I've a had a guillemot isis for almost 6 years and no problem whatsoever. but one day the pc crashed and when i pushed reset the pc became unstable. i re-installed windows and then the sound card drivers. the system keeps on asking me to re install (or check the connection). so i tried changing the pci ports and the same problem. then i decided to change the mother board and the same problem. could it be a short circuit?
