I seem to have a problem with my motherboard. The MSI core center claims the voltage 3.3V to be too low. It usually starts alarming when its bellow 2.95 and lately it has gone down to 2.85 or even less. Ive heard that this voltage is one of the two possible PCI slots voltages which is either 3.3 or 5.0, depending on the PCI device. The other voltages or ok and within tolerance but the one that is supposed to be 3.3 is often too low. Does anyone have an idea what it may be caused by? Is it the motherboard or could that be the power supply? Can it damage my computer? Im actually not using any PCI devices except for the fire wire for my vide camera occasionally. Thank you for your advice..

It mite be your power supply. Try testing with a spare, preferably a 300W or larger..
