Since the past two days the screen has started to flicker.It happens randomly.

I suspect the gfx card is at fault coz the screen does not flicker when using onboard VGA.I reinstalled the card . cleaned the board .checked the connections. The screen did not flicker for about a day..until now.

I was able to capture the flickering from my cell phone cam.Pls have a look

Should I rma the card . its only 2.5 months old.

Or something else could be at play here.

Although this was written for a different card, chances are it will solve your issue:

That is a GDDR3 Card, and should be clocked over 900MHz. If ram issues are plaguing the card, it truly is defective and should be RMA'ed.
