i have a computer here which i cleaned with a computer dust spray. my family member was complaining it makes a lot of noise. i noticed the pcu fan was so dusty, i cleaned it with the spray.
when i was done, i started the computer and i get this continious long beep. i get to the post stage and sometimes i see the win xp loading (or safe mode), then the computer shuts down.
i took out the fan again, placed it back. still nothing.
i took out the RAM, placed it back and still nothing.
i took out the battery, places the RAM in a different slot, and the computer loaded without the beeping sound, but it still shuts down after about 20 seconds.
