My 2001 HP Pavilion xt936 suddenly failed to boot. When the power button is pressed the power suppy light(on the back) comes on, the power button light(on the front)comes on, the oragne light below the power button comes on for about 20-30 seconds, the processor fan comes on, the power supply fan comes on. Otherwise, the machine is quite dead. There are no beeps, the monitor does not come on, the hard drive does not activate. I have tried unplugging all the peripherals and swaping the monitor and cables all to no avail. The motherboard has no obvious signs of problems, i.e. no bulging capacitors or other damage. Does anyone have suggestions?
