Microsoft Lock Up Issue

I've been having a weird issue with Microsoft Outlook lately. I'll be using it and it'll work fine, but if I go idle(leave the computer and lock the computer) for more than 15-20 mins and come back, Outlook will be frozen. It just started happening recently. I suppose I could backup my info and reinstall it, but i'd rather find out the problem and try and fix it before I go and do that. Any ideas?

 

Late Edit: I should add that it's just basic Outlook with no special add-ons. Also, I recently upgraded to Windows 7 32bit.

 

May need to run a repair on your Outlook file.

Also if that doesn't work, try the following.

And if that doesn't work, do a CHK DSK

 

Did the check disk, came back with no problems, but using the scanpst program, it did find 21 errors. Only way to see if it worked is to do a trial run. I'll let you know if it happens again.

 

We'll be here awaiting the results.

 

Nope, it's still freezing up. It seems to have gotten worse. I'm trying to last one, which is deleting the FORMS folders. I'll let you know if it's still freezing.

 

Any word back?
