Thanks for your response. Sadly, it seems that I was unable to establish any relation between the Logitech and the problem. I removed
the drivers from the startup as you suggested, and I unplugged the
Logitech device that broadcasts to the keyboard and mouse. I plugged in an ordinary USB (wired) mouse, and rebooted.
The problem still remains, although sometimes it takes a few minutes to trigger it. To recap, I click on the start menu and hover with the mouse over the various menu items. Eventually that triggers the screen blackout, which lasts roughly 5 seconds. This is driving me nuts. Particularly, when I want to scroll down the list of programs to find something.
Am I doomed to wiping the disk clean and starting over again with vista? I do not have the time nor the patience to remove individual software programs (or drivers) one by one to try to find the culprit.
P.S. My video card is NVIDIA GeForce FX 5200 (with the latest vista driver), and my monitor is (which is a Sun 24.1" LCD Monitor v4)
uses a generic PnP Monitor driver for vista. I installed the monitor five months ago, so it has been working fine long before this problem surfaced.
Is your logitech software loading at startup? Run msconfig from the start menu. Click the Startup tab and look for logitech programs. Uncheck the logitech modules. Click on OK. Then reboot. Your logitech programs and drivers should not be running now. See if that isolates the problem to logitech. If so see: http://www.vistax64.com/drivers/150128-logitech-g7-wireless-mouse-problems.html , and google for more with "logitech", "wireless", "problem", "hang", etc. You'll probably find an answer. Also go to the logitech site and make sure you have the latest software and drivers for your devices..
"Howard Haber" <haber@xxxxxxxx> wrote in message news:%aGGk.2597$as4.1584@xxxxxxxxxxxxxxxxxxxxxxxI have noticed a particularly strange behavior on my windows vista system (a Dell Optiplex GX270), that just started recently. Here it is. When I call up the start menu (not the classic style), and my mouse hovers in that region of the screen for about 10 seconds or so (whether I am looking through program lists or whatever), the whole screen will suddenly go dark for about five seconds (for no apparent reason) and then return to the previous state.
This is of course quite frustrating when I am going through the program list looking for a particular item. This blackout can occur a few times before I finally reach my target in the start menu. This seems to have nothing to do with UAC (which is turned on). This odd behavior started after I replaced my Dell wired keyboard and mouse with a wireless keyboard and mouse (Logitech).
In case the latter has something to do with this, I plugged in a wired USB mouse and removed the wireless mouse from the room. However, the same problem remained. (Windows update recently upgraded to Vista SP1, but this was a few weeks ago, so there does not seem to be any connection.)
I can find no help on the web, and I don't even know where to begin to troubleshoot this problem.
If anyone out there has any suggestions (short of wiping my disk clean and starting all over again), I would be most grateful.
