  1. Hi all,

    Im having problems.

    Yesterday my comp was all working fine.

    Then suddenly my monitor went black.

    CPU, etc are all running fine, but my monitor keeps showing me the black screen. (as if it is turned off) and the green light on the monitor keeps blinking.

    I restarted my comp, did every possible things, but no luck.

    When i remove the monitor plug from my display card, it shows "NO SIGNAL".

    Can someone tell me what's the problem and how can it be solved?

    Thanks in advance :)

    yo problem is abit wide,first u hav to know that its a hardware problem.key areas u should check first,find out whether it passes POST,does make that sound at the begining?2. remove and reinsert yo ram and cpu,(make sure blow dust first using compressed air or a blower).if nothing happens then use a seperate vga card.if stil nothing,check psu,if stil nothing,then replace ram.then keep us informed of your progress.Robin

    yes ,in most cases this is a memory error bios post did not get to the video controller to set monitor
    it can be a cpu error as well as a video failure

    good luck
    look for the beep codes
