Ok, I've been fussing with this all day, doing research, trouble shooting, restarting over and over, and I'm not sure what to try next. I'm NOT a very tech savvy person, so be clear, please.
I have an Asus laptop with an integrated Intel Graphics HD 4600 and a Nvidia Geforce GT 740m running Windows 8.1. These are cards that came with the computer when I bought it.
I've had the computer for a year, but I've only just now noticed that the computer is not switching to the Nvidia card while playing games. I noticed this specifically, and figured out that this was happening, while trying to play modded Skyrim, when a mod (ENBoost) showed that it was using the Intel card.
Here's a list of the things I've tried
- In the Nvidia Control Center, it was set to automatically switch between cards. This function obviously isn't working. I set it to use the Nvidia card, and applied. This was the only application that seemed to recognize the Nvidia working, but it still wasn't. DirectX Diagnostic Tool shows that it's still using the Intel card. I also tried to set the card to run for Skyrim specifically.
- In the settings of Skyrim, it only gives me the option to use the Intel card, and doesn't bring up the Nvidia
- If I disable the Intel card, and leave the Nvidia card enabled, it switches to the Microsoft Basic Display Adapter. I tried switching that off, but it wouldn't let me. At this point, I tried to open the Nvidia Control Panel, and it said there was no Nvidia connected. It seems the Intel card has to be enabled for it to recognize the Nvidia is there.
- I checked to see if the drivers were up to date. It said they were, but I reinstalled them anyway.
- I unistalled and reinstalled BOTH cards at separate time
I'm starting to think that maybe it's a hardware issue, but I'm very reluctant to send it in. I had an unpleasant 5-week long RMA with ASUS at the beginning of the summer where they ended up replacing my hard drive, processor, monitor, and other things (some of which weren't broken when I sent it in) and I'd rather not send it back.
