Yes you are right, i can replace all the caps, i was hoping for a more specific answer, maby we have a data east wizard in here, that can tell me more exact, where the problem is

Waouw. That C2 is a leaky bastard.
Allright, so C1,2,3,7 are known for my pins trouble.
Should i replace them with same values? Or any other suggestions?

As i read here, sound comes later becouse of these bad caps also. Not a sound board problem?

Quoted from mikat11:

Same uf value, higher voltage is ok for any of those 4 caps. For example C2 is 100uf 25 volt. A 100uf 35 volt will work fine. Low voltage due to bad caps is the problem here. On initial power up the voltage in the 5 volt circuit is very low, probably near 4 volts. After a couple minutes or so the bad cap will charge up to near 5 volts and the CPU will power up like it should,then the sound board shortly after. Most likely C2 is the root of the problem and the other 3 caps need replaced because they are old and its a good preventative maintenance.

Perfect answer, thanks alot guys. Will order these caps

Quoted from cfh:

Don't forget the 330mfd cap which is below the heat sink, but on the left side. this is *really* important to replace. It leaks too, and will leak on the high voltage power section, and short the board. i've actually seen them start on fire because of this. The other caps mentioned will just stop the game from running. The 330mfd cap juice can catch the game on fire!

Well that sounds risky with the fire. Do you have a pic of the location? Whitch cap it is?
