Loud fans and Shutting down

Sounds like it is getting too hot. Does it feel real hot when it shuts down? Is the fan and power supply working well and unobstructed so they get good air circulation?

check the freezer fan, also known as the evaporator fan motor.

If you say that fans gives out loud swirling sound, i can suggest you update your bios because it is the one responsible for minimizing the noiseand making the fans swirl.
Possible that system is shutting down because fans might be shutting down as well.
You can also try to blow out some air on the vents because that is usually where your fans are, this will help clean out fans.
Questions: Does your computer restarts when it shutsdown automatically? if it is there might be a bluescreen error going on and bluescreen can either be a problem with software or hardware. A lot of troubleshooting needs to be done to isolate. Do the first solution that i have given you then answer my questions for further troubleshooting

It could be overheating, and shutting itself down, to avoid heat-related damage.

Turn the computer off.
Disconnect the AC adapter.
Remove the battery.
Purchase a can of compressed air, and give your computer a "blow-job" -- shooting compressed air everywhere "inside" your laptop, to remove dust.

The dust is acting as an insulator, preventing your computer's fans from cooling itself.

Or, take your laptop to a qualified computer technician, for more trouble-shooting.

The receiver in the Samsung ht-wx70 system that I have runs fine until all of a sudden I hear a loud bang and it shuts off. If I touch the unit, it is burning hot. I took the fan out and it works when I attached it to a 9v battery. Is it the fan or another problem that I should be looking at.

Could me many things. Let's think. I installed an antivirus once that would get stuck scanning some file, the CPU-- the main processor in the latop-- would go to 100% and would get so hot that the fans would go crazy cooling it down. It could easily shut down if left on all day from heat.

Another laptop I had- I read on the support boards (it would get hot and the fans would be very loud) that the thermal last between the CPU fan and the CPU would degrade, causing the heat dissipation to decrease-- the heat of teh CPU was not being wicked away through the paste to the CPU fan. Boom- the laptops would shut down from too much heat.

Did you install any new software lately? If no, it could be a hardware problem like I mentioned above.

Third, a friend of mine had a gateway laptop that would get very hot-- he could hardly use it. It was a loose/faulty graphics card that would get very got, causing teh fans to go on, and then the computer to **** down.

Many of these hardware problems are tough to solve over email like this because you need technical knowledge. Further, most of these require the unit to be sent in to fix, really, especially in the case of laptops which are tougher even to get at than desktops.

Call the manufacturer, as they might be able to talk you through a fix or sending it in. Even if it costs $130 bucks, it's still not the 500-600 you need for a new computer...

Good luck!

a couple suggestions:

try starting in safe mode and see if it does it still. It could be that you have some background program like Windows update or that new Windows active search function, which spends copious amounts of processor time cataloging your entire computer. Some anti-virus programs will do the same and eat up processor time. I'd try shutting down as many of these background processes to see what (or what combination) is causing the problem.

If this doesn't work, you might have a bad connection with your heatsink, which would cause your computer to stay at or your fan might be going bad, causing it to get really loud.

I'm not going to go into the possibility of it being used on a lap or bed or carpet where the fan intake vent is getting blocked. I know you've eliminated this as a possibility. Right?

open the case, clean the fans and remove all dust from the comp. Also if u have oil the fans (special electonics oil)

check your cables. it may be in the way of the fan's fins. also clean your fan for dust.
