I have a windows xp home edition computer with a 2.0ghz processor and 512mb of ram. Whenever I go to read a CD in either one of my CD drives my cpu goes up to 100% and ends up crashing a few programs while in the process, if my CPU doesnt go all the way up to 100% then the sound will just be distorted and mouse will move very slow and choppy. My first CD drive is a Lite-On LTN486S 48x Max and my other is a SAMSUNG CD-R/RW SW-252S. With my SAMSUNG when it burns my computer runs fine and CPU does not spike, sound and mouse are fine. This is my first post so please forgive me for any and all of my n00bishness.
