My Guild Wars is Broken?

In the past 2 months my Guild Wars has come up with "Repairing Data Archive..." two or three times now. After about 5 or 10 minutes it's done and my Guild Wars runs like normal again. Not really a problem, but kind of annoying.
Anyone know what's wrong with it? Or anything I can do to fix it?
Any help is appreciated!

(If there is a thread like this already I apologize)

Yes I get that every now and then, I have read it could be any number of things, hardware/software no real answers. It has been happening to me for months and haven't done much to get rid of it just kinda got used to it. Everything else seems to work fine with this computer so I don't know. Reinstalling the game usually doesn't work either.

Probably a .dat, delete it, then -image

There is probably something causing corruption in your .DAT file, and that file idn't getting the repair it needs fully.

I'd delete it and do a -Image to re download a fresh one.

It could several things. Like Bob says, something is corrupting your gw.dat file.
Some likely suspects:
- overclocking - if you are overclocking anything, set it back to normal.
- bad RAM - the gw.dat file is BIG and when it is being read and written to, it can occupy areas of RAM that aren't often used, so the problem doesn't show up all the time. If you also get registry errors though, that's a good indication of bad RAM.
- bad hard drive - gw.dat may be on a bad sector on your hard drive. You could run a error check on the HD - make sure to enable checking for bad sectors.
