Game crashes about an hour or two in

Hey!

I have been getting this same crashing error for the past few days and it’s starting to get a little irritating. It happens around an hour or two of playing. I have never had problems with Overwatch in the two years that I’ve had it. If it helps, I recently had to get a new Windows 10 OS because my other one got corrupted and I also upgraded my RAM. The crashes have been happening ever since I got those fixes. Here’s the crash logshttps://pastebin.com/ur2U7gd8

Any help would be appreciated.
