Sync is greyed out and turned off; how do I correct

Hi Michael,

I would suggest you to ty disabling Windows Firewall and check if you are able to turn the setting on by following the steps:

• Search Windows Firewall using Cortana.
• Under Allow an app or feature through Windows Firewall click Turn Windows Firewall on or off.

You can also refer to the post of Arul_D by clicking this

Let us know how it goes.

 

Help with unstable system

latest update,
I have changed psu for xfx 750W and keeping to stock values and use on board graphics, the system seems stable , has been for several days. If I try to unleash, then Its prone to occasional crashing.
So next step was to put HD6950 in with CPU in stock setting.
System very unstable again. crashes after about 5 mins.
I have lots of fans , CPU temp ~35deg, HDD ~30deg,
HD6950 ~ 49deg
When system crashes, I dont get bSOD but a grey screen with thin black vertical lines. I then have to re-boot . I get back, Windows reports error with usual 124 error.
Could the CPU be an issue ?
Dont have another to test.
Any suggestions ?
Thank you
