A disaster happened to my computers.

First my secondary computer died.

It's configuration:
Abit Motherboard (5 PCI, 1 AGP port)
Celeron 1GHz
640MB RAM (I know it's kind of weird)
ATI All in Wonder 16bit
9 GB Quantum Harddrive (extremely noisy)
Deluxe no name case (worth $99 back in 2000)
And it was bought in around July 2000

Here's the symptom:
When pushing the power button, nothing happens.

Diagnostic:
So I think it must either be the power supply or motherboard.
If the motherboard died, I would had no other options but to buy a new computer (don't have the patience to fix it). If the power supply die... well... I'm too lazy to figure that out, so eventually I decided to buy a new computer (seeing that it's about time, and I do have some spare money to spend).

That leads to # 2 problem.
