winspww2 crash to desktop after 5 mins

[Mobhack]

Well - if it happens after some time then you reinstall, and the problem again takes some time to happen again then reappears then something is probably wrong with your machine.

I will assume your machine meets the minimum specifications for the game as set out here (game requirements). If not - that needs addressing.

I would suspect you may have some sort of disk drive problem -lost clusters etc or possibly even a bad sector. I would try a defragmentation of the drive and a surface test as well.

cheers
