I have this HP HDX18 laptop for almost 2.5 years now. It came with Vista 64 bit installed which was later upgraded to 7 Home premium. It worked fine until Jan 2012 when it started slowing down to nothing. I got it checked and cleaned by the tech support for HP(pccare247) and also updated the drivers for sound, display and BIOS. Now the system runs fine until any media played whether offline or online. After that it slows down to nothing and the sound becomes crackling and also with a delay and distortion.
The system slow down and the crackling sound does not come at the beginning and when it happens the CPU usage reaches 100% and stays above 90% until that multimedia is turned off. Also, the memory usage reaches 2.7 GB out of 8 GB and never comes below 2.16GB. What I noticed is as soon as I turn the WMPlayer off the CPU usage comes down all of a sudden to 15-20% and after sometime stays between 1-5% but the memory usage never comes down from 2.16, that is the minimum. Please help.
