Post what your actual voltages are. Not sure what could cause them to be too
high... Too low would be underpowered but I doubt that's the case for
overpowered.
Are you using the correct hardware monitor program, properly set up
for your motherboard?
There is no "5VBat" on a PC motherboard, at least not a standard one
but who knows what an OEM did... there's a 3V battery, a 5VSB, -5V,
-12V, +3, +5, +12.
List your specific motherboard and power supply, make/model.
As for the 5VSB reading, has it always been the same, and is the PC
turning on and/or coming out of standby OK? If you have a voltage
meter it would help to take more accurate readings with it, from the
power supply connectors.
