I have amber light on my lan card on my PC?

Specs: Windows XP, DDR 400
I have amber light on my lan card on my PC? My computer won't run it is just this light and the chipset is heating. No power supply is running no processor nothing except this orange light on the lan card and the 5 volts chipset because i have PC - motherboard Soltek SL-K8AN2-GR with AMD Athlon 64 2800+, 1 GB DDR 400, chipset nVidia 3 250 GB ... A few days ago i saw that the conductors amount the processor are corrupted i bought new one and i will change them but i wanna know about this indication and why the hell the chipset is heating with no power supply running.

The lan card is running off the standby part of the power supply. The card has to running if WOL is enabled. The yellow indicator show that the lan is working.

If you don't know English well, you could use a free online translator.
e.g. this one seems to be pretty good:

"A few days ago i saw that the conductors amount the processor are corrupted..."

I searched the web using: SL-K8AN2-GR capacitor
and found several "hits" where they suspected there were failing capacitors on the motherboard.

If you have not changed anything inside the computer case, e.g. the ram, just before your present problem, then the most likely things are either the power supply is failing, or you have this problem.
If you do have this problem, you need to replace all capacitors that have the same brand name markings, because any of them may develop the same problem. Most people and repair technicians don't bother to do that and just buy a used motherboard that is not the same model that the same cpu and ram will work with, or they buy another system.

Some mboards develop this problem - electrolytic capacitors were installed on them that were not properly made, and they fail eventually - the mboard manufacturer didn't know they were improperly made at the time the mboard was made.

Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .

This was the original bad capacitor problem - has some example pictures.
History of why the exploding capacitors and which mboard makers were affected:

Thank for the reply and the helpful information about the motherboard infrastructure.
But i am not so worried about that i saw it i will change it.
I am worried about if there is another problem that cause this indication of the lan card and chipset heating. I have searched a lot in the net what means this but no success. I know that this capacitors or whatever could burn a lot of sets and if this indication is telling me something i want to know do i have to change them any way if it doesn't work. There is no smell of smoke or burned but still why the card and the chipset are working that way.

All modern PC computers have ATX specification motherboards. They are are always powered in some places, even when the computer is not running, as long as the ATX specification power supply is connected to them and the power supply has live AC power. The power supply is supplying power to the motherboard in that situation even when it's fan is not spinning,

There is at least one led on the motherboard surface inside the case that indicates the power supply is powering the motherboard even when the computer is not running in that situation - it's there to remind you that you need to remove the AC power to the computer when you are going to be plugging in or unplugging wiring or ram or cards that connect to the motherboard to avoid possibly damaging the motherboard or the ram or the cards.

The led for the network adapter lights up after the power button has been pressed, if there is a good network cable connection between it and whatever it is plugged into.

The led on the mboard and the network adapter led often light up even when the motherboard cannot boot normally, or even when the power supply is defective.

The cpu may get warm after the power button has been pressed when the computer will not boot normally - that is normal.
It's NOT normal for the cpu fan to NOT spin, or for the hard drive to NOT spin, after the power button has been pressed

The fan on the power supply does not spin until slightly after after the power button has been pressed, and that only happens if the mboard has sent a "power good" signal to the power supply through one of the wires in the 20 or 24 pin main connector's wiring to the power supply.
If there is something wrong with the motherboard, or if there is something wrong with the power supply, or if there is a poor connection of the main wiring connector from the power supply to the motherboard socket which isn't likely, the "power good" signal may NOT be sent to the power supply shortly after you press the power button, or it may be sent but the power supply can't respond to it, then the power supply fan does not spin, and the power supply does not fully power up the motherboard.

If you DO have defective capacitors on the mboard, eventually it's common for the motherboard to not "behave" normally while they're failing, e.g. the mboard may restart for no apparent reason, or when you select Shut Down in Windows it may restart instead of shutting off, and eventually the motherboard will not fully boot at all.

The capacitors fail very slowly, although they may explode eventually in the final stages. You usually do not notice any odor - smell - while they're failing.

Power supplies can develop the same bad capacitor problem.

Failing power supplies are common - they often partially work rather than being completely dead - leds may come on, fans and hard drives may spin, yet the power supply fan may not spin and the power supply will not make the motherboard boot fully.
You could try connecting a different known to be good power supply that you have, or someone you know has, that is in a working computer, but if you DO have failing capacitors on the motherboard, that may not be enough to allow your computer to wok normally.
You could also try connecting the power supply in this computer to another working computer to see if it will allow that other computer to work normally.

Thank you for the good and helpful information u gave me. Now i will try everything i have to to make sure that the computer will or won't live and when i do it i will tell you what is the result of my actions.
