Graphic card giving display sometimes and sometimes not


Dec 7, 2016
Hello guys , i need help for my graphic card is not giving display consistently

Motherboard : Gigabyte GA-H110M-DS 2 DDR 4
Processor : Intel i3-6100 @3.7 Ghz
RAM : 4 GB DDR 4
Power Supply: 350 Watts
Graphic Card : AMD Radeon HD-5670 ICeq series
LED : Samsung LED

Everything was working fine but couple days ago when i turned on my pc i had no display on my LED screen, the blue light was blinking but no display but the graphic card was working with light and fan working. After several attempts of plugging out and plugging in graphic card again it worked and when display was back there was no problem. But the next day same thing happened, there was no display. I tried running my PC on internal graphics with graphic card installed and it was working. Somehow my motherboard is not detecting the graphic card sometimes.

I already tried cleaning my pc and graphic card also tried uninstalling drivers and reinstalling and also tried updating bios. i dont know what else to do
Any solution?
