i cannot boot up my machine when there are two hard drives connected to it. The master is a SATA Maxtor drive. Boots up nearly* fine when all alone in the box. If i connect an additional drive (either IDE or SATA), after pushing the power button the machine comes up for 1 second (leds go on, the cpu and power supply fans spin) and then just dies. it doesn't go as far as the POST beep. no matter how many times i try it won't boot up.
I'm not sure though if it's the motherboard or the power supply or something else.
*It actually happens sometimes when only the main HDD is plugged in. But after 2 or 3 attempts it boots up eventually.
Any help will be appreciated.
