I followed all the instruction on the thread regarding BSOD and memry dumps but the BSOD still appears regularly(every 5, 10 or 15 minutes) I have attached 5 of my dumps. Any help is GREATLY appreciated. Thanks again. PS. I tried using WinDbg to read the dumps - one pointed to some Norton AV file. So I removed the old, expired 2002 Norton AV that was installed, happens less but still happens(don't worry I use AVG now). The previous dumps pointed to other things and the new one another. Anyway here they are.
