    Probably a bad motherboard. Check the capacitors I am pretty much 100% certain you will find at least one of them puffing out or cracked open.
  3. All of the capacitors are fine.. Thats why i dont know what else it could be..

    May still be the motherboard, power supply issue would do something similar. Does the fan actually spin? If not, the CPU could have burned out.
    Does the computer seem like it's turning on or at least trying to? Does the hard-drive spin up? All lights go on?

    You can try to reset the BIOS to defaults, either move the jumper over and back or unplug the computer from power and remove the CMOS battery from the motherboard for about 10 seconds.
  5. I've tried it all the screen stays black and nothing is showen like i said before
    the Fan runs really fast, all the capacitors are fine, Ram memory is Fine
    Although i havent tried to reset the Bios defaults but i cant cuz i cant see anything on the screen.

    Fan going fast is most often a motherboard issue. You don't have to see anything on the screen to reset the BIOS, just use the jumper on the motherboard or unplug the computer and pull out the CMOS battery for 15 seconds.

    May be the CPU is overheating or has already died if not the motherboard.
