That's understandable. I've seen some cases in the past where making changes to the page file settings can cause issues like this, so I just wanted to check and see if that might be what happened in this case.
When you have a chance would you mind sharing a DxDiag so we can take a look? For more information on how to pull one up check out the EA Help website. Once you have the file please attach it to this thread. Thanks!
