Did you miss where I requested a maximized Disk Mgmt screenshot - so we can see all of the columns? You have a mess on your HD. I would back up my files and Clean Reinstall - Factory OEM Windows 7 to get it correct, this time correctly deleting all partitions during install.
If not move the data off of G and H to Delete those partitions in Disk Mgmt, then Extend C into the space. Partition or Volume - Delete
Partition or Volume - Extend
As I stated use Windows Updates to get the latest drivers via optional Updates. If after all of your Updates there are still drivers missing then find them on the Support Downloads webpage for your exact computer model.
The SM Bus controller is an element of your chipset, so you may have to install the chipset or browse from that device into the unzipped chipset to find the driver. The ethernet driver may also be in the chipset if it isn't listed separately in the downloads list.
But try Updates first.
I would uninstall and not use the HP Support Assistant bloatware which defeats the purpose of a Clean Reinstall - Factory OEM Windows 7
