PS CS5(64) OpenGL Drawing Not Enabled by Default

Question

Hello!  I have a PC I built last fall (PC2) I'm now grooming to be my main PC.  I'm preparing to rebuild my current main PC (PC1).  PC2 will soon have to do the heavy lifting.  PC2 has a performance problem;  I noticed when I was going through Photoshop CS5 (64-bit) preferences.  On the Performance page, GPU Settings area, Enable OpenGL Drawing is not checked by default.  (In my retiring PC1 Enable OpenGL Drawing is checked by default and the video adapter is listed in the area.)
I have this related oddity I hope we can troubleshoot:  When I drag to move or resize a window in PC2 only the outline moves or resizes until the mouse button is released.  (In my PC1, the windows move /resize as they are dragged.)  Any ideas where to start looking for the cause?
I had the identical nVidia driver on both PCs.  Just this afternoon I did a clean install of the latest nVidia driver, 270.61 on PC2.  It made no difference.
BTW, the motherboard, CPU, GPU (ZOTAC  ZT-98GES3M-FSL) and data HDD are the same model on both PCs.
Here's my PC2 List:
ASUS  P7P55D Deluxe  LGA 1156 Intel P55
CPU  Intel  Core i7-870  2.93GHz LGA 1156
DRAM  Corsair  CMX8GX3M4A1333C9  4 x 2GB DDR3 1333 (PC3 10666)
GPU  ZOTAC  ZT-98GES3M-FSL  GeForce 9800 GT 512MB 256-bit GDDR3
PSU  Corsair  CMPSU-750TX  750W
Drive 0  (O/S) OCZ  OCZSSD3-2AGT90G  3.5" 90GB SATA II
Drive 1  (Data) Hitachi  0F10452  2.0TB SATA 3.0Gb/s 7200 RPM 32MB
Drive 2  (Apps, Web site, Pgms & Updates) OCZ  OCZSSD3-2AGT90G  3.5" 90GB SATA II
CPU Heat Sink  ARCTIC COOLING    Freezer 7 Pro rev 2  92mm CPU Cooler
O/S  Microsoft  GFC-00019  Windows 7 Home Premium 64-bit

I'll appreciate any help that gets this resolved.
Thanks - Dave

Disable Indexing
Indexing is supposed to make it quick and easy to find things on your computer using Windows Search (that little box at the upper-right of Explorer windows).
But when you think about it, does it make sense to read all the files on your disk, extract everything you could possibly want to search for, and store it on that same disk another way?  To even consider indexing providing better performance than just searching the files, Microsoft must be picking and choosing the data they think you'll want to look for (excluding data you WON'T want to search for), where you'll want to search, and in what kinds of files, and in fact they are.  How could they know everything you'll ever want to search for? 
They can't.  Not everything is indexed, and never will be!
Try this:  Create a simple text file on your disk, in a temporary folder.  Call it "FindMe.log" and put in the text "This file contains important tax information".  Now navigate to that folder with Explorer and enter the word "tax" into the Search box at the upper-right.  Enter any of the words in that file!  Windows Search will not find the file, because it simply does not LOOK in .log files by default, and there's no fallback strategy - Windows Search simply does not index nor search for information for some kinds of files. Incredible!
All it takes is ONE TIME searching for something you know is there and NOT finding it to destroy your confidence in Windows Search.
And so they scan through your files endlessly, pick out the strings you might someday search for, and store them in yet another set of files (the "index").  As though your computer has nothing better to do.
Not only is the basic premise of this wrong, but it's not even implemented very well.  The index often becomes corrupted, and so Microsoft has provided functions for you to clear and regenerate it.  Just what you wanted to be doing - NOT.
Consider these shortcomings:
Some file types are simply not indexed or searched by default – e.g., .log files, and there's no fallback.  If you create a new file type no one's seen before, its contents will not be indexed.
Only strings they think you are likely to search for are indexed.
Because of poor implementation, indexing will miss things in some file types that are indexed – e.g., older Microsoft Word documents or files containing Unicode text (Microsoft's own invention).
Indexes often become corrupted and the Windows Search results fall out of date or it stops finding things entirely.
Indexing operations use computer time, increase disk wear, and interfere with your own access to your files.
In summary, indexed Windows Search operations in Windows 7 simply can't be trusted to find your data in your files when it's critical, and so they're essentially useless.  Searching for filenames using Windows Search actually can be occasionally useful (though the syntax to ensure it searches only filenames is a bit tricky), but this doesn't require indexing.
Moreover, indexing can actually interfere with file operations, causing your system to report disk corruption, because of an implementation error in indexing and NTFS (search the web for "Atomic Oplock", for example).
So indexing should simply and utterly be disabled.  This won't actually stop you being able to try Windows Search - on the contrary with indexing off Windows 7 will actually search your actual files (within the limitations listed above) just when you tell it to, and (since indexing isn't implemented very well) it may actually INCREASE the probability that you might find what you're looking for.
Here's how to disable indexing:
Click Start and enter services in the search box.
When Services (with little gears) comes up, click it.
Scroll down to the Windows Search service.
Right click it and choose Properties.
Change the Startup type to Disabled.
Click [ Stop ] to stop the service.
Click [ OK ].
Click Start and enter index in the search box.
When Indexing options comes up, click it.
Click the Advanced button.
Click the [ Rebuild ] button to delete the index.
It is a good idea to reboot after this.
So your searches work properly and you're not nagged by Windows to reenable indexing:
Open a Windows Explorer window.
Choose Tools – Folder Options.
Click the Search tab.
Click the button next to "Don't use the index when searching in file folders for system files (searches might take longer)".
Click Start and type group policy into the search box.
When Edit Group Policy comes up, click it.
Navigate to User Configuration – Administrative Templates – Windows Components – Windows Explorer.
Enable the Turn off Windows Libraries features that rely on indexed file data entry.
If you do not have the Group Policy Editor on your version of Windows, change this registry entry:
HKCU\Software\Policies\Microsoft\Windows\Explorer
