This report is pretty much empty, what are we supposed to do with such few informations?

Please follow our submission template and guidelines and make a complete, valid bug report, with required info, precise description of the issue, precise steps to reproduce it, small and simple .blend and/or other files to do so if needed, etc.

I keep seeing a message in the console right after I open Blender. I can't seem to save or capture what the console says before automatically opening blender. Is there any way I could capture this message. The message went something like->: ad lib: Cannot find 44100 hz. found 48000 instead.

I have no idea what this means. I do know that this started occurring recently and also triggers when trying the latest 2.77 version as well as 2.78b (I have not tried any other versions on this system).
I also know that I tried blender on a second computer and it worked perfectly although it has completely different specs. My gut is telling me that this is a recent graphics driver problem but I can't say for sure. To describe the issue basically the program it self works slowly. Trying to highlight buttons with your mouse, move the camera, or perform any action in blender provides lag within the software equaling seconds in latency.

Buggy System info:
intel core i7-6700HQ 2.60GHz
NVIDIA GeForce GTX 970M
Intel(R) HD Graphics 530
16GB DDR3 Memory
1000GB HD

Working System Info:
Intel(R) Core(TM)2 Duo CPU E7300 @ 2.66GH
AMD Radeon R7 200 Series
4.00 GB
1000GB HD

As can be shown the graphics card is the only real difference between the systems. I am probably wrong but has there been a reoccurring issue with NVIDIA graphics cards and blender? Is there something I can install to help with this or an option in the preferences I can turn off?

That is not an issue, read this:

Like the it was said, concerning the warning in the console - it is harmless and it comes from the Audaspace library.
To make it not show anymore go to File > User Preferences > System. Find the Sound label on the left and under it the Sample Rate drop down menu. In your case, pick 48 kHz and press the Save User Settings button at the bottom.

That should make the Cannot find 44100 hz. found 48000 instead not show anymore. It's just a warning about not being able to use what is in the preferences.

Yeah, audio stuff is just a warning message. And no specific issue is known with NVidia cards currently, aside from all the usual mysterious issues some users have continuously with their GPUs. ;)

Can you please:

Give us your exact Blender, OS and GPU (including drivers) versions, as requested in the template!
Ensure both your OS and drivers are fully up-to-date (and use official GPU drivers, not those provided by windows or tablet/laptop maker).
Try to disable any running antivirus.
Try to re-download and re-install Blender.
Try the latest build from our buildbot.
Try to start Blender in factory settings (--factory-startup commandline option) (this will ensure whether this is a userpref or addon issue or not).
Try to tweak OGL settings in UserPreferences, System tab.
Try to tweak your GPU driver settings (e.g. try different values between 'performance' and 'quality' if you have such slider, etc.).
Attach as text file here the report generated by Help -> System Info (do not paste it directly in comment).
