I have a 2 year old Area-51 R2.

Recently, my GTX 970, which came with the computer, has been acting really slow. I can't get more than 30 fps on less intensive games like Fortnite, even with minimum settings, and I struggle to get even 15 on Rainbow Six, also with minimum settings.

It looks like I'm completely up to date with all my drivers, and using the quick scan with the built in Support Assist tool says that my PC is completely optimized. However, I went under the Scan a Specific Piece of Hardware tab and scanned my GPU. After it did all its tests, the only thing that came out of it was a message that said that it failed. My CUDA core test and video stress test came out successful though.

I'm not very good with these things, so what does that mean? Is it time for an upgrade, or is this a driver issue, etc. Are there any possible fixes, or like said before, is it time for a replacement?

Any help would be appreciated, thanks.
