"Have you run a full disk check to make sure you aren't dealing with data corruption on your drive? If that isn't at least part of the issue, have you tried disabling DEP (Data Execution Prevention)?
DEP always results in AppCrashes for me so I ended up disabling it entirely. I have installed some XP drivers and software so I'm not entirely surprised that I've encountered this. If you've done the same this might be part of the issue.
You might want to try this, but be aware that you are disabling a rather important protection feature of Windows...
To turn DEP completely off in Vista open a command window (or click on Start/Run and type cmd and hit return) and type the following:
bcdedit.exe /set {current} nx AlwaysOff
To turn DEP back on:
bcdedit.exe /set {current} nx AlwaysOn
In Vista, the effect is immediate - no reboot required.
DEP can be somewhat fine tuned through the GUI...
- Right click Computer, select properties (or CP/<Classic View>/System)
- Select Advanced System Settings (in the left pane)
- Advanced tab (you should already be there)
- Click Settings under Performance
- Select the Data Execution Prevention tab
- Select "Turn on DEP for all programs..."
- Click Add and browse to \Windows\System32\Rundll32.exe
- You might also want to add \Windows\explorer.exe
This is rather extreme (and should only be done temporarily for troubleshooting), so you might want to consider backing up and reinstalling if no better solution is found for you. I realize that's a huge hassle, but better safe than convenient - Vista is definitely more robust than XP, but when it breaks it seems to break really bad - as you've experienced.
Good luck!"
