Major Voltage Problem

Well, I was running MBM5 and the voltages for the -12.00 was like -7.83 and the -5.00 was +0.43. The computer runs fine, I'm wondering what happened. The voltages were fine yesterday. I think the PSU may be going south, but its running cool. Any suggestions? Also, SiSoft SANDRA is reporting the same thing. I went into the BIOS and it doesn't show the -12 and -5 readings. the +3.3 is 3.47, +5 is 4.87, the +12.00 is 11.73, and the CPU Vcore is 1.65v. Aida32 does not report these voltages for some reason also.

Any help in resolving this would be greatly appreciated.

 
Luckily the negative voltages are seldom used and the 3.3 isn't far off spec (3.465 is high limit) and 12v is not out of spec either (low limit is 11.4), perhaps there is no problem.
. Have you checked them with a DVM? Also possible that the "health chip" is poorly soldered or otherwise malfunctioning.

Whats a DVM? I probably don't recognize the term, but if you tell me I'll probably remember what your talking about, lol. And whats a health chip?
 
Health chip is the IC (Integrated Circuit) that actually monitors all of the items (commonly called mobo health factors) you are talking about and is read by the BIOS and/or software which translates the data from the health chip into humanly readable values. Winbond W83781D is a commonly used one.
