Thanks to Steve, UPHILL3 & plainsman for your input, I think my main problem is only 8gb RAM, I will pump it up to 16 gb to see if that will help. Having the computer off for 2 yrs didn't help !!, I have been slowly updating various drivers using Driver Booster 8. Free version only allows 1 update per day !
My Scottish heritage thinks I shouldn't have to purchase 3rd party software to solve problems. !!
I am also a PPL holder from UK. and Microlite licence on Jabiru here in OZ, sadly terminated by finance.
