Does Safe Mode work OK each and every time ? Full system scan for threats OK ? Downloaded new graphics drivers ?
Safe mode works ever time and only once has system restore failed to work. Picking another restore point got over that difficulty. McAfee stills seems to be working so I'll try a full scan. Replacement video card fitted a few weeks ago so I'm assuming up to date drivers but will check..
I thinking of not renewing McAfee and relying on Windows built in stuff eg firewall, defender. I also have a program called Malbyte installed when first sent for repair. There is AVG as an option too
