I'm having a strange freeze on my machine (desktop, not laptop). It's like the system crashes, but only half-way.
This happens most often when I'm away from the computer for an extended period of time. I'll come back and the power saving features have shut down the monitor and hard disks. When I move the mouse, everything comes back on. However, when I attempt to log in by clicking on my userid, the "hot" area doesn't respond to mouse click. I'm unable to use the keyboard either.
It's happened several other times as well. Occasionally, it'll happen while I'm using the machine. I was able to reproduce the issue every time while using Dreamweaver, however, I've since uninstalled and reinstalled the product and everything appears normal.
When it crashes while I'm using it, i can still move the cursor. When the cursor moves over the windows task bar, the cursor changes to allow me to widen it, however, it still doesn't respond to click. When I go over a text box, the cursor changes to a bar, but I still can't click nor does the keyboard accept input (alt-tab, windows key, nothing works).
I first noticed the problem a few days ago. Firefox had an update, and it's possible that there was a windows update, but I'm not 100% on that. I have Anti-virus installed and up to dat and no issues have been discovered. I have run Spybot Search & Destroy with only the standard tracking cookie popping up. I'm using zone-alarm and have am behind a wireless router. GRC.org shows no port issues.
I have updated all of the device drivers for my machine from Gateway's website. I have disabled the hard-drive sleep feature and turned off hibernate mode. I have scanned the hard-disk for errors, and only get minor ones after a crash. Unfortunately, the only time I can guarantee that it'll happen is after it goes to sleep.
This is driving me absolutely freaking crazy. Anyone have any ideas?
