I have an HP Pavillion a6847c running Windows 7; dual core 2.6 GHZ Pentium processor E5300, 6 GB RAM, 60 GB SSD, using onboard VGA video. I'm having some odd ISSUES, which are totally baffling to me.
     1. I try to change the POWER settings; say to turn off the display after 5 hours of inactivity. As soon as make my selection, the drop down box immediately starts scrolling by itself, until it reaches "1 minute", and there it stays. The OS will not allow me to change this; display power off or how soon to sleep the computer is stuck at one minute.
    2. I open the  Task Manager, and try to scroll down to see the list of services. I get the scroll bar to the bottom of the list, but it won't stay there. It starts scrolling back up all by itself.
   3. The screen resolution cannot be changed. It is stuck at the native screen resolution.
The motherboard USES the Intel G33/31 Express Chipset Family. I've run the Intel Driver Update Utility, which says the driver is current. Has anyone ever experienced issues like this? Thanks in advance for any assistance.
My issues were caused by a defective mouse. Problem solved.Glad your FIXED up and thanx for posting back...
