[rakhimishra]

Hii Everyone,
My monitor is suddenly turned off and black screen is appeared and it specifically occured when i connected to internet.
I dont know whether its a hardware networking problem ?

Have you tried restarting? Try a different cable?

Most likely a coincidence with the internet. Check all cables (including the mains ones), they are the usual culprits.
