Flashing screen

[ShivP]

Hi all

Odd issue on a PC. It is a Haswell based i5, with a GTX 660 running 2 screens.
Both screens flash i.e. go black then come back again every few minutes. I have tried plugging one into iGPU and one into the 660, and they still do it. Not really sure what to do next.
Any ideas?

Thanks

Drivers up to date , When did this start happening , does it black screen just one monitor connected ?

I would change both Hdmi cables

Are the screens known to be good on a different PC?

Is the PC known to be good on a different screen?

Has the power delivery to either or both screens changed recently? Are they plugged into the same extension cord/socket?

Have you tried any troubleshooting other than using the iGPU thus far please?

Anything in the event viewer?

Do you have any monitoring or accessibility software installed?

After all that turned out to be faulty power cable for the screen
Sorted now at least, thanks for all the help!
