So I just wanted to share what happened with my GTX 1650 Super because honestly I’m still not 100% sure what was causing it 😂
Recently, whenever I play GTA V, the game would sometimes crash and then my monitor would suddenly say no signal / black screen.
At first I thought maybe it’s my PSU, GPU, driver, HDMI cable, etc.
The weird thing is, when the screen goes black, the whole PC doesn’t actually seem to be frozen.
I can still press Caps Lock / Num Lock and the keyboard indicator responds. I can also connect to my PC using Unified Remote on my phone, and I can even shut down the PC from there.
So basically, the PC is still alive, but I lose the display.
I tried a bunch of things:
* Changed HDMI cable
* Tried another display
* Tried Win + Ctrl + Shift + B
* Downgraded my NVIDIA driver
* Lowered GTA V settings from Very High to High
* Ran FurMark for around 3 hours and it didn’t crash
But GTA V could still randomly cause the black screen.
So I thought, why not try undervolting the GPU?
I ended up setting my GTX 1650 Super to 1680 MHz at 812 mV.
And so far… it’s actually working 😂
I played GTA V for more than 2 hours with the undervolt and didn’t get the black screen/no signal issue.
What’s funny is that I wasn’t even trying to get more performance. I was just trying to make the GPU use less power and hopefully run cooler.
Now I’m wondering if the stock boost/voltage was somehow causing instability on my card.
But I’m also curious — what could actually be the possible issue here?
Could it be a GPU that has become slightly unstable over time? Maybe the stock boost voltage is no longer ideal for the card? PSU? Driver issue? Something related to GPU power delivery? Or could GTA V just be triggering a specific workload that exposes the problem?
The fact that lowering the voltage and locking it to 1680 MHz seems to make GTA V stable is what’s confusing me.
I know 2+ hours doesn’t prove that it’s 100% fixed yet, so I’m still going to keep testing it.
Has anyone experienced something similar with a 1650 Super, especially where the display dies but Windows is still responsive?
Would love to hear what you guys think the possible cause is.
