hi,
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.

any ideas?
thanks

Single long beeps are always memory related. Replace the memory with known good memory( have it tested first).

i placed the memory in a different slot and it does NOT beep any more.

it still shuts down after a few seconds. i do get to the windows loading either safe or normal mode, then it shuts down.

from my testing, when i unplug power cord to the ATX_12V on the motherboard, the computer does NOT shut down, but obviously the system will not start. When i then plug in the power cord to the ATX_12V on the motherboard, the computer shuts down sometime when the windows tries to load, either normal or in safe mode.

when i cleaned the computer i took out the CPU fan to clean it with the spray because it was way dusty. i am not sure if after plugging it back in caused this mess.

ok so i bought thermal paste, i reapplied.
i also bought a new PS.

can you get to the bios...usually by pressing the delete key as soon as you power up...

Sounds like a short with MOBO or CPU is not seated correctly.

so i solved the problem thanks to all of you.

1. the PS was not strong enough, so I bought a good one (550w), not a generic brand.
2. i reapplied thermal paste.
3. changed the cpu fan.

that did the job.

windows is now working and the computer is nice and quiet.

thanks for your help
