Win XP Pro SP3 I have been getting many BSOD crashes lately. I thought it was my "Magic Jack" but even after unplugging this thing it continues. I received an error with on screen of a AVIpbb.sys file being the cause and after checking on the Avira site found a number of posts with various suggestions. I also ran a diagnostic of the latest minidump file and here are the results. It suggests that ntkrnlmp.exe is to blame. Not sure what to do at this point to try and fix it. Any help appreciated.
