Rafterman is closest, it's a random BF2 bug thing. Alot of people have had it recently including myself.

The only way I was able to stop it from being - regular - was:

A full BF2 and PR uninstall/re-install (and updates).

And unisntalling/re-installing punkbuster - (including updates).

And include defragging disk, update graphics and sound drivers, after uninstall (this will fix a few problems like stuttering/disconnects and so on, and should be done in any case). Remembering to turn off the computer and on again, at each interval for all to work properly (or it wont, very likely).

For more information on common PR problems, like crashing or kicks go to the Project Reality forums, and follow common instructions:

Finally, it is not overheating. Many people have stated (including myself) that all this has been checked (including checking for dust inside etc). There is a thread on it in the PR forum at this moment, though I believe this is not the first but I fear the only way to try to stop it happening regularly is to do as I found in the tips people gave: unsinstall everything, update your grahics and sound drivers, and reinstall everything (remember to reboot your computer at each interval). Basically a clean sweep. Also, I highly recomend to check the stickies on the top page (and not just the threads) for useful information on relevant crashes/problems and fixes, and follow these instructions - which at the end of the day boils down to as I said here for your specific problem (i.e. other problems like handshaking failure, can be fixed by more simpler solutions).
