Rending Device has Been Lost, and Crashing Everything

When i play Overwatch, I get the Rendering Device has been lost bug (Maybe every 3 hours or so). And i used to be able to just restart Overwatch. But now i cannot relaunch overwatch due to it saying i am already in Overwatch. The worst thing is that i cannot even control alt delete to bring up task manager to close it. I also cannot open anything at all giving the only solution being holding down the power button on my PC.
Is there anything i can do?

Have you checked this guide yet?

Yes. I do not have an AMD graphics card, nor a Ryzen GPU.
