I am having a couple of problems and I don't know if they are related or each needs to dealt with separately.
I keep getting this message
"the external tool disk defragmentation GUI could not be found for os windows unknown major release service pack 0 professional x86 64-bit"

I have a lenovo ThinkPad laptop ...

The other message I get occurs when I try to open the camera when talking to someone for example on skype or facebook camera the message that comes up is "kernel security failure" and a blue screen... then the system restarts

Can anyone help me with this please.

With thanks,
