Hi, I have recently had a run of BSODs all with different causes. They all seem to have the same readout for BugCheck (BugCheck 1E). It all seemed to start after I ran disk cleaner and disk defragmenter. I will upload all four minidumps. We have also had some network virus issues on another PC in the house. I cannot specify an exact cause, so I hope you can help me with this. Thanks, Rob.
