I've downloaded/installed an update for NVIDIA and video seems to have cleared up a lot of 'noise'.
I had been getting constant script errors in IE. The Windows website said to disable script debugging for IE and for "other" in the IE settings, Advanced tab. These were already checked so I decided to uncheck these and save the settings. I then went back into these and rechecked and resaved. So far, no more script errors in IE. However, I am still getting the 'Can't find script engine "VBScript"'. Would it be safe to restore this (tmp2AF6.vbs) file from a previous backup?
As for the unexpected system shutdowns, I've not resolved. These happen as if the machine is going into a normal sleepmode after being idle for an amount of time, although no settings are applied that would cause it. Any ideas are appreciated.
Thanks.
