Excel 2007 : "Excel cannot complete this task with available resources" Crash Error in Office 2007

Strangely, the last couple days I've started to get crashes of Excel and Word 2007, usually related to either when it tries to save AutoRecover info or opening another workbook. I've got 2 Gigs of ram, plenty of HD space, and the workbooks themselves are small (less than 500K). I rarely have more than 2 open. As Word is throwing the same issues I'm guessing it's something shared by these two Office applications.

I'm using Windows 7 Home, and the only application I've installed recently is Turbotax 2009. Office Diagnostics didn't pick up anything, and I did a Repair of the installation but the problem persists. My paging file was system managed originally, and in hopes of solving the problem I upped it to 3GB, which did not solve the problem. PerfMon shows 1GB or so free memory at all times anyways.

Word gives a slightly different error indicating a system resources error. I will update the thread when I can get a screen shot of it.

Any ideas?

My Word Error (on saving a 17K document):

There is a problem saving the file.

Usually this is because the disk or floppy disk is too small for the file or is full, RAM memory is low, or there is a permission problem with the drive the file is being saved to.

If the amount of disk space for a paging file is low, save the file to another drive. If the RAM memory is low, increase available RAM. If permissions to the drive do not allow you to save to that drive, save the file to another drive or request permissions from the administrator to save files to the drive.

Note: This error can also occur if the computer is running a version of antivirus software that is not compatible with the Microsoft Office system or needs to be updated.

ANY help is appreciated

Ah, it looks like on 1/13 I downloaded and installed Office 2007 SP2, along with a bunch of security updates. This corresponds exactly to when the issues began. I'll re-install from the blank disk to revert to SP1, and post what happens.
