So i ve built my computer 4 years ago, a year ago i upgraded my graphics card and recently formatted and installed new 1tb hard drive. From the day i installed HDD, on powering up, the screen wouldn't fire up so i check motherboard and i see VGA light red. So i just thought that during HDD instalation, i had taken out the graphics card to get access to sata's i might not have put it right back in. So took it out blew some dust from it and put it back in. Now it works.

Now a month later, graphics drivers stop working and recover on their own more often as time goes by. Then again screen goes black and vga light red. So i take out graphics card, blow the dust off, install again. and it works. But on start up the screen does an unusual blink as if graphics card not working for a second and the everything normal.

Could anyone be able to help as to what causes this? I believe my specs are visible.
