I just didn't have a different system, so I contacted Nvidia to check my card but they confirmed it wasn't faulty by checking my GPU-Z info... but if checking it in a different pc becomes too important, I have to go in the market & install the gpu in some repair shop, then install the drivers, and then install the games because he just won't have games already installed in his PC... and still not sure if they'd let me install a game just because I want to troubleshoot my GPU...

there's no problem with the gpu guys... and the psu is a corsair 450W which I've been using since a long time but it never had caused any problem like this before...what I'm thinking is... since my gpu(GTX1650) doesn't need external power connecter so it gets power from the motherboard directly but because the motherboard is old, it may not be able to deliver the required power...If I replace the motherboard, it may fix... but what do you think?

All the games, what's strange is the fact that I haven't found a single post on any forums of people having the same issue... It never happens when I'm not gaming not even the slightest...

I've been experiencing these annoying black squares on my screen while gaming since a while ago.. they randomly splash on the screen anywhere in any amounts... be it any game... looked on internet but nothing helps... There's literally no one having this exact same issue like me... Im sure this isnt artifacting or GPU's fault because artifacts mostly happen due to high gpu temperatures but my gpu runs below 45C..and given that my GPU is 100% fine because I contacted NVIDIA's Live support and they checked my GPU-Z info,clocks, & VRAM. they confirmed that GPU isnt faulty or bad.. Also I'd like to mention that I was using A DVI-D to VGA active adapter because I have an old LCD monitor which only has a VGA port, since that wasnt a recommended adapter, I switched to a DisplayPort to VGA adapter but it still is a problem... and I have no idea what or how to troubleshoot this problem... Please suggest all possible fixes and causes... PC SPECS :- i5 2500 3.0Ghz 4GB DDR3 RAM 1333Mhz GTX 1650 4GB VRAM CORSAIR 450W PSU ASROCK h61m-VS motherboard 2019-11-15 23-18-42.mp4
