A while back, DVD-ROM drive did on my current PC. Replaced it w/ a DVD-Burner - been fine since.
Long time ago, I had 3 CD-Burner drives that were Phillips brand (Came w/ my old ass Compaq) and a Sony DVD-ROM drive die on me. After warranty died on that old thing, I bought Lite-On's CD-Burner and DVD-Rom - ain't had a problem since on that old thing, which still is up and running.
Pug, are you like running any games w/ nasty protections like StarForce? If so - crack 'em. Those bastards are known to destroy PC's.
I never heard anything nasty about Securom causing CD/DVD damage - except many feel it acts like a rootkey w/ the way it works.
