Graphics Cards not being detected
I just installed my new GTX 770 from MSI a few days ago and today, while playing AC4. The game crashed and my computer restarted. I thought nothing of it at the time but when I logged back onto my user. I noticed my taskbar looked different so I went into the Screen Resolution Advanced settings and noticed under Graphics adapter it didn't say anything. Everything was blank. Even now when I look at Geforce Experience, it tells me it cannot optimize games and show me my specs and under GPU it is blank. I have already tried disabling onboard graphics and tried removing and reinstalling my graphics card. I have checked the PSU connectors(two eight pins) as well and they both seem fine. The graphics card starts up and it runs like it is connected properly but it is not being detected by my computer in anyway. I would very appreciative for any help here as I don't know what to do.
