Well, uninstalled graphics and audio and DPCs go to 100us (do you want etl file?)..

Installed again and all up to 1000us like before..

There is a problem with multimedia hardware and the rest of OS i see.., don't think faulty drivers but some VISTA problem..

All my drivers are updated (same drivers on 7 works ok)...

My e2180 IS a CONROE.., aka C2D. And it's running at 3GHz, oc'd. No matter what this app say...

Maybe is the USB port/sys? I see a lot of calls.. Or TCPIP.sys..?

Thanks.
