Well it's within 4% of 12V, so it's not that bad..

I've seen stability issues when voltages fluctuate though. The Abit BP6 dual socket 370 board was one of several infamous for voltage fluctuations due to incorrect components.

Watching for voltage changes isn't all that easy though, since the BIOS doesn't typically have a very high refresh rate on its display (typically only refreshing once per second). Using the i2c stuff in Linux and the sensors program you might get a better idea of what's going on.

The other thing to question is the accuracy of the sensors themselves - I doubt they're precisely calibrated or even particularly accurate once calibrated.

The best way to be sure of the voltages would be to use a reasonable (or even a cheapo 3 quid job) multimeter and check at the power connector on the motherboard.

Of course, it's much simpler to just swap out the PSU for another one and see if that cures your problems...
