I downloaded and used Eraser, and since then I have had to bypass an error message every time I power on my laptop. It is on a black screen with white text, and mentions "TURBODSK 2.1" and how no (QDMA or ULTRA QDMA?) controllers are loaded. I have limited knowledge of computers and don't mean to fault the Eraser software but it is awfully coincidental. Could someone please provide any insight as to how I can fix this? I reinstalled Vista, which didn't help. Thank you very much.
