There are dozens of complaints, maybe hundreds, of Microsoft PC users having issues seeing search results within Google. There are several threads but here is the largest Google Web Search Help thread with complaints.
It seems it is happening on several browsers that are on Microsoft machines. In short, Google is showing the user the number of search results found but it then hides the actual search results.
Google tried to push out several fixes yesterday but the bug is still an issue for many.
It seems that the only way these users can get it working is by disabling the "Instant Predictions" and then the search results show up.
Albert from Google posted 9 hours ago saying "We just put out a potential solution. Could you try again?" but it still has issues for many users as of this morning.
So if you can't Google's search results, you are not alone.

Update: The issue is caused by BullGuard, more details over here.
