My friend has given me her laptop to look at because it was riddled with unwanted pop-ups, viruses and browser toolbars.
The laptpop is an HP Pavilion Notebook PC Model: G6-1195sa running Windows 7 64-bit Home Premium edition. It has an Intel i3 M370 processor running @ 2.40 GHz.and has 3GB memory and a 300 GB hard drive.
I have removed all the viruses, etc and installed Avast free anti-virus. I ran a boot time scan and it is now clean. However, the USB ports were not recognising devices (flash drive, mouse) that I plugged in. The USB ports have power as shown by the flash drive's light and thedevice show up in device manager after being plugged in, but they don't function.
I tried updating the drivers from HP.com and the chipset driver install (sp52791.exe) appeared to work, yet did nothing. So I tried running it with Administrator permissions - still nothing. So I uninstalled the existing USB drivers and tried to reinstall - nothing. I booted into safe mode and ran it again with Admin permission = nothing.
I went to Intel.com to download the motherboard drivers. The program doesn't run... asking for admin permission. I ran it with admin permissions and it errors, reporting that it should be run with admin permissions.
I'm now stuck. Can anyone help, please?
