  1. Dear TechSpot Community,

    Hello, my name is Robert and I am new to this website. I am a parttime PC tech at Southwestern College. I have what seems to be a major problem with an instructor's laptop. It is a Thinkpad R51

    It had two sticks of 256mb RAM. I replaced the first stick w/ a 1gb stick and everything was ok.

    I few days later I replaced the 2nd 256mb stick (by removing the keyboard) with another 1gb stick. It booted up ok.

    The teacher reported getting an error message later that night telling her that there is a hardware incompatibility problem and to back up her information. But then the laptop booted fine the next day.

    Then she received the following error message
    A problem has been detected and windows has been shut down to prevent damage to your computer.


    If this is the first time you’ve seen this stop error screen, restart your computer. If this screen appears again, follow these steps.

    Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any windows updates you might need.

    If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use safe mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

    Technical Information:

    ***STOP 0x00000050 (0xc552B1C, 0x00000000, 0x804E70D5, 0x00000000)

    Beginning dump of physical memory.

    Now I get a momentary splash screen and then a black screen with a cursor flashing in the upper lefthand corner.

    This is after reinstalling to 2 original sticks. I also tested one of the original sticks in another laptop and it worked. Then I installed just this stick but this did not change anything. Does anyone have any ideas on how to fix it?

    Thank you very much

    generall caused by bad or failing ram or incorrect type of ram. Run memtest 86+ booted from a floppy or CD and run for 7 passes or more.

    Also read the upgrading ram guide in the guides forum.
