-12 Volt problem

My comuter started a problem with just shutting down and rebooting, MB5 says that all voltages are fine except the -12V it is around -3.84. So I thought bad power supply....wrong tried three that I had lying around and get the same result. any help will be apprecieated.

The drop in the -12volt is usually associated to the fans that on within your computer I believe. I don't know why you have that weird reading. MBM5 has had some issues with different motherboard like mine was reading my diodes backwards and I had to switch it with MBM5 to make it read correctly. Check MBM5 fort possible motherboard complications.


Hey my name is Dwight too!

I am having the same problem with my -12v and -5v. -12v is reading -6.93 in MBM5 and in bios. My -5v is reading a positive .49 in MBM5 and there is no way to see -5v in bios. I just put my system together a few days ago and have been running Prime95 for 2 days with no problems. I have a noname 300w PSU with the 3.3&5 at 150w. I seem to be having no problems but am worried I might down the road.

Update:

I figured out MDM was reading my -5v sensor wrong and now it reads right. I am still worried about my -12v because it reads the same in bios as it does in MBM. Do I even need to worry about -12v?
