Problem: computer won't turn on when pressing the POWER ON button in the front of chassis.

The color green light blinks continuously when I press the POWER ON button, with the interval of 2 seconds, there are no sounds coming from mobo, and the fans are not working also.

Processor: intel core 2 duo e6850
Ram: 4gb ddr2
Hard disk: 300gb + 500gb western digital
Mobo: intel dq35mp
Power supply: Real Power 550W - Cooler Master - Leading Provider of Computer Case, Cooler, Power Supply, Laptop Cooling, Gaming Peripherals

Nvm, the technician tested the power supply on another computer, and its still not working..

I just bought a new power supply, now my computer is running.

Not bad for a 5 year old power supply. (warranty is only 3 years)

Tnx everyone!
