Answer 1

The power suplly is the easiest thing to change on a computer.
Alittle common sense and it should be as simple as unplugging her to plug new in the same places.

If you think its the power supply, then go get one and good thing is if it isnt the power supply you can always return it.
But if it is the power supply you will save yourself diagnostic costs and the cost of repair plus the cost of the power supply.
So Im all for doing it yourself.

FIRST -- remove the power cord to behind your computer
SECOND -- open the computer
THIRD -- (heres the tricky part) will the new power supply fit into your system
But heres a way to get by just to check if it is a power supply problem
Get a power supply -- now theres really not too much to it.
Look at the connectors
Hold the new power supply in your hand as you disconnect each cable from the power supply.

Start with the (2) connections to the motherboard, one large one small

Youll have a tiny connection to the floppy

Then its a matter of your hard drive(s) and CD-DVD Drives.

Thats it

you could even just place the power supply connected (while your old power supply stays in its oroginal place, and turn the power button on --after youve plugged power to the new power supply.

If alls a go, you are good to go.
your next concern would be will the new power supply fit into your case? Or do you need to buy a new one.
Good thing is that cases are pretty cheap now. So ONLINE a new case and power supply combo could cost less then 50 bucks.

In store it will cost 50+ for just the case and another 50+ for the power supply.
But this little do it yourself attempt wil at least let you know if it is a power supply issue.

NOT AS HARD AS PEOPLE ARE MAKING IT SEEM.
ONCE YOU UNPLUG THE POWER CORD, your chances of doing damage are limited to how careful you are not to bang, bend any of the inner components.
Just do it all on a linoleum floor rather than a carpet
and always touch the metal case of the tower before proceeding towards the components.
This releases the static electricity that the human body naturally carries with it that could potentiallly damage computer components,.
BUT
doing it on a linoleum floor
Touching the metal part of case
and not banging anything

You will be fine
Try it for yourself..

If you can change spark plug wires then deifintely you can change a computers power supply

Additional advice: Don't turn it on anymore until you have replaced the power supply. If you continue to try to use it you can fry other components that it drives. I lost a hard drive that way and had to replace them both.

Answer 4

you need to open your computer up, and take the power supply out. If you are not experienced in doing this, dont!. Get a professional to see what the problem is.
