So I've had this problem for quite a while. If I have origin on and downloading something and I go in an app or game that consumes a lot of memory, origin would just freeze in the background without any notification and it seems like it's running fine but when you open it, it closes automatically. Then it relaunches and says "Only one instance of origin can run at a time" (Probably because of the Originwebservice which does not close with the app). I have a 6 GB RAM and I don't think anything else would cause origin to close itself because of low memory and I'm using Windows 10. Any help would be appreciated.. Thanks!

Are there any security programs running on your system? What happens when you run your system in a clean boot?
