when i switch on the power of my pc there is no motherboard light but the fans in the psu n the cpu spin for 3secs n stop n then start again n continue in this cycle.my pc was working fine until today.
1. BIOS is corrupted (common with overclockers). Clear your CMOS. Your motherboard manual should explain how.
2. The Reset- maybe power button is stuck or defective. Try removing the reset line and see if there is a change. Does this start to happen right after you turn on your power supply switch?
3. Mobo has gone south- might still be under warranty? If so, contact their tech support.
Others may have input and I'll post if you have no joy here and I think of something else.
i tried resetting the bios by removing the battery for more than 1 hour and it didnt work.
i even tried the cmos reset jumper which didnt work either.
the reset and power buttons seem fine
btw this all started when i tried playing timeshift trial in vista it gave a message about saving memory dump and then it just froze so i pushed the reset button and when the pc started i got the dual bios screen saying it failed to copy the bios and it just shut off and after that this cycle of restarting started.
i dont understand why the motherboard led doesnt light up.

Someone else may have another idea- but this is what I'm thinking.
But power to fan and no light sounds like a dead mobo.
