First screen turns black for a few second & driver crashes , now suffering massive fps drops . is my gpu dying?

Hey folks , i'm trying to figure out the problem of my computer .

My pc was completely normal until the last 3 days , the first 2 days i appear mysterious driver crash - game crash - screen turns black for a few seconds quite constantly when i play video games . The weird thing is those 2 games that i play ( dota 2 - skyrim ) were entirely normal and they didn't have any problems before .

After spending some time to google i thought that maybe my gpu is overheating so i tried to use a brush to clean up the dust on my graphic card , then tried a few tests (furmark - gpu z ) but the maximum temperature when playing games is just around 65-78 celsius , which i believe is not hot enough to make problems

Updated driver , re-installed games , did some tweaks but nothing helps .

But today is different , those 2 games don't seem to crash anymore ( at least not yet ) , but instead the fps massively decreased . I was playing skyrim at 50-70 fps before but now it drops to a pathetic 20-40 fps at best and i don't know why . also lag spikes appear when i play dota 2 , things like those never happened before :/

My pc spec :
intel i3 2100
6gb ram ddr 3
gt 630

Is my gpu slowly dying folks ?

It's not dying, I don't think. Uninstall your video drivers completely, and install the latest drivers. (I know you updated, but sometimes a clean install helps.)
Then try again. If that doesn't help, be happy you're getting 20-40 on that card, as it's one of the lowest end cards available. (I had one myself a couple of years ago, and it was unbearable after a while.)

Your rig sounds like it is giving up the ghost slowly. It may be a little of everything.
