I did do a clean install of 98se and I saw the garbled text after the cat 3.1's were installed (it happened no matter what install was used, as soon as it init'd the card text went screwy) The only other probably cause was the power supply, but the problem was there even before I slapped in an additional drive, and for the record, its a sparkle 350W supply, however connected to it are 4 hard drives, 2 optical drives, and of course video/mb. But I do not think the supply was the problem, besides the problem started out very minor and eventually became serious.
As I said before however, that 9500 is now returned to newegg.
