Mr.You,
Previous to your last kind reply.
I had already checked Ram,with Memtest86+.It showed lots of RED errors...I then tested each stick...all were OK!
Symptoms:
Crashes 2 or 3 times approx;5-25 minutes after loading TWS.Then will run ok untill the close !!On this g73jw.
This has been going on with diff;variations for 5 years...
The Tech support response ...Too many charts,decrease from 35 to 12...!
No difference.This has happened on 3 different laptops!...On a WIFI connection 6down,3up.
Thanks for your help.
