    Hi,

    Recently I came across a strange problem with my System. When I'm booting up the system, the display is scrambled and the system freezes and I cannot even enter the BIOS setup. My RAM is a DDR 512 MB Ram.
    I tried the following,
    1. Swapped the RAM slots, yet the problem persisted
    2. Removed the RAM and heard the consecutive beep sound heard suring RAM Error.

    What may be the cause of the problem?
    Attached the display with this post -

    I don't have any graphic card installed. It uses onboard VGA port. :unsure:

    then check LCD and try to run memtest. if LCD is ok and memtest fails even on another machine problem - RAM, if memtest ok, then mobo.

    LCD is ok, checked. How can I run memtest when nothing works incl. keyboard. When I press the ram hard or move it slightly, the pattern of display changed as shown in the picture

    I think you can forget about ram problems and ask yourself what's the real issue here. The rig boots but the picture is skewed and the system freezes. You have onboard video. Common sense says it's a chipset problem. Fix: Replace the motherboard and move on............:worthy:

    Glad to hear you found the culprit. I was misled by your post. I believed you had been using the PC for a while and that it ran fine. I thought the problem was "recent" which led me to believe the mobo had gone bad. There are no moving/vulnerable parts in a stick of Ram hence, on a properly maintained PC, if a Ram Dimm worked fine at one time it will continue to work properly into eternity under optimal conditions.
    There is no doubt in my mind that something has occurred recently regarding your PC that was the catalyst for this issue. Could be the ram was not locked in the slot properly or a power surge from a faulty/degrading PSU, or improper bios settings etc. Some unposted adverse event definitely happened to kill a good stick of ram, that much I do know........anyhoo, best of luck...:cool:
