I have been running windows 7 on my computer for quite some time and haven't had very many huge problems until recently. Now, sometimes when I start up my computer, it keeps on playing the asterisk sound that you hear whenever a warning message pops up. But when it happens nothing ever pops up, and that warning sound plays nonstop every couple of seconds and it is driving me insane. I looked at task manager to see if there was some process that would be causing that error message and I found nothing. I also went to msconfig to make sure that all start up programs were disabled and they were. The problem I am having now doesn't happen all of the time but when it does, it doesn't stop and requires restarting my computer.
And for the record, I am running windows 7 64 bit.
