Windows 2000 and ATX power suplies

When I first installed win2000 I, it did shut my computer down when I asked for it, and I had the hibernate option. After a while this stopped working and even after e fresh new installation I cannot get it back on. Someone knows anything about these problems?

see in your motherboard for the advanced powermanagement options, and play with the settings, but before doing that make sure that you don’t have a yellow marker in your system properties.

dont forget to check your bios settings! :8
