Hello, I'm French so sorry for my communication, My new computer with Vista 64 meet recently some reboot problems. I installed recently special software : Virtual PC, VMWare, Daemon Tools, NCP Secure Client (a VPN client), kaspersky internet security is always my security program for a long time (avp.exe on the dump...) There are 9 dump files but it is almost the same. I need all the programs I talked about, so I ask you to have the culprit. Thanks for helping. If you need more informations I will bring it. Edit : I uninstalled and reinstalled Kaspersky, no more BSOD yet... Strange, I hope it will stay good.
