Programs Freezing When "Save As" Windows Appears

Hello, thanks for taking the time to read this and help me out.

Just a few weeks ago I started having this problem that I first noticed with Audacity. Whenever I would record some audio in Audacity and try to export it, the program would crash. I don't even get to name the file. As soon as the Save As window pulls up, the program crashes.

I thought this was just a problem with Audacity but I was working in Sony Vegas as well last night and the program would freeze if I tried to save my project. It froze in the same way, the window pulls up and then it crashes.

These are the only two programs I have this problem with but having them both come up at the same time leads me to believe that it isn't a problem with the programs themselves but instead with my computer.

Please reply soon,

Thanks so much for the reply!
I'm running the scan now so I'll get back to you on the results once it's done and I updated my system specs. Misunderstood that it wasn't asking for storage memory. 1TB of RAM would blow my mind. xD

Ran the program and it said it found a few corrupt files and repaired them. I rebooted the computer and tried again but nothing was fixed.

I had to run the scan in 'cmd' instead of 'command prompt' because command prompt wouldn't open up System32 even when I ran as Administrator. Could that have been a problem?

Just checked and none of the restore points are before the problem started. The earliest one is 8/7/2013. I tried checking 'Show More Restore Points' but that didn't seem to do anythings.

Alright, I'll be gone the next few days so I will have to wait to try until then.

I booted in safe mode and tried to save a project file in Vegas, same issue. So does that prove it's a problem with Windows?
