Question about HP Pavilion a706n PC Desktop

2 Answers

A coworker of mine was asking me about a recent problem he had when he was cleaning his computer components with a can of compressed air. He told me that he sprayed the cd rom drive out and in return his monitor became in his words distorted/blurrred could that method of cleaning the drive have led to his predicament? Is it possible that he could have damaged components in the cd rom drive? The type of computer he owns is unknown (it is a windows vista computer if that matters) so I just wrote in my own computer name.

Cleaning the CD Rom and having monitor issues are unrelated. Compressed air is a good way to clean out a PC but some get too close with the can and end up spraying propellent on the machine instead of air. It's possible he got the video card/component wet and this is causing the distortion. Assuming he didn't use the same method on the monitor, have him open up the box and let it dry to see if it helps his problem. He should also make sure all connections are secure. Best of luck.

I seems a little odd that that your affect him monitor, the only thing I can think of is if he was holding the compressed air can upside down he might have shorted something out, but that shouldn't be reflected in the display. Have him try unplugging and plugging his monitor back in at the computer and the monitor, maybe something else got jiggled.

How to maintain a healthy Desktop or Tower computer

A computer system is like a machine,if you use it everyday after a while it will need some maintenance in order for it to keep on working in a healthy manner. There are lots of things that can affect the healthy function of a computer, for example dust cause many computer to become too hot and the heat can shorten the lifespan of the computer components which are located inside of the computer case.In this writing i will teach you how to keep you computer healthy without spending much money. you should clean you computer at least every six ( 6 )months.The first step is to but a one ( 1 ) inch paint brush and a can of compress air, the second step is to remove the left side cover of the computer case your computer may already have lots of dust inside so you should it outside and use the paint brush to brush as many dust as possible out of the computer but be careful not to cause any component to move out of position. Then you will use the compress air to blow out the remaining dust from the computer, try to blow the the dust from the CPU fan and other system fans in the computer.Usually these fans trap a lot of dust over time and this cause the fan not to push the right amount of air to keep the system cool can cause some components to over heat. After you finish cleaning inside the computer you will put back the cover in the way you took it off. your next step is to remove the keyboard from the computer by unplugging it from the computer and use the brush and compress air to clean it.
The next step is to clean the monitor, there are several types of liquid monitor cleaner available in computer stores.For example PC Clean Advance Formula is use to clean monitors along with a lint free cloth spray the monitor cleaner on the lint free cloth and wipe the monitor carefully, make sure the monitor is turn off before you attempt to clean it.

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!

The yellow lightcomes on when i tun on the power

Where in the sky? You alien life forms come down here, and ask these questions. I swear for the life of me..........................


1) Steady Amber light indicates a Power problem.

2) Blinking amber indicates a problem with an installed device.

For number 1; do you have a KNOWN to be good, Compatible power supply; you can borrow for a test unit? Perhaps in a working computer?

Also, same as above; Power unplugged to computer, Anti-Static Precautions followed; clean the inside of the computer out, with a can, or two of compressed air for computers.

For number 2; did you recently upgrade any hardware components inside the computer?
Suggest you remove all Ram Memory module/s ('Stick'), and clean their gold plated contact pins with a pencil eraser.
Remove the eraser dust with air, reinstall.

For additional questions please post in a Comment.

How do I clean/take apart the Lasco tower fan, mine is working but extreamly dirty. Purchased 3 at WalMart and ; no paper work in boxes.

Easiest solution is going to be compressed air, not canned air for blowing out keyboards and computers, but compressed air from an air compressor. These fans are not designed to come apart for cleaning.. they're meant to be used a year, thrown away and you buy another one.

Having problem with computer was told had to be cleaned out as programs are coming up even though i don't need them when starting ip. Sometimes makes a weird winding noise need some help to try and fix...

First of all, buy a tin of compressed air "Kenair" is what i use. Take the side off, go outside and blow it out thoroughly. If its whining/making a strange noise its usually where the dust gets inside the fan bearings. The dust also acts as an insulator on the component and heats them up causing the computer to fail.

How about cleaning using compressed air( it looks like an aerosol paint can)? Cleaning using cotton buds will only clean the outer side of lens, compressed air in can will clean the inner side of the lens. its like cleaning you computer keyboard, ( actually compressed air in can are used to clean the keyboards). A 30psi pressure of clean air is enough to wipe the dirt out of dvd lenses.
