What parts of a typical motherboard uses the -5V?

I just replaced an old power supply with an Antec EA380, and the
-5V rose to -6.17V. Is it dangerous though the system became
a bit more stable?

It rose to a lower value???

Only if your system uses the oldest types of 16Kbit DRAM chips or has
an ISA, EISA, or VESA bus slot with a card plugged into it that uses
-5V for chip bias or an analog output. I doubt -5V is connected
anywhere in any contemporary motherboard; the newest ones that may
support it are some MSI or Supermicro oddball Pentium4 models with ISA
slots.

Rising low... :)

3.3 became defacto as die technology shifted smaller and efficiency
rose.

Ah, no, he's talking about the negative 5 volt supply (which has nothing
to do with the shift from +5V logic to 3.3V logic).
