Ha! LOL, -12V at -6V, that's funny. If that was true your system would not be POSTing. 99% for sure it's just the mobo lying to you. Lots of them lie or go wonky.
Also, could be a sign of badcaps on the motherboard, so take a look.
PS's are also badcap-prone these days, but in this case I doubt that's the problem as it's got to be a detection error, not a PS-voltage-output error. BTW, if your PS is out of warranty, pop it open (usually 4 screws), but DON'T do that while it's plugged in (and wait 60s or hit the power button to drain the big caps first). I once touched a PS heatsink while it was on... not making that mistake again!
Plug the PS into a PS tester (I can bring one to a meeting but I can't lend it out, I use it nearly every day in my business) to find out what it really is putting out.
