Hi, I was wondering if anyone had any ideas on how to fix a problem I have been having - When booting up the computer sometimes when windows has started the screen refresh rate is clearly very low. When clicking on 'settings' and 'adapter' and looking for the refresh rate there is no option to change or view as usual. This happens about 50 % of the time when I start the system. Now i can either reboot which is annoying or I can go into Device Manager and refresh the 'Display adapter' This then brings up the options to change the refresh rate under settings and adapter as it should be and although it will be set to 'optimal' i can change it to 60Hz then change it back to 'optimal' then the refresh rate is fine. I've tried reinstalling all the drivers, tried various options in setting the refresh rate a bit lower, but still it boots with the lower rate.

Any advice would be welcome.
