anybody had problems with the media player in windows 7 not playing CD clearly??

the problem is that a few of my CDs will play but are very distorted when using my "new" laptop although most of the CDs i have do play OK,

NO problem with disc as it is a genuine version and it plays in 2 other laptops,PC and music system in car

called the engineer and have had the CD/DVD reader repaced, speakers and motherboard replaced but the problem remains

any Ideas how to solve this one??? over to you
