Monitor loses signal and then reboot

  1. 3 days ago, I started to have this signal loss+reboot problem.

    First day, it occured once at 5:55am
    Second day, it occured once at 6:00am
    Today, which is the third, it occured at 8:00pm and 2:00am

    Describing what happened in details..
    Basically, my monitor would randomly lose signal, but the background keeps going (such as MSN and music) , then it would automatically restart after few seconds.

    I thought the problem was overheat caused by graphic card, but that doesn't seem to be the case.

    Some information about my system:
    Motherboard: P5K-E
    CPU: Q6600
    RAM: 4GB
    Monitor: SyncMaster 2243BWX
    Graphic card: ATI Radeon 4800 Series
    PSU: RCA 550R
    OS: Windows XP SP3

    Is anyone able to help solve my problem? Thanks in advance.
    ( Will provide more information as I don't know what else I should include)

    Try updating your graphics card driver from the AMD support site. Do you have Microsoft's .NET framework installed?
