Just got laptop new last week. Added a Belkin router and Belkin network card, Adaware, Norton Antivirus and Spyware Doctor. Computer crashed 3-4 times per day with BSOD and report of "error caused by device driver," so I got rid of Adaware, Norton and Spyware Doctor and replaced with Avast! antivirus and Windows Defender. No improvement. I am attaching 7 minidumps. Help!
