Try a different monitor /TV

How is the monitor connected? VGA?

so i have tried my samsung led tv & the pixel's are still flickering in that also so my monitor is ok.. do you think its the hdmi cable faulty?? or some other issue in this??

Hmmmmm...only one way to tell and that would be by trying a different HDMI cable.

Also use ddu uninstaller to remove all graphics drivers and reinstall the latest driver from amd.com

Eventually update the bios of your motherboard

Lower memclock. It is too easily powered to loose p-states at the 2000 Mhz part of the RX580. Artifacts due to excess power , RAM missing their clock cues. I think they also made a gimmick for this. AMD cool down or something orother. Which just causes the clock to stabilize by hanging until the excesses are gone and the 8Gb Memory wouldn't fry the card. changing the Maximum memory frequency of the card in the GPUs VBIOS to 2000 or 1750 should help.

It is high voltage power, which is necessary to power the chip, and the highest memory clocks sothey can be fast, and also not diverge tiimings and cause hanging, artifacts or a dead card
