You have a machine made by HP and HP is who to ask for this.
I have a HP Pavillion,AMD Phenom IIx4 910 processor with 8GB DDR3-SDRAM. I've had the system a little over 4 months and recently noticed a slowdown in performance.So in looking for an answer I disccovered the MS Windows Event Log. My Event ID is 351. When I utilized the event online help it referred me to a blog at http://blogs.technet.com/wincat/. In that blog, in a paragraph just before the pie chart the author describes a problem (which mirrors mine) with the USB Miniport driver. He also states that fortunately there was an update for the driver which solved the problem. I currently receive automatic updates from Microsoft but I still have the problem. WHERE IS THAT DRIVER? Please help!
