    I have a 5 yr old PC running XP Pro x64, Service Pack 2 with an Intel Pentium 2.8Ghz & 3GB ram. It was built and sold to me by an online store.

    Over the last year (or maybe longer), when I come back to the PC after leaving it for a varying amount of time from mins to overnight and switch the monitor on, the only display is 'No Signal'. When it does so I cannot escape out of it but have to switch it off at the power source and start it again.

    It then reverts the 'Quick Launch' to off and I have to enable it again. It also seems to clear some saved passwords and other fields.

    I've replaced the monitor and graphics cards and updated drivers. The problem is that it is intermittant and only happens at different times - last time was 2 weeks ago but then it happened twice y'day.

    When I switch the monitor on and get the 'no signal' the monitor light turns amber instead of its usual green.

    Any thoughts appreciated and thanks in advance.
