Screen Freeze Please Help…

[justintime2001]

The screen on my desktop keeps freezing, mainly when watching Youtube video’s but also whilst in general use.
I am running windows 10 64 bit with an i7 5820 3.30 with 16Gb of ram on a Gigabyte X99 Mobo. So far I have swapped to a new Sky Router, Installed a new version of Windows 7 on a new hard drive removed all USB devices and run Windows memory test but still it happens

I am now thinking it must be hardware that’s the problem. Any suggestions what I should check first and how please? It started to happen every few hours but Its happening every few minutes now and I'm pulling out what little hair I have left.

May have found the answer

I have moved my office phone by a couple of feet and it appears to have cured the problem! ...............Hope I haven't spoken too soon though.
