Question about HP Pavilion A520n (DW233A#ABA) PC Desktop

2 Answers

Computer will not boot up.

I accidently left my computer running for too long in a place where the cooling fan could not operate efficiently. Now I can't get the thing to boot up. The power supply seems to be fine, because lights and indicators still work. How big is my problem?

Fan runs flat out after power cut - HP p6769uk Pavilion desktop


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 Might have dried up thermal paste 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. It might be as simple as resetting cmos or physically unplugging the fan then plugging it back in. b> CMOS Reset Jumper b> Desktop computer motherboards often have jumpers for resetting the motherboard CMOS. If you made a mistake when changing the configuration of your motherboard in the setup utility and used the CMOS reset jumper to clear the change, your computer may not power on until you return the jumper to its original position.
Power Supply Failure b> If you are using a pre-built computer from a manufacturer, the most likely scenario is that the power supply has failed. Some computer power supplies are able to support 110 volt connections for the U.S. and 220 volt connections for other areas. Check the back of your computer's power supply and ensure that the switch points to the 110 volt marker. In addition, confirm that the power cable is seated firmly on the back of the computer and at the power outlet. If your computer still does not power on, call the manufacturer for assistance.
Typically, a computer fan will run off and on while the computer is being used to keep the internal parts of the computer cool. Without these fans, the hardware inside the computer will overheat. However, when a fan runs constantly, it is a sign of a potential hardware problem and should be addressed immediately.

Dust
The presence of too much dust inside a computer CPU (central processing unit The dirt on the internal components of the hard drive acts as insulation and will cause the temperature of the computer to increase, making the fan run constantly to compensate. If this occurs, the computer can overheat and damage delicate and important computer parts. Clean dust with a vacuum attachment or compressed air can---never blow on internal parts, as the moisture from your breath can cause corrosion and damage. b> Room Temperature b> Computers can become damaged if the room temperature or the area directly around the computer exceeds 90 degrees. If the computer is located next to a heater or other area where excessive heat is produced, this can cause the fans to run constantly. Move the computer into a cooler room or a spot with greater air circulation. Computer Temperature b> The internal temperature of the computer can also cause the fans to run all the time. This most often occurs when the processor or other computer hardware parts are overclocked, or modified to perform beyond its designed speed. Overclocking the computer processor makes it run faster, but it also causes it to run hot. Additional fans and cooling mechanisms are required to keep an overclocked computer cool. b> Blocked Vent b> If the vent to the computer is blocked, there is nowhere for the fan to send the hot air. The hot air is continually recirculated back inside the computer, which keeps the fans operating all the time. The only way to prevent this is to make sure there is at least 6 inches of clear space around a computer. Placing a computer inside a cabinet or desk will also cause the fan to run too much. Computers should be placed in an area that receives plenty of ventilation. b> Hope this helps

Computer keeps shuting down


Shuts down when? Right after you boot it up? Or does it run a while then shut down?
If it shuts down after it has run for a while then the computer is probably running hot. Either the CPU Fan is not working or the Thermal Paste has dried up or is too thin to keep the CPU Cool. To prove it is running hot, let the computer sit for a while then boot it up. Once it boots up use it until it shuts down and immediately try to boot it up. If it does not boot up that means it's running hot. But if you let it cool off then try booting up you will be successful.

What's your problem?tower fan is always running off and on


Your computer's Processor/CPU fan is set to run faster when it is hot and slower when it is cool. That is why it get's quiet and loud. A clean may reduce the noise, by removing the dust from the computer system the fans will be able to operate more efficiently and effectively meaning that they won't have to spin as fast.

Install fans in your chassis to provide your computer system with freash air, an exhaust fan is also an idea to push warm air out of the system. Generally the larger the fan the quieter it will be, as a large fan can spin at a slower rate to provide the same airflow of a smaller unit.

Remember that it is that fan over the CPU heatsink that is keeping your computer alive. Overtime they can wear, replacing the fan is an option.

Take care!

I am getting blue screen with error of partmgr.sys. i did clean boot, it was fine for a day but it happen again.


Check the size of Random Access Memory (RAM) in your computer. Its small size could be the reason for this problem as many of today's software need large amount of memory to operate in smooth manner. Additional RAM will also increase the efficiency of your computing particularly for gaming.
• Excessive use of computer or a malfunctioning cooling system can make computer/laptop overheated. Whenever system is heated, its efficiency will go down. BSOD is one possible consequence of over heated system. Keep fan of your computer in fully functional mode.
• Registry is the most vital part of Win 7. Corrupt registry is the biggest reason for BSOD in Win 7. One way is to clean registry manually but manual tricks could wreck your system completely if you are not a top notch computer expert. More appropriate way is to buy a good registry cleaner reginout and PC optimizer

Contact Apple via e-mail or phone call (you can most likely find both on the Apple website)
It will most likely cost you money, but they can give you an up-to-date operating system and get your computer back up and running in no time. Depending on how old the computer it is, it may be more cost-efficient to simply buy a new computer. Check prices on an updated operating system and on a new computer before buying.
Hope I helped!

That sounds like either a graphics problem or more likely a memory problem. Try taking out a couple sticks of RAM or leave just one in and try that.

My computer fan is running continuously, from the time it turns on. (even before booting in to windows xp) why does my hard drive fan kicks in all the time - its loud and annoying


The fans in most desktops do run whenever the unit is on. Only high end/ performance/ or self built systems usually have self adjustable fan speeds.

When the power on switch is pressed, computer powers up momentarily, then shuts down. Both power supply fans run for only an instant.


I've had the same problem with another computer..
The simple solution, instead of buying and installing a new internal fan is to place the computer on its side and put a small electric clip-on fan directly over the vent. Turn on the clip-on fan and then start the computer; the clip-on fan should generate more than enough cooling so that the computer doesn't overhead.

Two notes:
The clip-on fans usually have the clip on the back of the fan so you can clip it to a bed headboard or to a small pole or shelf; the fan is about six inches across, and they sell at Target, Wal-Mart, Amazon.com, etc., for anywhere from $15 to $25, but you can usually buy them at Big Lots or similar stores for about $5 and you can sometimes find them at the Dollar stores.

You can use a larger fan, but a larger fan will generate too much wind. You want to use an electric clip-on fan and not a battery operated fan because a battery operated fan won't generate enough wind/cooling.

And, if the problem ends up being more than simply a cooling problem, you can at least use the clip-on fan later.

Let me know if this works.

Toshiba 4010 is giving me a "warning, problem with the cooling system message" Machine gets real slow. How can I inhibit this message, I have it on a cooling pad?


The electrical components in a PC generate heat, and fans inside the PC help move the air to keep the components from getting too hot. Excess heat will cause the fans to run constantly, damage components, and limit the speed of the CPU. All of these problems with high power and high heat will cause applications to work slower than normal. One of the main functions of the BIOS is to monitor the temperature and adjust the operating conditions. While the sound of the fan running all the time can be annoying, it may the first clue that your PC is running as efficiently as possible. To help your PC as cool and as efficiently as possible, do one or more of the following corrective actions.
  1. Update the BIOS
  2. Keep air vents clear and clean
  3. Minimize disk operation
  4. Minimize CPU operations
  5. Check whether FAN is enabled in BIOS

Computer turns on, but does not boot to XP


Generally, fans are controlled by heat readings...something to check is the operating temperature that is shown in your BIOS when you boot up...(access your BIOS by tapping on the delete key, or F2 key while booting)..if it goes over 70C real quick then there is a CPU heat dissipation problem, which would cause the fan to run like this i think that it is more of an issue that your CPU died...has your machine taken any kind of hit or fall that might have loosened things?...or perhaps the heat sink compound between the heatsink and CPU failed.....
but it also could be a dead MB
