Video card unseated or trashed/no fan running ? Also an unearthed large electric machine running near PC could cause it.

Speakers too close to the monitor can also cause problems, although I'm not sure they can cause such major problems.

Also fluorescent lights cause interference...the one over my workspace causes the monitor to flicker.

 

This probably isn't the problem but I thought I'd post it just in case. My cellphone will drive my monitor absolutely nuts if it's placed within a couple feet of the monitor. It acts as you described. Every so often the monitor will freak out. This drove me nuts trying to figure out what the problem was until the cellphone happened to ring when it was sitting close by. Didnt' take long to figure out what it was after the scene that created.

 

what should i do...

i think is it problem also cause from cpu ,,i think my be it's dirty and have need cleaning and other thing what can i do resolve this issue any possiblity to proper it...what i can do to monitor,,
Video card unseated or trashed/no fan running u mean which fan .......ether cpu or vg card fan....

z4u, I would take your PC to an authorised ASUS dealer with
engineering staff. Failing that a reliable PC specialist company.
Ask them to check that all components are being cooled
sufficiently and if not, replace cooling fans.
Fans are pretty cheap so it doesn't really pay you to try and
fix them yourself.
