Well, with limited PC hardware knowledge, how comfortable are you with removing the RAM, and booting with RAM out? Use an ESD strap, or ground yourself prior to touchnig the PC. Also remove any power cords, and hold the POWER button in for 30 seconds prior to pulling the RAM. After booting with the RAM out, does it beep, or flash any lights? If not, then the MB has overheated and fried! The MB should be able to detect no RAM, and beep, or flash. No beeping, no flashing, no POST (Power On Self Test)!
