    At one part I see "rests" and at another I see "resets". Do you mean that it is turning itself off for a few moments, then turning back on, or do you mean that it is going to sleep a lot (little green light turns yellow/orange)?

Toshiba e 2040c power shut down and on itself frequently

Sounds like the graphics chips, or processor is overheating & shutting down. Check that the cooling fans are running & they are clean from dust, dirt, or hair. Check that the cooling vents/ports are also clean & not blocked.

How to reduce fan/revving sound of a somehow old desktop PC

Old (& sometimes new!) computers make annoying and disturbing ventilation sounds that the user can not take it anymore.
Most of the time, it's related to the dust that is 'collected' on the computer's internal components (static electricity and stuff). Cleaning out that dust will not only make your computer quieter, but also slightly better performing (as less dust means less heat, and less heat equals better performance).
I have seen some computers even not start up or barely sustaining a minute of power up before shutting down, because of much dust inside.

1. The whole operation will be done outdoors, as there will be much dust extracted.
2. This is what you will need:
- Domestic Air blower (cool air) or an compressed air duster compressed can;
- Clean piece of cloth;
- Your computer's case (of course).
3. This is what you should NOT use:
- Hair dryer or any hot air blower: the air blown should be cool;
- Paper tissue or some other fabric which leaves behind small particles.

Get your computer on the table, and open the case. Often, it's either a couple of screws or clamps away.
Let your computer rest upwards, vertically: the dust coming off wouldn't get back in easily.
If you're going to use a compressed air duster can, DON'T shake it before spraying: you will mix liquid with gas, and will ruin your computer. This is one of the reasons I prefer an air blower over the compressed cans (which also run out of pressure).
You might, at first, need to stay a little away from your computer, while blowing off the 'first coat' of dust. When no more dust is coming off, spray over the corners and hard-to-get areas, to clear what might remain there.
After doing that, you still have 2 important components to clean: the power supply and the processor. Both will hold an amazing amount of dust, so be careful not to choke :)!
Cleaning the power supply is straight forward: blow air through the vents, from both (or all) sides, until no dust seem to go off anymore. Don't worry if the internal fans start rotating with the air you're blowing: they won't get broken, but they will become clean.
As for the processor, if you're experienced enough, the best way to clean it is to take it apart. But DON'T do it if you don't know what you are doing!!!
The easy way to clean it is just blowing air on its heat sink and fan, until they're clean enough.
Should you choose to take it apart, take off the heat-sink/fan package. Leave the processor in its socket. Clean the heat sink with air blows and then with the cloth. Same thing with the fan. If you have thermal paste, you might as well clean the processor, but if not, don't bother taking it off. After they are clean, put back the heat-sink and the fan on top of the processor and lock them securely.
Close up the case of your computer, and you're done!
Your computer now should be more quiet than before, and as stated earlier, you might even notice a slight increase in its performance!

I would remove the bottom cover and clean the fan and radiator as a build up of fluff will reduce the cooling.

My denon pma 355 keeps going into standby,it has always done so when it gets very hot,it is now doing it much more frequently,sometimes after only 2-3 minutes use

You might want to get an understanding of why it gets so hot. It's not toaster. Repeated thermal stress wil eventually kill it.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

First try a little shot of WD40 on both sides of the silver shaft that the carrier slides on. If that doesn't do it you will have to get some on the carrier motor bearings located in the R. rear corner under the case.

I have a ACER 5735 . The laptop shuts down suddenly while its on and sometimes im not able to switch on the laptop and even if i switch on , then once again the power goes off immediately . What would be...


The reason for the sudden shut down of your computer is because of overheating of the 'case', where the CPU is mounted. Overheating can be due to dust accumulation on the heat sink, which prevents dissipation of heat. The possible solution to combat overheating issue is to keep the laptop dust free by cleaning out debris at the vents frequently. Note that a laptop has a much smaller cooling area in comparison with desktops and hence laptops tend to accumulate dust a lot quicker than desktops. This is because all the dust/debris, in the case of laptops, accumulate in the cooling fins.

Hope this information helps you.

Fan comes on frequently on hp computer. dust etc

If this is a desktop computer, did you clean out all the dust inside the computer? You can buy cans of compressed air at places like Staples. Make sure you blow the dust out of the power supply and cpu heat sink.

Computer reboots

Hi cool,

Is your Computer keeps on recycling from booting and never finish to load your OS?

As far as i know you got a problem with you CPU, your computer processor is overheating inside that's why it keeps your PC recycling it's power.

Try to go to the BIOS setup menu, and go to the cpu temperature and you will that your PC is heating up.

Hope it helps & give you an exact reason.
