Heat Problem, lack of Thermal grease maybe ?

[leon]

Hi Guys, yesterday i asked a question why my computer was making a continuous beeping noise.

All programs work fine but it beeps all the time.

Someone suggested that it may be a heat problem, and seeing that i cleaned it including the CUP and fan assembly i removed the thermal grease from both surfaces, and with not giving it a though put it back together with the beeping still very active.

Three days ago it started to beep every minute or so, than slowly progressed to shorter intervals and now it is continuous, so could this be the reason.

The key board seems fine, and noting changes if i pull out every lead from the computer, so what now, any suggestions would be much appreciated.

If you stripped the thermal grease you'll have to put fresh one on. Don't use the old bit. Beeping, short sequences or continuous can be all sort of issues. If it's not a jammed keyboard have a look at the computer's manual. Mother boards have specific beep sequences not unlike morse code that refer to specific faults. You just need to find that list in the docs. I had a mother board years ago (ASUS I think) , that had a voice recording. Sometime the PC wouldn't boot and I'd hear a muted chinese voice saying 'compoota feelur'. Worked out it was 'Computer failure' after a while

Leon,

Go here and select your BIOS and see the BEEP codes:

Thanks Guys you have been very helpful.

Well, after giving the computer a good slapping, pulling and pushing leads and applying thermal grease it seems that the problem is solved, well for the time being that is, fingers crossed.

Thanks to all for your assistance.

Check out clogged or dying (bearing worn out) fans too (especially if your motherboard's chipset needs a cooling fan on its Northbridge chipset).

My worry with dying fans isn't primarily either the rattle or the lack of cooling; it's that if the fan slows down or gets stuck at just the wrong point and you have any capacitance in your circuit you might send a very large voltage across your system. I've only seen this once and I don't wish to ever see it again. A moving coil in a magnetic field is an inductor, an inductor with some resistance as the cooper wire is good but not a perfect conductor. Now loop the right sized resistor, inductor and capacitor in series and you have a starter - like those that trigger neon lights. They can step up twelve volts to over a thousand for a brief moment if an alternating current flows through them.

Dying (not lightly, dust impaired) fans should be discarded and replaced immediately. So far I've had about 3 in 30 die in 15 years. One caused a short like I've never seen before - fried a lot of gear!

You will get beep codes if the fans stop but if it overheats it will just shut down.

Thanks for your interest and suggestions, it is all running like it was and seems fine now, however i might look into the fan suggestion that Matt put forward.
