tried reinstalling windows 7, but windows setup fails with the same BSOD message.
    Some further experimentation has brought me to the following conclusions:
    1) the laptop works fine with a 1Gb memory module installed.
    2) the laptop doesn't work with more then 1Gb RAM installed (U550's shipped with one 1Gb and one 2Gb modules installed)
    3) the problem isn't in the installed OS (DVD booted windows setup also fails)
    4) both RAM moduls are working properly (tested them on my other laptop)
    5) both RAM slots are working properly (windows starts with 1Gb RAM module in either one of them)
    6) there're no BIOS updates for Lenovo IdeaPad U550.
    There IS however some kind of problem with the battery. There's a notification in systray recommending to replace it. Taking the battery out or placing it back in doesn't seem to make any difference in regard to BSODs.
    So, my best theory at the time is this: the battery (and/or it's absence)  somehow causes the ACPI-related errors. Now, that sounds kind of stupid to me, and I can't just ask my friend to buy a new battery if I'm not even sure it's gonna fix the problem. That's why I need your help, guys. Any help is appreciated.

    Well I deleted the VM and re-created it, and reloaded Windows and all my software, works fine now.
    Thanks for all the help.

  • PB with 20" freezes on startup

    Hi there
    I've had a new 20" connected to my not-very-old PB for a couple of weeks. Periodically I get a freeze on startup (computer gets through the first 'white' screen with the apple on it, it goes to the blue screen where normally the progress bar should pop up, but it hangs... a Mac bluescreening?). The only fix I've found is to hold down the power button and restart. Sometimes it happens a couple of times in a row...
    WHAT I'VE TRIED TO FIX IT:
    Basically, I've stopped using any of the cabling other than the DVI; so I don't use the USB/FW ports on the screen (a bit annoying). The only other recent addition to the system is an external (Mac) keyboard (the cheapo wired one) and I've tried unplugging that fella too, so the only external device connected at startup is the DVI port for the 20", but no joy, still the odd freeze.
    This isn't life and death, but it's a bit of a pain... I couldn't find this on the forum, so it doesn't seem to be a known bug, but I thought I'd check anyway...
    Thanks

  • My 2011 early MBP pro 15 freezes at startup with distorted image

    My 2011 early MBP pro 15 freezes at startup with distorted image, and sometimes its blank screen, I have also noticed that the machine heats up quickly at the same time.
    I got this problem few weeks ago when it is running windows 7 in vitual machine. Firstly I used a software to disable the discrete graphic card and it backed to work for 2 weeks until the OS got an update (might be a firmware update since it required restart). Now it stops working completely.
    I have try two hard drive (I have put in a SSD few months ago) and run the command line disk check on both of them, nothing wrong.
    I tried to run disk utility/time machine at start-up, distorted screen or just blank
    I tried to reinstall rams, did not work.
    Any other possible solutions?

  • G5 freezes at startup, get grey screen with logo, but no spinning gear

    As subject says, I get the Grey Startup screen with aple logo, but no spining gear.
    do i need a new install of OS X? Or ???

    Hi wampaskitty, and a warm welcome to the forums!
    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair. Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
    If that doesn't work, Boot off your original G5 Install Disk while holding down Option/alt key to select AHT, then run the extended Apple Hardware Test.

  • My Laptop is freezing during startup

    After failing to be able to get windows loaded under bootcamp when I tried to restart my machine it starts the startup screen with the dial circling then it stops after a few seconds with out getting to operational state. I did try to reformat the partition for the windows side. Is there a way I can reformat the whole drive and reload my software?

    Have you attempted Disk Repair in Utilities? Are you still using 10.5.8 as your profile suggests?
    As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
    You are now in a perfect position to do a
    SMC RESET
    http://support.apple.com/kb/HT3964
    Shut down the computer.
    Unplug the computer's power cord and ALL peripherals.
    Wait 15 seconds.
    Attach the computers power cable.
    Wait another 5 seconds and press the power button to turn on the computer.
    It is the 5 second timing that initiates the reset.
