Hi, I've been plagued with various BSODs over the last few weeks - I've put them in a zip and uploaded them. There's quite a few. They vary in error. One I had today said SYSTEM_SERVICE_EXCEPTION; another athrusb.sys. In fact there have been various USB errors. I thought I managed to fix that by downloading some file from the Microsoft website, but apparently not. Any ideas? Thanks. Edit1: Sorry, just read the sticky. My motherboard is the GA-X58A-UD3R. I believe it's revision 2.0. I'm also running 64-bit Windows, with 6GB RAM (I did notice something on the MS website a while ago about some .sys files moaning with more than 4GB)... Edit2: Been looking around on the web, and it seems that wireless USB cards can cause problems. This would make sense as I started using mine not long before the BSODs first started occurring. Can someone confirm this? And perhaps give me some way of solving it without stopping using it.
