This happens on two different PC:
win2000pro english, SP3.
Every 2 or 3 days, win2000 hang.
This hang is very strange, because is not an hardware hang but surely is software.
System is working good for 1-2 days, then occasionally, in different situations, some program don't close his windows, don't minimize when i press minimize button, don't appear when I switch from one prg to another and so on.
When this situation starts, in about 20/30 seconds I'm able to do less and less things, up to I can do nothing more.
The only thing that continue do work is ALT-TAB that show task-switch-panel, but when i release TAB, the selected prg don't show his window.
The mouse too is working, and I can give focus to different windows.
At this point, the only thing I can do is a hardware reset.
If I leave the PC unattended for 5-10 days, it continue to work correctly, but just when I start to use it, it hangs in the first 5 minutes. It seems that the bug (or virus) is waiting for me to start to hang my machine.
Strange things is:
It hangs every 2-3 days, not before, not after. I have to reset PC every 2 or 3 days.
The "hang" is starting with little happenings, and become bad and bad in 20-30 seconds, up to hang all system.
It happens at the identical mode on 2 different machines.
Oh, I forgot: I scan system for viruses, but no virus found.
I use AVG antivirus from www.grisoft.com, updated.
Someone has suggestion?
thank you so much.
PS: I installed now SP4, I'll see if it resolve.
