Drive will no longer read burned cds


My question is probably pretty basic. Since I reformatted my harddrive, my Optiarc Ad-5530A will no longer read the burned cds it did before the format. Is there a quick fix for this? Do I need to reformat again? I have noticed other strange bits from the outset. . . IE no longer even opens, some problems installing programs . . .

I’m using Vista SP1.
