I used BlueScreenView for see the Dump files.

Please tell me what would you do to solve this, I have not run any diagnostic test and I want to know from where to start. I use daemon tools lite and I have heard that causes a lot of BSODs. All my software are up to date windows too and I have already scan my pc with Norton internet security 2014 with no viruses...please tell me what u think.

Thank you in advance!
