Hi Bob…,
and at the same time of the explorer crash TrueVector timed out.
Not related to the Windows Operating System –but as a "very long-shot precaution" I recommend that you update your Zone Alarm.
When you get to the choice-point in the installation for "upgrade the current configuration" or "clean install"
(sorry, I don't remember the exact wording) please Select "clean install". This will uninstall your current Zone Alarm and replace it with the most recent updated version. And you'll get the Alerts for "Allow" or "Deny" for a while, but ZA will learn what you want to "Allow" as you checkmark the "Remember this setting" box on the Alerts. I know it can be annoying, but Soon you'll not often see Alerts, unless something bad is happening and you'll be glad it was stopped and gave you an Alert.
Here's Secunia's blurb on the potential threat:
http://secunia.com/advisories/9459/
Note: I am NOT saying that your Zone Alarm vsmon.exe is faulty, or that it is the primary culprit in causing these crashes.
What I am recommending, is that updating and freshly installing Zone Alarm "covers your bases" without any downside risk and very little time consumed with the download and re-installation routine for Zone Alarm. And as an added Bonus, you'll have the updated version of Zone Alarm, which we should all be running if we run Zone Alarm.
OK, I can hear your comment already: "Hey, I just installed Zone Alarm this month and that Secunia warning is from 2003"
Your ZA -

Please check for update anyway, by going to:

Not much lost by giving it a try, and much to gain!
If ZA says that you have the latest version already, then download the current installation version anyway.
Then go off line and Uninstall your Zone Alarm and Install the new current installation.
This may remove any remnants that could be related to the older corrupted vsmon.exe.
Some would say this is overkill and too much trouble.
I recommend this because of your persistent symtoms and no other exclusive clear cause.
Back to your main symptom:
I recommend that you Run Error Checking a couple more times.
I recommend that your Run sfc /scannow at least one more time.
At this point, if the episodic "crashing" via Windows Explorer continues, then you either have a problem with the "size" of the files being accessed in Windows Explorer, as compared to your immediately current freespace, or you still have those large files "fragmented and spread" all over your C:\ drive, or there is a problem with Windows Operating System.
Recommended course of action:
Continue gaining additional FreeSpace
Defrag
Consider Uninstal - - Reinstall of various of your gaming applications… with a reboot and Defrag between uninstalling and reinstalling gamin applications, especially those that Defrag lists as "unable to defrag"
Consider a Paid Product Defragmentor Tool VOPTXP from Golden Bow Systems
(download a 30-day trial version here:
http://www.vopt.com/VoptXPd.htm)
I've used VOPTXP on numerous XP systems and found that it does a much better job than Diskkeeper from Executive Software (who also licenses their program to MS Defragmenter so don't buy Diskkeeper because you already have it, kinda/sorta)
A major advantage I've noticed With VOPTXP is that it deliberately defrags the SWAP/Paging File, consolidates it into a single chunk of space and places it right up front at the beginning of the Hard Drive, for Rapid Access.
Secondarily, I've noticed that VOPTXP is apparently able to defrag many large gaming files.
For instance, my Son plays WOW, Everquest, CallofDuty2, BattleField, MedalofHonor and such, none of which were effectively defragmented by the MS native/(Diskkeeper) Defragmenter tool, and were nicely defragmented and consolidated in continguous chunks by VOPTXP.
Disclaimer: This is not an advertisement for Golden Bow Systems, I have no interest in them, I am not receiving anything from them. I don't even use them on most of the machines that I service.
Further Disclaimer: Your results and mileage may vary. No guarantee that VOPTXP will effectively defrag your gaming files, nor if it does that it will make any noticeable difference.
But since you can get the 30-day free trial, you may just as well give it a shot.
With all the above complete, if your problem persists, consider doing the non-Destructive, Non-Reformat Repair Installation as outlined in the Fred Langa article I linked previously.
Note: Langa's Non-Non, Repair is also referred to as the "Dirty Repair Installation", kinda tongue-in-cheek, but accurately describing that it leaves all the rest of the system/system settings/applications/data in place exactly like you are familiar with at the present time. It simply removes and replaces the contents of some system folders, files, registry entries and reference .cab folders. You'll have a single, fresh and non-corrupted inccidence of Windows Operating System on your machine, with no extra or duplicate files, but… you'll also have everything else you previously had installed, saved, and organized on your machine.
So why am I recommending Langa's routine over MS's or others?
Other routines may work for you, but Langa's is least likely to cause you difficulty on this still relatively full hard drive. Least likely to cause you difficulty…. that's all.
Other Recommedations for later consideration.
Best option would be a complete Reformat Separate Partition and Clean Installation of Windows XP.
But… That encounters the need for all your machine's drivers and driver updates, hardware firmware upgrades, loss of all applications/need to reinstall applications, need to save all data files/or loss of data files.
The greatest advantage of this "later cosideration" is the plan for a "Separate Partition" for Windows.
If you made a 25gb Partition exclusively for the Windows Operating System, and then later for whatever reason decided to work on or re-install Windows, you could do so without interferring with your applications, configurations, and data.
It just makes good sense to keep Windows Separate from those other elements.
So, later, when you're ready to Reformat, or ready to add an additional Hard Drive, consider creating a separate Partition of C:\ exclusively for Windows.
Thanks for keeping us posted on your progress.
Best Regards
