My computer shuts down about 3-5 times then reboots itself. I was told to blow out the dust, which I did. I was told that it could be my power supply. If it is my power supply, what do I do? Do I go out and buy another power supply? The computer does not shut down if I leave it on for a whole day. But it shuts down when it is being used. Can you help me. This problem I have had for a while now. Thanking you in advance.
I have the same problem. my computer keeps on shutting down every 4 to 5 seconds. by the time i finish this sentence, i am pretty sure it will shut down and i will have o start all over again. it's pretty annoying...

Hello when was the last time you cleaned out all the dust inside? there may be lots of dust on your processors heatsink and it is getting to hot obviously it will get hotter when you are using you pc and may shut down your pc otherwise get a new PSU (power supply unit ) they are quite cheap have a look on ebuyer.com or ebay ps, you could get some new paste on your processor so the heat is transfered better to your heatsink.

Re: Computer shuts down.
So i guess that the PSU is good. As i diagnose of what you have said, i digested a conclusion that when the computer shutdown when application run. there a problem conflicting the application to another application or such an application trigering the system to shutdown.
Some causes of this problem are:
The system is infected by known and unknown virus
The driver of the system are not properly installed
The application program committed an errors trigering the system to shutdown.
1. Scan you system with a potent anti virus
2. Remove the installed driver of the sytem and reinstall it after restarting
3. Unistall the application that causes shutdown problem and you can reinstall it after restarting.
4. remove newly installed hardware or install the correct driver of the hardware.

A computer that is shutting down as opposed to rebooting usually indicates a heat problem. The computer will shut itself down to prevent damage. If it will run long enough for you to log in and use it for a bit. You can download and run speedfan. It will give the temperatures from your computers sensors. Usually the only one we care about will be the CPU. If it's getting up around 75 C then you certainly have a heat issue. You will want to go to radio shack and get some "thermal compound" the best one is Arctic Silver 5. It's about $10. Service Manual for your laptop Once your at the heat sink remove it and either on the heat sink or on the cpu itself where you see some grey compound. If there isn't much there put about half a pinky nails worth of the paste on it in the center. It will heat up and spread out on its own.
Also if there is a lot of dust, use some canned air to blow it all out.
The laptop will need to be dismantled down to the motherboard level, use a can of compressed air attach straw and blow out all ports, heatsink and fan. It might be a good idea to remove both for closer inspection and several good blast of air for good measure, and check the thermal paste between the heatsink and processor ic has not dried out.
OK, the thing is, if the fan is not rotating at all, you will need to replace it. The problem related to the computer shutting down, is the fact that the CPU overheats, and then shuts down the computer to protect the system components.
SO, if the fan actually rotates, you will need to clean the fan from all the dust particles collected on it. If the fan does not rotate at all, you will need to replace the broken fan.
It is possible that your computer is overheating and is shutting down to prevent it from doing any harm to itself.
Make sure that all fans are clean, there must be no dust present as it hinders airflow!!!
Install as many fans as possible. Computer temps should be in the region of 30-40 degrees centigrade. To avoid CPU throttling, where the CPU slows down to prevent frying itself.
Please take the time to rate my expertise.
A common problem with all laptop is dust. Sounds like you have 5 years worth of dust stuck in there. You should get a can of compressed air and blow though every vent you can! You want to loosen the dust that's in there and possibly try to blow it out and/or get it closest to the vents.
After that you should take a vaacum cleaner and **** out all the dust you can!
Dust inhibits air flow, alot! Its the number 1 killer of old computers.
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.
Shut it down.
Remove the power-cord.
Buy a can of compressed air ($3 to $5).
Remove the side panel(s).
Hold the can of air vertically (do not tilt it),
and blow away the dust from everywhere: inside the power-supply,
between the "blades" on the heat-sink & fan on top of the CPU.
Replace the side panels.
Reconnect the power.
Start it up.
Right-mouse click on My Computer
Under "Startup and Recovery", click "Settings".
Click to disable "Reboot Automatically".
The next time that it crashes, what error-messages _stay_ on the screen?
The 5840 has a problem with dust getting on the heater element and turning itself off after 2 minutes running. HERE IS THE FIX. Unplug the unit from the AC outlet, Then using a can of dusting air ( the kind you use to clean a computer key board) aim the compressed air INTO the middle louver of the upper adjustable heater vent and blow out the dust that has gotten on the heater element. ( You are actually blowing into the unit, clearing off the lint/dust that has gotten on the backside of the heater element that you can not see without openning the entire case).You can see the front of the heater element inside the louvers, It's the shinny metal part that looks like a small radiator.It sits behind the middle louver. After blowing out the dust, shake the entire unit to allow the dust to settle to the bottom of the case. Using a vacum cleaner try to vacum out any dust from the LOWER FRONT intake. Once the dust has been blown OFF the heater element, the unit will work just as new and not shut itself down!
How much memory do you have installed in your
computer? It may need to be, increased, as this is likely to be the cause
of your computer freezing, rebooting, times out, or shutting down.
Hope this is of some help. Bud
