oxc000000 error with multiple applications???

[yoshiserry]

i had only recently reinstalled picasa, and the application error came up, and worse the computer got a fatal error with a blue screen and came up with i believe the same error code. oxc0000005 error. the error didnt let me into windows.

then i turned the computer on one day n it logged in, i used it to surf the net insure if picasa was the problem (picasa is a photo editing program. btw from google.)

then i restarted n it came up with the same message not letting me into windows. so i thought well i should uninstall picasa. i did, n it seems to work fine, but i still constantly get the application. i wanna work out what the problem is, hope its not picasa because i use it often to organise photos.

does picasa cause this error, anyone had this problem? anyone got any ideas?
is it safe to reinstall picasa? im struggling without it back to manual to organise them.
any help greatly appreciated.

anyone any idea what caused the fatal error?
