I disabled the NetBIOS, and I've tried different mouse/keyboards with USB connection... still no difference. I've made sure that my chipset and LAN drivers for my MOBO are up to date... the only thing I have NOT messed with is my BIOS... it just doesn't make sense that this would start happening out of no where due to BIOS... I'm using a version of BIOS that is a little over 2 years old now, and there haven't been any issues until a few days back. Here is a new ETL file... maybe you can see something different here. http://cid-c9365deeff3ffb21.office.live.com/self.aspx/New%20folder/DPC^_Interrupt.rar
