Hi, I have come across this site trying to resolve the problem described in the first post. But, after downloading symbols, I am still getting an Module "Unknown" as the issue and I cant pin it down. I have uploaded a rar here: w2designs.dreamhosters.com/DPC_Interrupt.rar which contains the elt file. Thanks for any insight anyone can provide. I had daemon tools installed but it has been removed and I beleive these problems started before I had it installed anyway.
