My computer starts but after fiive seconds it makes a bzzzzt sound and then turns off
Is there anyway to save it of at least get files off it
Its been like this for a couple days
My friends said it could be the video card out of place or the huge pile of dust in the rectangle box thing

I really need help
I will try to get on later but I don't have a computer at my house anymore
Thanks for any help or explanation

If you need more information I will try to explain better

From your description, it sounds like it could be a power supply issue. Most likely, your files will be okay.

Here is what I would do, but please note that others may take issue with this procedure.

Since you say it is full of dust, you might disconnect it and take it outside. After removing the side panel, take a vacuum and suck the dust out from the bottom inside of the case. Do not touch any of the cards or anything else in there (just the case). Find the power supply (generally a squarish metal box) and on one side of the case will be the power supply fan (it is inside the case). Suck any dust out from the outside grille that you can.

Once it is fairly cleaned out, reverse your vacuum to blow and from a distance of 6-8 inches away, blow the dirt out from everywhere inside the case. Aim especially at the power supply fan that you just cleaned out. Once the inside is pretty clean, put the side panel back on and take it in the house. However, do not plug it in for at least an hour to allow all the remaining dust to settle.

If you're lucky, the computer will now work just fine once you hook all the cables back up. Otherwise, you can remove your hard drive and put it into an "external USB drive enclosure" that you can use with the new computer you'll have to get to get your files off it.

Best of luck!

Make sure that the cooling fan is working and yes, clean the dust out of it too.

Heat will cause it to shut down, hopefully before any serious damage can occur.

Good Luck.

Sometime time sound come out from Memory Card when put in wrong placing. Sometime CPU Fan is not running...

So you should open your casing and see your CPU Fan is running or not. If CPU Fan is running, switch off your power and check your Memory Card and VGA ( Graphic Card ) put properly or not .

It works again yay
After getting all the dust out I noticed that when I turn it on none of the fans were working
Dead bugs were jamming them
Thanks for help
