I keep most of my files on one PC at home but often work on another. When I access the files from one particular Win 7 system (only a few months old) reaching out to my 'server' PC, it is not unusual to have a problem. If I'm trying to email a file using Chrome, Chrome will pop up a DLL error and not send the file that I'm trying to attach. Regardless, look at one or two files on the 'server' pc, and I end up with 3 Explorer.exe processes, all of which are unresponsive. If I right click the taskbar, it too then becomes unresponsive.
The PC I'm working on is a SandyBridge I7 mobile running laptop with 8gb and a 450mbps trendnet wifi dongle. Nice, new, fast machine running Win 7 Home Premium. Except for this. The 'server' is running Win 7 Pro, 16gb also with a SandyBridge I7-2600k (not overclocked), 1gb hardwired (ASUS P8P67 Deluxe mobo).
Once the problem occurs, I try to use new task in task manager to shut down the PC. It nearly always hangs at 'shutting down'. I'm using shutdown -r as the command. I eventually have to power it off and then turn it back on.
Possibly related; system icons, especially the volume icon, keep disappearing. I do the fix from the MS answer site of deleting the 2 reg keys that control the system icons and all come back just fine, but a reocurrence always happens within a week.
The laptop is fully up to date. It's an HP DV7 with HP printers and lots of HP stuff on it. Runs wonderfully until this happens. It is set to 'hibernate' (shake the mouse and it is up in a few seconds prompting for login or finger swipe).
Any ideas, etc. would be greatly appreciated.
