Hi all, So i'm writing this from Safe Mode with Networking as that seems to be the only way to keep the system stable. I'm on a Win7 Pro x64 system (q6600, 4GB DDR2 RAM). I was working on my computer last night with zero problems. I shut it down and then today I have the following symptoms. Once i boot, i can open folders on the desktop and open my firewall status etc. However as soon as i click on Firefox, open My computer and select any of the hard drives, or click on the Start menu and start to type in the search field, Windows 7 will freeze and explorer.exe will eventually crash without an error report. It will simply tell me to end the process, after which i can only view the wallpaper and nothing else works. (No right click menu etc). When in Safe Mode with Networking, everything works as expected. I can run firefox, navigate all 3 harddrives and search in the start menu. I've just finishing a MalwareBytes Scan with the latest updates but nothing was found. Any idea what it could be and maybe some suggestions to track this down? Thanks!
