as this is my first post, I'll try to explain my problem as good as possible.
At the moment the official windows 7 build 7100 evaluation copy is running on my system (dell inspiron 6400, dual core 1,83 GHz, 2gb RAM, intel 945 chipset). It's installed since april 2009 and didn't give me problems until a few weeks.
I've included several screenshots of Process Explorer to visualize my problem.
When I boot my system 2 svchost.exe's generate a high amount of CPU-usage (see image1) during the first minutes.
When I play some mp3s (with WMP or xmplay) at that moment, I can hear a lot of crackling and my systems gets more and more unresponsive. In Process Explorer, you can see even more (5-6) svchost.exe's generate high CPU-usage). Pressing pause on the mp3player gives me back the response and immediately stops the high CPU-usage of the other svchost.exe's.
But the two initial svchost.exe's keep generating high CPU untill after a certain time, they drop to 0% cpu.
After those initial minutes, I can do everything I want again.
Playing mp3s gives no more problems. No crackling, but clear sound.
I installed the latest Sigmatel High Definition Audio Driver, but that didn't resolve the problem.
I also looked up 'svchost.exe' and 'sigmatel' on this forum, but couldn't find an anwser to my specific case.
I'm not a newbie in techworld, but after wasting hours and hours on this problem, I'm ready to call for help
Thanks in advance!
