(Solved) Users table corrupting

Hi
I have done a fresh install on a new site recently and it all went well, but ... lol there is always a but.
The users table is corrupting every few days, I can repair it using phpMyadmin but it tends to drop a user off, not the same one evry time.
Im backing that table up every day now but have no idea how to stop this happening or what I can do about it. The forum is growing nicely so its a real problem for us.
Any advice or help appreciated
cheers
