Hello! Thank you in advance. I'm on a Win8 computer, which shut down totally just now. I tried to solve it without restarting, but it didn't work. Heck, when I did decide to restart, it took ages too. This is a pretty new computer as well. Any ideas or advice on what went wrong and what to do next time, would be VERY appreciated! I've tried to document the symptoms: Sudden connection drop. Hasn't been possible to reconnect or anything. Some programs hanging and crashing. No networks found. Not possible to restart network card. Programs like Intel Wireless Pro not wanting to start. Spikes in RAM, CPU and HDD performance. Longer than usual time between switching users. "Radio switch device" crashes device manager if disabled, sometimes.ENE TECHNOLOGY INC. Windows also says it can't start this unit. Code 19. Wireless card doesn't activate, despite brief pop up which says it activated Frozen, unclickable remains of some windows/programs, sometimes stay and continously block the view. Unmoveable. Disabling VirtualBox network plugin doesn't work. Crashes and its window stays unmoveable. Keyboard shortcuts such as Windows key + R start to become unresponsive. Network diagnoses, whether in general or on individual network cards turns up completely blank. In device manager, the wireless card says it doesn't have any drivers installed. Yet there ARE apparent viewable driver files. Weird??? Tons of errors in a few services today, as per the Administrative logs. NvStreamSvc, DistributedCOM and Service Control Manager mostly. Warnings for DNS Client Events. Restarting explore.exe doesn't help anything and the Windows 8 "Charms" don't work at all either on the user acc where this all started. But on the admin acc it does. The bottom right network icon has the usual yellow triangle, but no charms menu appears if you click it. So you can't even check WiFi networks.
