Folding @ Home only revives bad work units


Jun 23, 2016
Hello everyone,
I have been leaving my PC to run while I'm away so it can do more folding, but one day I decided to do some exploring and check the log. To my glorious delight, it was what seemed to be an infinite loop of downloading, just beginning to start, and "ERROR: RECEIVED BAD WU".

As you can see, I'm using my GPU (GTX 950) to fold, and not my CPU because I'm on the stock cooler and It always runs at boiling (I'm getting a cooler soon to remedy that). I have folding at max power.
I've tried clean installing Nvidia's latest drivers and reinstalling the F@H software, but to no avail. What could be going wrong? There's no way it's bad luck, this doesn't happen on my dinosaur with a 9500 GT in it.
(sorry I put it in graphics cards, there's no section for folding in the software section.)
