If you are getting a loud crack and smoke, you are having an electrical short inside the system. This could be the battery or some other electrical component.

Regardless, STOP USING THE SYSTEM IMMEDIATELY!

Have the system inspected by a qualified technician and ensure that there is no fire or electrical hazard.

There could be a problem with the battery shorting out, which has resulted in at least 7 system fires during the sony battery recall. There also could be a broken or bad connection in the system that is grounding and arcing, again a fire hazard.

Why does My Dell Inspiron 531 computer keep turning off


There are several possible causes for this. Laptops are notorious for dust buildup and overheat issues. Take compressed air and blast out the vent areas. If you can push enough air through the vent leading to the CPU cooling fan, that may clear out dust clogging the fan, preventing proper CPU cooling.

The next possible issue is a threat.

Boot into safe mode - keep repeatidly pressing F8 key as soon as you power on - until a menu comes up. Using keyboard up/down arrow, select "Safe Mode" (with networking if available).

Next, install Malwarebytes (free version) and perform a full scan. Also scan using your current antivirus.

hope this helps,

Danny

Cpu fan running at full speed


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

http://www.kitchentablecomputers.com/static.php - rules



Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.



Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards

desktop or laptop computer fail to boot for a variety of reasons, but a fast, loud fan noise signifies that the system is suffering from overheating.


The problem, and the steps for troubleshooting it, is not unique to the Gateway Desktops.
When the internal temperature of the computer reaches too high a level, the system will shut down automatically to allow the heat to dissipate.


If you attempt to power up too soon, the machine will not boot properly.

To boot, you will need to correct the cause of the overheating, and keep the machine cool.


Blocked Vents


Although different in size, both desktop and laptop computers have air vents to help the fans keep air circulating around the hot internal components.


If these vents become blocked, by pushing a desktop too near a wall or using the laptop on a soft surface, the air supply your internal fans need to cool the system is cut off.


This blockage also traps the heat inside, allowing it to build to dangerous levels.

Keep the air vents on your computer free and clear to allow proper airflow.


Dirty Computer


Airborne particles, such as dust, lint and hair, can gather on the air vents and internal components over the course of time.


This accumulation of dirt not only provides a sort of "insulation" to the electronic components, preventing the heat they generate from dissipating normally, but it also clogs the fan and heat sink to prevent proper function.


Use canned air and damp, soft cloths to thoroughly remove any built-up debris from inside your computer.

Dried Thermal Paste


The heat sink sits atop the CPU chip to help dissipate the heat the component produces. Thermal paste is layered between the CPU and the heat sink to help draw the heat away from the chip for cooling.


Over time, the cooling properties of this paste decreases, and the substance becomes dry and flaky.

You can replace this paste to renew its cooling assistance by removing the old paste remnants with rubbing alcohol and adding a new layer.


Thermal paste is also known as thermal compound or thermal grease, and is available at most electronics stores.
Check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat

Thermal compound is a sticky paste that is placed directly onto the CPU.

http://www.hardwaresecrets.com/article/Thermal-Compound-Roundup-February-2012/1490

Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.



Hot Environment


When examining overheating causes, don't overlook the environment you use your computer in.

External heat sources, such as fireplaces or even rays of direct sunlight, can cause the internal temperatures of your computer to rise.


This causes your internal fan to run harder in an attempt to dissipate the combined heat before temperatures rise too high.

Move your computer away from external heat sources to encourage more effective cooling.


Hope this helps.

Clean advent 5611 fan


Laptops are notorious for overheating. The fan and cooling vents also get clogged easily. Even a 'clean' place has some dust in the air, and it is attracted by the fan and static. Canned air will take care of some of it. Opening the laptop is complicated and not for the weak of heart. When the laptop is running, you'll feel air movement. spray through that vent with the laptop turned off.

My Computer is loud, WHY?


Hi there Monica,

My name is Mike and I'll be helping you today.

The type of noise it is making is important.

Usually it is attributable to a data or power cable coming in to contact with a cooling fan. This usually occurs after the computer has been moved or repaired.

If this is the case, the fix is relatively easy. Open the unit and locate the source of the sound. Move the cable away from the fan. Then close the unit back up. That's it.

It may also be a hard drive that is nearing the end of it's operational life. Without more detail I can not say for sure what is causing the sound.

To be on the safe side, I would suggest making a backup of your crucial files and documents. Anything that can not replaced should be copied. Then if there is a drive failure, the results may still be tedious, but not catastrophic. Think of it as insurance. Replacing a hard drive is nothing compared to replacing the data it held.

I'm still leaning toward the fan/cable scenario, but without hearing the sound it's making, I can not positively identify it's source.


Best regards

Mike

Why does my laptop have a blue screen when I turn it on?


This screen is called the Blue screen of Death and is not a good error to have. This could be happening for a number of different reasons. Overheating, your laptop is getting too hot, it may need a service, to clean and remove dust that is preventing air to pass over the heat sinks,CPU cooler etc... As airflow is limited, your PC therefore is not cooled effectively. Another reason is that your hard drive and/or RAM modules are either not connected sufficiently or are faulty, or part thereof. Maybe your processor needs to be reinstalled. Or when your laptop is in use it is not allowed enough airflow, ideally it should be used in such a way that no surface obstructs it's air intake vents.
But it could come down to the actual information on the hard drive, ie virus infection or corruption of boot data. To test this one would boot up the laptop without a hard drive. If it POSTs and stays on a screen, boot disk missing, or some-thing to that effect then the hardware is fine or relatively fine. this would in turn mean that the hard drive has failed, or the information within is corrupted.

All the best, thumbs up!!!

Overheating is porblem, i have a laptop and when i play games or watch movies it will overheat and shuts down.I have 2gb ram and videocard is GeforceGo 7600.


Yes, overheating in laptops is a problem because they try to provide the same abilities as desktops but do not provide for the primary enemy of all computers. Heat. There are many aftermarket devices and cradles for laptops to assist in dissipating heat, most of which simply provide some kind of distance between the laptop and the surface it sits on so that heat will escape.
