I have a new PC running XP Home with SP2 and all updates and 2 CD/DVD Drives (NEC DVD RW ND-2510A. and HL DT ST DVD ROM GDR8163B). Both these drives cause Windows to "Freeze" and I have to switch off the mains. This happens three quarters of the time I insert CDs or DVDs to read. Someone reported a similar problem with "Store-bought CDs" on 8163B and asked for help but the thread was closed and I can't find any solution. My problem happens with a variety of media. I installed SP2 immediately after purchase so I do not know if my problem existed before. Is there a known Windows XP SP2 problem? Please help!
