-3.5 VDC on the -5 VDC a problem?

[ziscwg]

On the system in my sig, I ran a program called the Hardware Doctor that came with my MB. It showed my -5 VDC at -3.5 VDC.

Everything seems to run OK with one exception. When I connected an internal card reader to an internal USB header, I got a BSOD. I thought it was just something with WinXP and such.


Could these two things be related?

p.s. When I put another PSU on the system, that -3.5 VDC was up to -5 VDC with the same test software.

99% of systems made in the past 5 years don't even use -5V. There's a very good chance that your power supply doesn't even have a -5V lead and that the reading done by the software is completely bogus.

Thanks for your help. I think I am going to go grab one of the small tester and see what all the voltages are. They are only $25 for a little piece of mind.

What power supply is it? Like jonny said it may not even have the -5v so the tester won't really help.

You could also check the reading in your BIOS as Hardware Doctor may just be wrong.

The BIOS isn't really any better as it pulls from the same chip.

The power supply is an Antec 430 W that came with my Sonata II case.

That power supply does not have a -5v.
