I've had the same problem for like a YEAR!!! XP would lock up Explorer each time I left the computer alone for any length of time, and Explorer.exe could not be killed from the Task Manager. I've tried so many registry hacks and so forth that it wasn't funny any longer - I was ready to format c: and start all over again.
But then last week I just discovered the fix - Simple as pie. I set all power my options to NEVER turn anything off except the monitor (including never letting disk drives and network cards power off), never hibernate, and never go to sleep.
Problem solved!!! It hasn't locked up in days!!! It shows me that Microsoft may be playing some games here, trying to get us to buy Windows 8. Since when should it be hard to make a PC sleep and wake up without locking up??? - GRRRR!!!!
I use XP-Home with Celeron CPU Pentium4 at 2.8GHz and P4P800 Motherboard. I use 2 partitions on 1 320GB Hard Disk.
Since some days access from C to D vice versa was slow. Since yesterday all windows opened freezed! Opening them was ok, after that, no communication at all! Opened windows changed into "pictures". Sometimes even the task bar was not responding. Freezed as well.
Then I re-installed Windows. I used SP3 but rebooted to SP2. Guess what? The problem did not remove. The freezing stayes as it was! It concerns all kinds of windows: browsers, Explorer windows, all that I open.
Now the solution I found: when I open the Task Manager and then close it, the freezing stops and I can open and close windows.
Could anybody tell me what happened here?
Thanks in advance,
