A while ago i found one of these cheap at a store so i bought it cause i was building my own pc at the time and didnt have much cash left. And my problem is that while dvd's work great on it i get problems allmost every time i use a cd. Most often it doesnt even see that ive put in a cd at all, on some cd's it works tho, just not very often. Would really welcome any kinda help/sugestions to what the heck to do to get it to work
