    T21 - crash sometimes after boot, sometimes during boot

    A week back I was decoding/encoding a DVD with an external DVD writer connected to my thinkpad T21. The DVD came out fine, but immediately the system crashed with the screen going ghostly white/whitish.

    The CPU was working 90-100% capacity for almost 2-3 hours while doing the decoding/encoding process.

    At times the system boots and works fine for 5 minutes, sometimes it hangs right in the middle of the boot process before the login screen appears.

    There is not time to install a new version of the OS as the system crashes during the installation process.

    I tried the following:

    - tried another hard drive
    - disabled lots of devices, especially USB ones which might cause such issues
    - uninstalled video drivers
    - opened up the system, cleaned up everything
    - removed the fan/CPU case and cleaned up the accumulated dust
    - put the system on the side, switched on the table fan and let the air blow to the CPU case and switched on the system

    Still the same old problem - crashes while booting or 1-2 minutes into booting.

    Does anyone has any idea what could be the issue?

    the cooling power in the T2x laptops was very weak. I have a T20 and if I do compiling (linux) the 700MHz p3-m goes up to 91C. The reason being the heatsink doesnt make direct contact with the die of the cpu. Instead there is a thermal pad inbetween the two.

    So if there is enough heat for a long enough time, your thermal pad might have melted enough to now not make any contact with the cpu die.

    Thus your computer freezes/hangs/reboots after a certain while since its heating up and theres probably nothing to cool it down.
