No power, power supply & motherboard green light blinking

I moved my computer to a new spot, and when I did I vacuumed off all the dust off the side of it.  When I plugged it in it will not power up.  The power supply has a green light on it and it blinks, the motherboard has a green light and it blinks as well.  It also has a ticking sound, kinda like a watch.  I have unplugged the power supply from everything inside and replugged it back in, took the ram out and put it back in, checked the battery and it is good.  Any ideas??  It was working fine up until I moved it.

    That is what I thought to, but I wasn't sure.  When I unplugged everything I plugged just the power supply in and the green light came on but did not blink, and there was no ticking sound.  ????  Could it still be the power supply?

    Drum error lights blinking, no paper fed tray 1 message, Blue go light off, and removing paper tray and toner cartridge doesn't help, nor does unplugging or sliding the green tab back and forth several times on the drum assembly. It prints blanks until the paper tray is empty.

I had the same exact problem for the same exact reason. Plug the power cable into the back. Open up the side of the case and unplug all the wires that the power supply plugs into. The motherboard, harddrive, cd & dvd drives, everything. wait about 10 minutes and plug them back in, plugging the BIG cable that connects to the motherboard back in LAST. This will make the light go from blinking to solid. I think it is a safety? to protect the motherboard from damage.

Plug your computer back in and turn it on if the power supply fan isn't working correctly, then that would be your ticking sound and also the computer will not turn all the way on if there is something wrong with any of your fans.

Btw, I’m available to help over the phone in case u need at

    Check your fan that is on the processor and make sure that it is working, if it is plug the hard drive in only and try it that way, if no ticking then turn off and plug cd rom in etc... keep this process and eventually you'll find that tick. and since the power supply doesn't tick then it's ok.

Power supply in HP slimline s7310n

It sounds like the CPU is over heating. It probably has poor ventilation. Unplug the unit and open the side panel. Carefully vacuum all the dust inside. Be careful not to damage any electronics. You can use a small brush to loosen the dust before vacuuming. Good luck!

How to Reduce the Noise of Your CPU Fan

The CPU fan is what keeps the processor of your computer cool while the machine is running. A noisy fan on the CPU can be very annoying for users of the computer. However, it can also be a sign of a dangerous problem in your system. If the CPU fan is making noise, it is probably not running at full capacity to cool the processor, which leaves your computer open to problems involving overheating of the processor. An overheated processor can be permanently damaged.
Step 1

Unplug the computer from the wall. Remove all devices from the back of the computer and move them away from the area where you will be working. Either wear an anti-static wristband or discharge any static by touching a metal part of the computer case.
Step 2

Remove the screws from the back of the computer case with a screwdriver. Pull the sides of the case off and set them aside. Lay the computer on its side so that you can easily see the motherboard and all parts connected to it. Locate the CPU fan; it will look similar to the image in the introduction.
Step 3

Ensure that no cables are hanging low and touching the blades of the CPU fan. Move any cables or other parts that could be hitting the blades of the fan causing noise. Tuck these cables and wires into an area where they cannot interfere with the CPU fan.
Step 4

Use a cotton swab to remove any dust that you can from the blades of the CPU fan. Don't use any harsh solvents or other cleaners that could drip down and damage the processor through the fan.
Step 5

Spray the compressed air into the fan to move the loose dust away from the processor fan. Move the dust into an empty section of the case with the canned air. Don't spray the air too hard or else you can spread the dust into other places in the computer.
Step 6

Use the vacuum cleaner to vacuum up the dust that you moved away from the CPU. Place a crevice tool or other attachment onto the hose to reduce the size of the opening and help ensure that you only remove dust.
Step 7

Replace the computer case. Plug the computer and all devices back in. Boot up the computer and check for reduced CPU fan noise.

Thousand white spots on screen started with two more every day can it be fixed ???????????????

Sine the TV's a rear projection DLP and the problem "grew" over time, perhaps those white spots are... DUST!!! Try a vacuum cleaner; there are ventilation holes/slots on the back and sides. If sucking and/or blow air into it moves the spots, then it's definitely dust or some other debris/contamination. If the contamination is hard to access, you may have to open it up to do liposuction.

Computer shuts down on its own

Most likely when a computer shuts down on its own it is because the computer processor or power supply is either overheating or is under powered.
Feel with your hand around the computer case and back of the power supply (has circular fan usually/ on off switch/ and a plug goes into it)
If it is very hot you will have found your answer.
Did you just install or upgrade a processor? If so you may need to check to make sure that there is thermal compound (artic silver, etc) between the processor and heat sync. This can cause overheating and sudden shut downs. If not move on
Is your computer in a small enclosed area? Try moving it to an area with more area for ventallation and cooling.
Do you have adequate cooling/fans? are they working? if not check power cables and may need to replace the fans or install more. You can buy and install case fans pretty easily
DUST. Are the fans and imputs dirty? Keeping them clean will keep the computer running cooler and help lower temperature and avoid shut downs. If your fans/imputs are dirty remove dust by using a can of compressed air, a vacuum made specifically for pc/electronics. or you may wipe them down with rubbing alcohol and a dust free cloth.
This should help Anthony

Following about an hour (hopefully) of run time, this computer shuts down (appears to be overheating)

Heat is cause for "random" shut downs.

While the computer is running - inspect the visible fans. Make sure they're running smoothly - a screeching fan is not spinning at the correct speed - and like those not spinning at all; isn't doing the job intended. Replace any fan that makes noise or does not spin freely or at all.

Shut off the PC and take note of plugs & jacks; and disconnect all cables.

Remove the computer to a table with ample room to work. Position the computer so that left removable side panel is facing up. Loosen (or remove if required) any screws, clips or other fastener used to secure the panel to the case. Remove the cover and set aside.

Using a crevice tool or narrow wand attachment on a vacuum cleaner, gently vacuum the inside of the computer case. Try not to touch any components inside. Gently move cables and wires out of the way to allow the vacuum to **** dirt, dust, etc. from the motherboard and interior of the case. Some plugs at the end of wires can very easily be pulled off of connectors to the motherboard, so be very careful moving the cables and wires out of the way.

Be sure to pay attention to any slots in the case or drives - such as a floppy disk. Vacuum dust from the the opposite direction they entered - pull it back out instead of pulling it all the way through. Check openings in the case designed for airflow. Clear any obstructions found. Inspect the power supply. Often, a fan blows outside air into the power supply - coating the insides with dust. The dust is often visible choking the slots of the power supply inside the case - this should be vacuumed away from the slots, to restore airflow.

Inspect the CPU fan. Remove any dust and dirt caught on the fan blades. Spin the fan by hand. It should spin freely. Shine a light through the fan to view the heat sink. the heat sink is just a large metal piece that sits between the fan and the CPU itself. It conducts the heat created by the CPU away from the CPU - where the fan blows comparably cooler across it, wicking the heat away. If the heat sink fins, posts, or channels are clogged or coated, the CPU fan should be removed and the heat sink vacuumed or bushed clean in place. The CPU fan usually held in place with 2 or 4 small screws. Remove them and the gently rock the fan from the heat sink. Move it just off to the side so that it won't need to be unplugged from the motherboard. Clean the heat sink and reassemble.

After removing as much dust as possible, reassemble the case and reconnect. The overheating problem should be resolved. If you're still having issues, you start over again but this time try blowing the dust out. A caveat of that is that it forces dust and dirt deeper still into components inside the case. If the computer is not working - this may not be a cause for concern. It would be best to use a "shop air" source - like those compressors found in workshops or gas stations as they have large the large volume of air at significantly high pressure. Canned air bought in stores can't come close on either of those two qualities - but is better than nothing.

Reassemble and try again. If it is a heat related problem that hasn't existed long enough to cause permanent damage, your PC should work fine once again. Please rate this reply "very helpful" and good luck!

I cleaned my motherboard (MS6577 ver4) by using a vacuum hose to **** out my VERY dusty my machine! However, after plugging back everything, it won't power on. I don't know why it wouldn't turn on since...

Assuming you didn't get the vacuum hose down by the board and accidentally break off or bend one of the components....
I have done the same thing before and the vacuum gets the easy dust that you can see however sometimes it will move the dust but not completely **** it up and it will cause a short on the motherboard. Best thing to do after using the vacuum is to get either a can of air or an air compressor of some kind to get the last bit of dust out that you can't see)

Eureka 2998az uno. Unable to remove dust cup.

The lever underneath the dust cup needs to be moved from the right side of the vacuum (viewing from the front) to the left side of the vacuum. The dust cup should then lift up and out for emptying. If the lever does not want to move all the way to the left it might be broken or jammed. If this is the case my suggestion would be to spray some WD40 into the lever area under the dust cup and try working the lever back and forth until it is freed.
Feel free to get back to me if you are still having trouble.

Acer Aspire T300 takes several hours for light on start up switch to come on and then the computer will then boot up okay. Have to keep the computer on all the time so that I don;t have to wait all this...

My first thought is that you are right. My second thought is that your computer is probably a couple of years old and some power supplies will wear out. Especially if there's a lot of dust bunnies running around. I'd first take a vacuum to it. Put the vacuum right on the fan of the power supply and let it spin it up, then move it to a spot opposite to that. If you can, remove the case side and vacuum inside as well. Get all the nooks and crannies, but be careful you don't knock anything loose. No guarantee it will help, but it just might.

Gray spots on screen on a JVC HDILA model HD 56G 787

The gray spots are caused by dust on your lens, very easy to clean.

Power down the TV.

If you open the right side access panel (right side as you are looking at the front of the TV) you can see it in the middle, it's not very big. Using a scratch/lint free cloth, gently wipe off the lens or use a vacuum to **** up the dust being careful not to actually touch the lens.

Replace the access panel and enjoy your spot free screen.
