Emachines w3507 power

detarch all accessories or hardware connected to the system , then bring out the power pack itself out completely look for a soldering led to test the functionality of the power pack itself if it rotates the fan of its pack by looping the first hole to the third hole cable in the power pack connector that will head into the motherboard. therefore, check the mother board if there is any damage on it like some component if all this is false . then plug the power pack to the outlet and fix the connector of the power pack to the motherboard after detaching both cd drive , floopy disk drive leaving the hard disk and the memory . then change the memory card and press on the system there should be a solution from all this . the problem should be from the Memory not to be able to start up the system but go through those process i have given you before concluding it was the memory ok....

kindly rate this solution......

When i press the on switch the computer light turn red color and have a beep sound.

1 or 2 beeps is normal when turning on, for most mobo's. Check the motherboard owners manual for beep errors, for example 3 beeps might be a graphics card error, 4 keyboard error, or CPU or memory. it's in the manual for the specific motherboard. You can get it from the manufacturer's website. I can not supply a link to get you the online manual because you didn't specify what kind of motherboard you are using. Does it still boot? Do you see the BIOS on screen? Any error messages? When you press the power button your computer normally should beep once or twice and then performs a POST... Power-On-Self-Test. and this is when you get any error beeps. It could be something simple like forgot to hook up the monitor, to CPU or memory is loose, or memory is not compatible if you upgraded the memory.

Where exactly is the fuse on a emachine t3958

The fuse on the power supply would be on the primary side (before the transformer). It's usually either under the cover, or it's in the red voltage selector switch.

But...if you have some lights on the motherboard, it's not the fuse. The power supply has to send out a couple different voltages (usually +/- 5V, and +/- 12V). If parts of the computer have power, then you probably are missing one of the voltages. You could get a voltmeter and check each one, but chances are you will just need to replace the power supply.

Tower problems

You may need to replace the cmos battery, its a cr2032 3v button cell
Make sure all your expansion cards and memory are reseated.
Make sure all cables are reseated.
your power supply could be bad

If that doesn't work try this

Here is my fix for the dell dimension 4400 amber light problem. It works!
replace cmos battery.
then unplug power cord form wall about 5-10 secs.
then plug it back in, wait 5 secs.
If amber light comes on, press and hold power button until it goes out.

(with light out, press and hold power button while amber light comes on and goes off again holding power button 2-3 secs after light goes out.) repeat whats in parenthesis until computer turns on
it should only take about 6, 7 tries.

After the computer boots, you may want to setup cmos or boot into windows.
After you shutdown, unplug power cord for 5-10 secs then plug it back in.
Press and hold the power button, computer should come on.
I found that's the only way to turn on the computer.
If you shutdown and don't unplug power cord the computer may not boot, mine didn't.
Strange I'd say

450 power supply

The cd may be bad, or if the power supply is just marginal, it may be failing when the cd motor spins up.
