so when i press the power button, it lights up, the fan kicks on, the LED for power is on. keyboard lights are not on, no display, what ive done so far, replaced ram 2 times, bought 2 new sticks, and tried every combination of them. replaced hard drive power cycled checked every connection to make sure they was seated properly. removed cmos battery (24 hours) to clear bios only thing i can think of is motherboard gone out?

i have bad news it is most likely a motherboard issue so you have to get it repaired or replaced i wish i had better news for you
