How do i open my pc to blow the dust out

Use a 1" paintbrush and a vacuum cleaner hose. Then use a compressed air can to clear the fins on the heatsink also with the suction. It is also better to remove the fan, clean the underside and then spray it with dry silicone spray.

The best way to clean dust from your PC fans and CPU cooler is to use compressed air. You can buy cans of compressed air from any electronics store or online. Before you start, make sure you turn off your PC and unplug it from the power source.

How to Clean Dust from PC Fans and CPU Cooler - LinkedIn

..

Make sure you check your power cord ends to ensure that they are not loose. The the end to the computer and the end to the outlet.
If this is not the issue, then open the case and check the amount of dust. If the CPU is covered in dusk your computer will overheat and then shut down. You can use a vacuum to get the dust out, but the best way is to blow the dust out with a can of air.

It could be something as simple as dust stuck in the drive mechanism. Try blowing out all the dust with compressd air first.
If this Doesnt work the drive has to be replaced!!!!!

Probably that is a result of sticky dust particles under the keys of your keyboard. Get your computer to a computer technician to open it up and blow and clean the dust off. The cleaning should be done using benzene

The pilot assembly probably has dust in it. With the unit off and cool, use a drinking straw and blow across the opening of where the pilot light flame lights. Do not blow directly into the pilot opening, as the dust will only become more lodged in the orfice. By blowing across the top of the opening, the moving air will 'vacuum' the dust up and out allowing a more staedy blue pilot light to engage the thermocouple. You may have to repeat this processa couple times depending on how much dust is in the opening. These OPD pilots are very sensitive.

1. Check by replacing the monitor if you have any standby.
2. Open the Back Cover and blow up the dust using blower and dont **** it. If possible use soft brush and remove hard dust and blow it, especially near the chipsets.
3. Try removing the memory and reinserting.
Now try closing and switch on.

Definitely check the power supply fan and the CPU fan for dust. Overheating could be the culprit, good luck.

Before you go through complete disassembly, you might want to just 'blow' the dust out. Its much easier, less prone to error, and achieves the same result; All you'll need is an air compressor with a spray nozzle attached, and a minimum 25-30lbs pressure.

Steps:
Turn off the computer, and unplug the power cord.

Remove any removable cover - memory, wifi/mini-pci, hard drive, and pull out the battery.

Place the laptop, closed, upside down on a table or work surface, and hold the end of the air compressor's spray nozzle first against the fan vents while spraying air into the laptop casing. (You should see a cloud of dust burst out)

If there are more fane vents(there usually are), blow out each one in turn.

Hold the nozzle four inches or so away from the memory access, and blow air into the casing. Do the same for hard drive panel, and any other open vent or panel.

Close the hdd, memory, and wifi panels, and any other open panel, turn the laptop upright and open the screen.

Holding the air nozzle a few inches(four-six) above the laptop, carefully spray the keyboard(too close, and you risk blowing out the rubber pads that lift the keys).

Finally, wait a few minutes for any condensation to evaporate, and you're ready to go.

if you know the ram, that looks like a ruler with about 4 to 5 inches length you need to clean its contact point with pencil eraser. you can blow the dust with a blower. to verify the problem temporarily, remove the video card then use the on board vga. if this does not boot that means the problem now is your memory card push the lock on both end to release then clean as i've stated from the abve.

I think your system may be heated check out your processors temperature, if it is very hot change your cpu fan.
