Today i have run into a very annoying problem with my gtx 780. I rolled back my 780 driver in hopes that the previous driver would work with OBS and the new nvidia codec. After i rolled back it didn't so i decided to just re update to the saying "driver installation has fail driver i previously had (337.50). While trying to install the latest driver a message came uped". I have called EVGA customer support about the issue and did everything they asked me to do. I even tried to do a system restore but that failed also saying it couldn't restore one of the files. I have re seated the card and completely wiped the system of all nvidia drivers with treexy. Neither solutions worked. I have also tried to install the driver through device manager but to no avail as it comes up with the same error. Please help me. Your help will be very appreciated.
