It seems odd that both Comm ports would die at the same time. My guess is that there is a problem in the CMOS configuration. Without particulars on what generation CPU/MoBo and which BIOS, I can't give you details on where to look, but there should be a setting in your CMOS that can turn off (disable) each Comm port. You should also check the device manager to see if there are any hints or clues as to the problem. RIGHT-click on MY COMPUTER and select PROPERTIES then click the DEVICE MANAGER TAB and look for yellow triangles.
