  1. Hi,
    I have a problem with my pc.
    my computer screen turns red in colour or goes blank sometimes. I cannot say when it happens.
    my computer configurations are windows 7, 1gb ram,intel pentium 4 processor.
    I unplugged all the wires fixed them again,cleaned my ram,then its works normally.
    sometimes it takes more than a few times to get this right. I gave it for repair,by the technician said its working perfectly. but after a few days,I am facing the same problem.

    System specs... ?
    Is this a laptop, or a desktop?.
    If a desktop, swap out the monitor and see if the problem persists.
    .
    It sounds to me that the backlight of the monitor screen is failing.
    (after seeing the pictures, I am changing my mind!)
    On a desktop, just throw it away and get a new monitor.
    On a laptop... it is possible to do a repair.
    I did on a Dell, a number of years back,
    usually less expensive than a new laptop...
    but... may be more headache than it is worth.
    This may mean replacing the tube,
    or the circuit board that drives it
    or both.
    HTH

    It looks to be a desktop monitor in the pictures. Try and connect to another monitor to see if that is definitely the problem. If the fault is still there it may be the graphics card in the tower. That's something that I've found to fail fairly regularly. A separate graphics card is cheap and easy to replace. You just have to be careful about the type of slot and compatibility.

    As noted above... swap the monitor out.
    If the problem persists... then graphix card (as noted by bazz2004)
    I suspect, now, seeing the pix, that it is the graphix card.
    Sorry I did not see the pix initially.
    .
    If the other monitor is fine, then it is a monitor issue.
    At today's prices... not a major outlay.
    (For me, serviceable monitors can run in the $90-150 range)
    .
    Of course... you can test this monitor on another system too.
    .
    It is possible that just disconnecting a monitor
    and then reconnecting a new one may make the problem go away.
    (At least temporary, as you have already experienced).
    In that case... your card may be fine... and it just would be a "seating" problem.
    I cannot rule out this possibility as you describe getting temporary relief
    when you disassemble and clean and reseat parts.
    .
    If it is the graphix card... well cost depends on what you "need" it to do. :D

    It could just possibly be the lead between the tower and the monitor but my money's on the graphics card.

    If I were betting, I would not bet against you, Bazz2004.
    Here is information that points to why it may be the monitor...
    This is why I suggested trying to prove whether it is a monitor fault first.
    Cheap / damaged cable is another possibility.
    Damaged sockets at monitor or tower also a possibility.
    Without being able to handle the machine...
    my approach is just incremental. Rule things out as best we can.
