Reinstall the latest driver for the GPU. Download them from here:

Also, what PSU are you using?

I download the latest driver from this site but nothing happened and my psu is a local brand, name is navotech 600w.

1) try reseating the graphics card

2) doublecheck the cable from your pc to the monitor.. could be poorly seated or a bad cable there...

if you still have the problem.. try running in safe mode and see if the problem still occurs
