    I have a problem with a kt400 mobo with amd athlon xp cpu which was overheating.
    I've cleaned out the heatsink etc refitted with paste, the fan is working ok and the temp is around 39c but the symptoms persist.
    The PC will boot up ok and run until everything is started then it just locks up, the mouse pointer moves but clicking does nothing - neither does ctrl-alt-delete, and the only way to shut down is with the power switch.
    I tried known good memory without any change so do I go for a new mobo, cpu or both?
    Any ideas please.

    PS. tried a new mouse as well.

    If you are using WinXP I would try a repair install of the OS before getting as drastic as changing major components. following are teh procedures

    XP Repair install
    1. Boot the computer using the XP CD. You may need to change the boot order in the system BIOS so the CD boots before the hard drive. Check your system documentation for steps to access the BIOS and change the boot order.
    2. When you see the "Welcome To Setup" screen, you will see the options below
    This portion of the Setup program prepares Microsoft
    Windows XP to run on your computer:

    To setup Windows XP now, press ENTER.

    To repair a Windows XP installation using Recovery Console, press R.

    To quit Setup without installing Windows XP, press F3.
    3. Press Enter to start the Windows Setup.

    do not choose "To repair a Windows XP installation using the Recovery Console, press R", (you Do Not want to load Recovery Console). I repeat, do not choose "To repair a Windows XP installation using the Recovery Console, press R".

    4. Accept the License Agreement and Windows will search for existing Windows installations.
    5. Select the XP installation you want to repair from the list and press R to start the repair.
    6. Setup will copy the necessary files to the hard drive and reboot. Do not press any key to boot from CD when the message appears. Setup will continue as if it were doing a clean install, but your applications and settings will remain intact.
    7. Reapply updates or service packs applied since initial Windows XP installation. Please note that a Repair Install using an Original pre service pack 1 or 2 XP CD used as the install media will remove SP1/SP2 respectively and service packs plus updates issued after the service packs will need to be reapplied.

    If you haven't done a memory diagnostic, that's the first step. It's VERY unlikely that your processor is the issue. It might be the MB, but I'd suspect memory first.

    Microsoft Memory Diagnostic

    Test in this order.
    1 Run memtest
    2 Test the hd with the mfg's utility for checking the drive
    3 If both of those checkout ok, give the mb a VERY close inspection with a bright light. Look for bulging / leaking caps on the board.
    4 Test the power supply. The easiest way is to swap in a known good unit.

    CPU would be the last thing I would suspect. They are really pretty hard to hurt unless you overclock / over volt them.

    Thanks for your help guys - as usual I got a PC with two problems!!
    The CPU was overheating so I cleaned a large amount of dust from the heatsink and although the CPU no longer overheats the problem remains.
    I booted into safemode and ran some scans and it turns out the whole thing was riddled with spyware/malware. Ewido, Adaware and Spybot have sorted it all out - problem solved.
