Query: This software make my PC so unstable.

After installing this software, my PC was so unstable, First it sometimes shut down for some reason and automatically reboot.Finally it shut down and tried to reboot, but windows didn't run and shut down again. It repeated by itself nothing torepair.Fortunately, windows XP ran once, why it ran at that moment, it is very lucky. I removed the junck software and PC worksfine. It is definately the cause.Additionaly, Roxio URL does NOT include "Easy CD&DVD; Burning" for support.I recommend not to buy this one, or to change the name to "Easy CD& DVD burning with much confusion"
