I have an Acer Desktop dual Core PC. It has a dvd re writer but whenever I tried to read any cd or dvd the PC gets hangs. This problem is generating after a fresh installation of the PC with service pack 2 of windows xp hlp

Very strange.. only thing I can ask is have you installed any programs that autorun when you insert cd's

When you insert a disc in hold down the key for a while (this will stop windows from autorunning anything).. if problem still there then could be a part of windows that didn't install properly
