Could your Virus checker have attacked one of the system files. This is becoming more & more of a problem these days.

>I was working with probably a dozen applications open and all was fine.
>I went and tired to do a SnagIt capture (had done many earlier) and the application 'froze', though other applications were still accessible and seemed to be working.
>
>I got to where I needed the capture that was frozen, so I decided to "End task" on SnagIt. There were 2 of them running - the base program and the (attempted) capture.
>Neither would stop, though eventually they seemed to.
>Trying to restart SnagIt didn't do anything. I'd click it in the Programs list but nothing started.
>
>So I decided to shutdown (restart) figuring that a reboot would solve all.
>However, no matter how many times I clicked on Shutdown (which did produce the dialogue each time and the screen did do its greying thing) and then either "Restart" or 'power off', nothing happened. So I ultimately hit ctrl+alt+delete several times, waited a few minutes, then powered off.

>When I powered on a message was displayed that Windows has trouble last shutdown and asked me what I wished to do. I first tried 'start normally' and the Windows logo screen appeared momentarily, then a self-reboot.
>Then tried 'safe mode with networking'. This time a long list of module names was displayed on the screen (probably hundreds) but then that stopped and another self-reboot.
>Same thing after specifying "Safe mode".
>
>I tried remove RAM, even though POST was OK, but no joy.
>
>The system has a RAID1 (mirroring) C: drive, if that matters. I'd remove a drive one at a time if I knew how.

>Any ideas as to what might be wrong here? My sense is that the HD has access problems, though I had no warning of such and have no way to confirm. I'm guessing based solely of not being able to boot INTO Windows.

>Any ideas appreciated.
