dell inspiron 5100, pentium 4, win xp
after 5 - 10 minutes of normal use from a cold state, apparently it overheats as fan come on and quiclky steps up to full speed (sort of sounds like it's going too fast), once the top fan speed is reached (sounds extremely fast) the computer locks up, totally unresponsive, must be power cycled to restart. meanwhile the fan continues charging along at full speed the entire time until powered down. upon subsequent startup, the fan resumes full speed, but shortly after boot up it settles down to a medium speed for a time before the whole process continues.
if i prop the computer so that the fan intake (on the bottom surface) overhangs a table and theres a decent breeze, this may delay the fan from charging up and locking the computer.
now I've started using it set on top of on external fan, it mostly seems to be okay, until additional power consumption overhead such as video or especially audio becomes too great and causes that fan to charge up full speed and lock up the computer.
what do the experts suggest?
