+ 0 Votes Sounds like a bad mobo... Jerry M. Gartner Updated - 6 years ago If all other components work independently of the motherboard, the motherboard is definitely suspect. I've seen motherboards fail to reset after mis-configured over-clocking settings. Depending on the reason for failure, you can sometimes see electrolyte leakage on top of some of the capacitors - those are the cylindrical things soldered to the board. Verify all jumper settings and power connections on and to the board as well. Good luck. http://www.gartnerwebdev.com + 0 Votes Power Supply or Motherboard w2ktechman 6 years ago arethe most likely issue + 0 Votes Reseat the processor Langlier 6 years ago if you havent already. Also if you have a different proc you can use that would be the next step... I'm 80% certain your board or proc is toast. + 0 Votes BIOS Sue T 6 years ago Are you able to get into the BIOS? Does the computer make any sound at all when you turn it on, do you hear the hard drive spin up, etc.? Did you try a different monitor in case this one is bad?
