Random crashes to desktop

[perylousdemon]

Hi, everyone. I've been searching the forums (and other websites) for solutions to this problem, and I can't seem to find any, so maybe someone here can help. I am constantly having the game crash to desktop with a black screen and the error message "Dndclient has experienced a problem and needs to close", or sometimes the game will just disappear and I'll receive no message at all. It seems to happen randomly; I can be standing around doing nothing, running a quest, zoning into a new area (which I know is a problem for other people as well), or browsing the AH. Sometimes I can go days without a crash, and other times I crash every five minutes. I've tried reinstalling, updating my graphics card driver, lowering my graphical settings... Nothing has worked so far. I did notice after running my dxdiag that my page file is pretty large, so I'm wondering if that has anything to do with it, and if so, is there any way to reduce the size of it? Thanks in advance.

I know toon-swapping too often can cause crashes, but in most cases, I've been on the same character since I logged on.
