Question about Acer Aspire L100 PC Desktop

Computer power on, monitor and fan issues

Numerous issues after cleaning. I cleaned the dust from my computer, it started sometimes for about ten seconds before shutting down again. So I found out that I needed to apply heatsink compound.

I did, it boots maybe nine times out of ten. But when I press the power button it will not work. I have to unplug the power supply and plug it in quickly, otherwise the fans start slowly, and the rest stays idle. The three blue lights are completely off, even when the fans are going slowly, and the one in the middle keeps flickering. Please excuse my lack of knowledge in computer terminology.

There are also times when it will be working okay for about twenty minutes, then the monitor gets diagonal jagged blue black and white lines and I have to restart, which leads to the first issue.

I don't know if I put the fans in properly, I've searched the installation of fans, but there is nothing on how to do it for an Acer L100, mine has 2 fans, They seem to be working okay when it actually starts. I just don't know about the placement of the wiring. I have both fans facing out, but I'm not sure if there's a certain position other than that (i.e wire to the right, name of fan upright when the tower is standing on it's side) I've looked at other older computers to see if there's a certain position the fans have to be in, but I find nothing that's similar to my computer.

Why I cleaned it in the first place, is because the computer kept overheating and shutting down. I have been trying to render/save a video I've made in Sony Vegas 8, but I cannot publish it, because every time it reaches 60 percent, the computer overheats and crashes. It's not an issue of RAM, and I even have a table top fan blowing directly on it to help it cool down. The problem is so bad that I cannot run my computer in any temperature over regular room temperature.

I'm sorry if this has been solved elsewhere, and I thank you in advance if anyone can help.

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!

My monitor keeps shutting off on my desktop. Tower stays on, but sounds louder when monitor shuts off


It could be an overheating problem.
Be sure all cooling fans and heatsinks inside the unit are clean of dust. (coolers are usualy on the processor, video card, inside the power supply and sometimes on the case itself front and/or back)

The best way to get it clean is to use a vacuum cleaner that has the option to connect the hose on the air exhaust, blowing air. The second thing you need is a very soft paintbrush wipe gently the dust from main components. Be sure not to touch by hand or hit any components.

Hope it helped

Good luck

No video output upon restart.

So it sounds like it's heat-related. Does that video card use a cooling fan? Is the fan still working? Maybe the PC needs cleaning out, you might be amazed at the amount of dust that can build up inside the case.

If you're cleaning be careful not to dislodge anything, or create electrostatic zaps. Leave the power cord plugged in to provide an earth, but turn off the power point. A new 2-inch paintbrush is good for brushing dust out.

If the card has a fan it could be clogged with dust, or may have died altogether. Find someone who knows how to clean or replace it, if that is the case.
