Is my GPU Core Voltage too low?

[kimmikkopls]

So recently overnight all of a sudden I had fps drop on all my games, I got 100-120 fps on Overwatch, 100-150 on CSGO, and 100-200 on League of Legends. Now I get 9 fps on Overwatch, 15 fps on CSGO, and 40-70 fps on League of Legends. I updated my drivers and reset bios but its all still the same. I found that my GPU Core Voltage was at 0.875 while gaming, I don't know the previous GPU Core Voltage but I believe this is the reason I have low fps.

Specs:
AMD Phenom(tm) II X6 1035T Processor 2.60 GHz
RAM - 8.00 GB
Geforce GTX 560

Please help! Thank you.

Is that the core voltage while gaming/GPU load?

In my experience, if your core voltage is too low you'll have crashes and artifacts, not low fps. And it shouldn't be an issue if you haven't been changing the voltage and/or frequency with an overclocking utility.

Yes this is while gaming, these are some stats while gaming :

What is the GPU temperature/frequency while gaming?

My Temps wont go above 40c, it is always at 33-39

What is the GPU frequency? It seems like the graphics card is throttling for some reason, what power supply do you have?

For the power supply I have a FSP Group Inc
DC output: 300W
Sorry but how do I check GPU frequency?

It's the "GPU Clock" speed listed in the stats you posted above (did I just miss this or do you keep editing your posts after I've replied?). It should be 800+ MHz, instead it's ~50 MHz.

It'd help if you posted your exact PSU model, but just based on the 300W rated output it's not enough for your rig. I don't know why your performance suddenly changed, or even if your PSU is for sure the cause, but just in general you should probably get a better PSU.

I edited them in right as you replied, my PSU model is " Model NO.:FSP300-60THA(1) ", but I'd been having this same exact PC for like a year and a half now with no problems.

Maybe it worked fine for a while but eventually one of two 12V rails on your PSU was compromised from overloading it. I don't know. Components degrade overtime, sometimes things work fine until one day they don't. Again, I don't know for sure if a PSU can fail in this way, and how it would present if it did, but replacing your PSU is the only idea I have.

I will try that when I have the money then, thank you.

Do you know someone who has a PC that you could try putting your GTX 560 into? Or even someone that might have a good PSU you could briefly borrow and try with your PC?

Sadly no
