Got a windows 7 machine which is supposed to run 24hrs a day 7 days a week. Anyway I noticed the free memory gradually disappearing and ekrn.exe had shop up from 45mb too 257mb and still increasing. Now whether this is due to a interaction between weatherlink 5.83. Weather display virtual vp and active webcam I don't know. I've now removed nod32 and using microsoft security essentials and watching what is happening. If the problem remains the machine will start crashing programs in about two days time. The pc ran memcheck all night without any errors.
