Power, but not loading

Problem is, once the pc is plugged in, it stays on and will not shut off.
While in addition, it does not load windows, it just seems like its stuck in
the power light is only on mode. It gives power to the cd drive, but even
when switching the power cords from the cd to the harddrive it still has no
effect. And its not like the screen even comes up asking for a hard drive.
There is no siginal to the screen at all. It just sits there with the fan
going and power light on. And remember I cant just hold in the power button
and it turn off. Is there anything I could look for to see if it is a hair
or dust? Would that cause it? Should I look for some specific? It had
been sitting in a basement for a few months. Could cold or perhaps dampness
effected it? Should I give up all hope of repairing it. Its not worth
putting more money into and I'm just seeing if I can restore it. Thanks in
advance.

I've seen these symptoms before and every time I've able to fix it by
replacing the motherboard. If you have a spare board laying around try
swaping with that one to see if it fixes it. There was one instance when I
cured this problem by draining the bios by leaving the battery out for a day
and then resetting the bios with a jumper, so you might want to try that
first.

How would I reset the bios with a jumper? Sorry, I'm not a hardware expert,
just software;)
 
First you would have to tell us what the mobo is.
Make and Model. Usually though, just taking the battery out for 5
minutes is enough.

First a jumper is a little piece of plastic with a piece of copper inside
that connects two pins together. Look on your hard drive near the cables
connecting to it for an example. Now look on the motherboard for jumpers,
they may be different colors than the hard drive ones but it doesn't matter.
If your board is recent there shouldn't be alot of them. Now look for small
writing under a jumper that says something about cmos, this will be the cmos
reset jumper. Take it off and turn on your computer, you may hear some
beeping, that is normal. Turn off the computer and then put the jumper back
on then turn the computer back on. If the board is not dead this should
reset the cmos to its default settings. If it still does not work take the
watch battery off your motherboard over night with the power cable
unplugged. Getting rid of all power to the cmos will also cause it reset
back to default settings.

Do not change or replace anything until you have collected
essential facts. You don't yet have necessary information.
For example, you are but wildly assuming voltage exists. You
don't know that. A power supply not outputting sufficient
voltage will make the things you saw act accordingly but not
provide sufficient voltage to let computer run. And if
voltage does not meet that requirement, then circuits will
keep the computer from running and keep power off circuit from
working.

Very first piece of information is the 3.5 digit volt
meter. They are so inexpensive and ubiquitous as to be even
sold in Radio Shack, Lowes, and Home Depot. Make voltage
measurements per the chart in this URL:
http://www.hardwaresite.net/faqpowersupply.html

Then report back. Even if voltage is within limits, where
in that limits is important. IOW provide the numbers; not
just say voltage is OK.

If you change something, then problem can get complex
exponentially. We know that there is probably only one
failure. If you start changing things without first some
basic facts, the the complication increases exponentially.
Keep it simple. First collect basic information.

Well after taking the battery out and the jumper and that didnt work, I
looked in the back of the computer and figured what the heck and flipped a
voltage switch to 115. What do you know it worked. I recently had friends
over and I believe thats how it happend because I wouldn't switch that for
no reason. Thank you everyone for your help.
