I attempted to update my sound driver last night, and after installing, it first blue screen'd saying there was a driver conflict. After rebooting, I can log in but upon logging in, there is just a black screen and a mouse cursor. Safe mode works fine so I'm assuming it's not anything too serious, but instead of trying out dozens of fixes that Google gives out for a black screen error I'm hoping that someone might be aware of a more specific one.
For background purposes, when I first installed Windows I was rather lazy and instead of grabbing the most up-to-date drivers for my motherboard via the manufacture's website, I installed them from the disc that came with the motherboard instead. This worked fine, for the most part, but I began to notice that the onboard sound was rather unreliable. Occasionally it would just ignore the left speaker, even though the speakers themselves were in perfectly working order. I attempted to update the driver but the installation did not go correctly. Every time I started Windows it created a popup saying that the driver did not match the OS version.
To be honest, rather than fix it I simply either worked with the monitor's sound which was supported by my video card's HDMI connection, or if I wanted to use headphones, I would just use a plug-and-play USB audio jack. I ignored the sound driver issue.
However, recently the USB audio jack has been dying (it was eight dollars so I'm just happy it lasted this long), so I tried installing the onboard audio driver again. The first thing that happened was it did not install correctly. I received the message that it may have not installed correctly and that I could reinstall it with different settings. I did that. That installation was successful but then I ran into the problems mentioned in the first paragraph.
I attempted to do a system restore a day before I attempted the driver installation. It made me do a disc check first because it claimed my C: drive had errors. After doing that, it allowed me to do a system restore. That, unfortunately, did not fix anything. I could try doing it at an earlier date but I'd rather not do that unless I have to.
My motherboard is a BIOSTAR Group N68S3B. I downloaded the driver directly from BIOSTAR's website. My current video card is an MSI Radeon HD 7770. If there is any information necessary that I didn't provide I apologize.
EDIT: I've actually tried waiting it out, and after about five or so minutes everything starts up normally. I don't really understand what could be causing this.
