BIOS /Flash Update ?

     I have a XPS400 2.8GHz Dual Core Pentium D 3 G.B. DDR2 RAM 250GB H.D. ! My question is Iam still using the BIOS version that was installed at the factory BIOS ver A05 ! There is a updated version A07, I have never flashed a BIOS and it seems like a rather straight up install Iam aware that if you where to lose power in the middle of flashing the BIOS your options are not pretty ,! It could make a rather easy operation turn into a nighmare . All of my hardware is working fine . I also know with a nrew version of the BIOS you may have to update drivers on your H.W. ! Is it best to just leave it alonre since the PC is performing well ? I kidof gop by the "if it aint broke dont fix it " belief .
