i got this hardware monitor prog running at the mo, and it reckons i'm only getting -5v on the -12v rail, is that good or bad?

the other voltages look fine

that depends.... is anything f****** up on your computer? I think those sys diagnostic programs are alright but a lot of the time they might just be scare-mongering. You might want to pop into BIOS just to confirm a bit more accurately as well (god knows how those program's get their information, but if you can check it at a lower level it should be more reliable info).

Also whats the quality of your components? if your motherboard and power supply are relativly cheap i'd be a bit more concerned than if they were top of the line. can't hurt to make sure you know where all your product warranties are :p

my stuff is too old for warranties, i'll check in the bios at the next reboot

lol you got enough harddrives in there octal?! lol

Nah dont worry about it. Its just mis-reading your voltage lines. Check in bios hardware monitor, but tbh if nothing smells like burning or crashes its probably ok .
