    Dell Dimension 5000, Win XP Home. I just reinstalled windows yesterday, everything was working fine. I think some xp updates download and I needed a restart. When windows loaded back up, it hung with the hourglass on the desktop. I held the power for 5 seconds to kill it. Now when I start the computer again I get a horrible alarm sound from the beginning, nothing even shows on the monitor. There are 4 LED's that light up "A B C D" - A + B are orange C + D are green.

    The thing is that I have had this noise before but I just restarted and it would be fine. This time it happens constantly I've restarted 20 times maybe, still nothing. Can anyone tell me what this might be? I've opened the case got rid of all the dust, and even tried plugging out the spare hard drives. I also made sure all the cards are plugged in properly etc

    What can I do now? All advice appreciated.
    Thanks

    A+B Yellow, C+D Green indicates faulty memory. "Reseat all DIMMs and restart the system to retest."

    Thanks. Strange I tried it once more just a few minutes ago and it started up no problem, weird. I'll try swapping around the DIMMs if it happens again
    Cheers for the reply!

    Dam it. It has stopped working again. I took out all the ram and reset. I also tried starting it with only some in, rotated them all. Still nothing.

    Suggestions anyone?

    Most likely over heating.

    It is ran for a while and stopped and ran for a while and then stops it's overheating.

    Assuming it is not something faulty, the most common problem is the CPU heat thermal paste/patch drying out and no long functioning.

    press f12 on bootup and run the diagnostics to see if it is the memory
