Graphic card probably burned

I was playing a heavy in RAM game, I was having a blast when eventually the screen showed some large white and pink pixels scattered around the screen and 2 seconds after the screen was black with no response. The game was running in the background so I turned the computer off and on, everything was fine but this time I decided to play other game, Sims 4, also heavy in RAM. I was building a house when the same thing happened. I did the same, off and on. I did it a lot of times but one day it was severe, there were lots of large black, pink and white pixels. When I turned the computer on the Main board intro and Windows 7 logo were affected with the exception of the animations (as you may know the Windows 7 logo softly moves). Did it actually burned or it was other thing? I find the animation not being affected to be unusual as a former laptop got the GPU burned, the screen was white with black letters and glitches.

Did it burn? It was a NVidia 640 with 7 years of service.

Try to use the on board GPU from your CPU if you have a Intel one. See if it happens in a game playing at lower settings. Maybe you're lucky and it's the RAM instead.
Otherwise, pull your GPU out blow on it, use another PCI-E slot even 2.0 and see if it happens again.

I have no on-board GPU, it's a Desktop Computer. It was definitely the graphics card. I did everything I could and I think it's too late now as it also affected everything else besides the games, I was just not sure if it was dead or a thing I could fix

If you have a good CPU it should also have the ability to support your monitor. There should be a blue DVI port on the motherboard and you can plug it then. Anyway if you have another GPU and it works, while the 640 is not at a huge temperature and the fans are spinning, it's probably dead, yes. Unless you can try another slot or another PC and see if it works.
Also, I've seen these kind of artifacts happen to me when I overclocked too hard. So it is possible to maybe downclock your GPU to a more stable condition until you can replace it. Just use some software that can do this, MSI afterburner, EVGA precision or whatever you have from your specific GPU.

I don't have a direct port for a monitor besides the Graphic Card one, the fans spin and it doesn't heat much. I don't think I overclocked it as I don't even know what that is, but even then I'm always careful about those things and I'm the only one who uses the computer.
I'll definitely check if it works on other computer. I'll update the tread when I do so.

Or like I said, use a OC or monitoring application. And set your clocks lower.
Overclock is adding power in those applications. So you'll remove power instead. And see if it still happens. Or just get a new GPU and don't bother your head with it. But if you actually don't want to or can't replace it, try downclocking. MSI Afterburner or EVGA precision are good applications. Just click where it shows +0 Mhz and put -50 -100 instead, or play with those values.
Even if it works with downclocking, your GPU is still almost dead, this is just a temporary solution.

I already got a new GPU. Thank you for the tip I may try it one day but for now I won't bother about that GPU plus I don't think it's worth battling the same thing over and over again. I take it has it is, burned. Once again thank you for your replies, these may come useful one day.
