Odd application errors

[Gearbot]

I've been having some rather weird errors - they appear whenever I boot or turn off my computer and also quite often when using certain 3d programs (such as ShiVa). The error can be one of two things - the one thats most annoying is

nvcompress.exe

The instruction at "0x7c9100e8" referenced memory at "0x00900010". The memory could not be "read"

the other is about the same but with rundll32.exe

I've scanned my computer and clean my registry but nothing changes.

Are you getting any Blue Screens?

No blue screens just random pop-up error messages.

nvcompress.exe is a driver for your Texture Tools 2 software. If you do a search is on the net quite a number of people are experiencing crashes from this driver.
