Upgraded computer from p3 as new dvr107d video was jumping. Have XP, Gigabyte P4 motherboard, 2.8E processor, nvidia GE MX 4000 graphics. Also CD writer plus and new 120gb hard drive. System now freezes when disk put in either drive. Faults not consistent, sometimes music cd will play, rarely do software disk read. Upgraded Nero to 9, latest firmware for dvr.

Can you take a screenshot of your system. Is there nothing in there which shows up with a yellow asterix?
