When I log off, log on, restart, shutdown, or power on, my Windows flashes the log off, log on, shutdown, or power on windows 7 screen and noises twice. So I hear two logon sounds, two logoff sounds, it looks like explorer is started twice (or restarted) as the taskbar flashes...

What is wrong with my computer?

Thanks

EDIT: I just ended up reinstalling windows after formatting my hard drive. The problem is fixed now.

Hmmm. First, have a look through all the enabled system sounds to see if any other event is playing the log on/whatever sounds. Painstaking process I know...

Next idea- disable the log on/whatever sounds from playing (change to "No sound") and see what effect that has. Does the sound still play once? Not at all? Let us know...

Well the sounds are just a result of something worse I think... Disabling the "exit windows" sound stops the sound, but the logoff screen still flashes. And when I log in after restarting, the log in screen flashes too. I hope it doesn't have anything to do with my copy of windows being a student edition (meant only for upgrade), yet I made a bootable .iso out of it and did a clean install? – eqzx Dec 23 '09 at 16:48
