sudden "operating system not found" (but reboot is fine!)

This has happened twice. It started last week while running itunes (playing music) and nothing else. happened again last night, also same scenario.

For no apparent reason (machine is less than a year old) the computer will go to a blank, black screen and the message "operating system not found" will appear. I press and hold the power button to turn it off, I turn it right back on, and it's fine.

I did get a BSOD last night, but itunes wasn't running and I had just connected my GPS running watch through USB. I can't tell if these are related, of course.

I run MS Security Essentials as my only virus protection, and yesterday I ran a Spybot scan which found nothing but a few tracking cookies. If there are log files that someone can point me to, I'm happy to post them.

Hello !! Welcome to SF !!

Go to your BIOS setting and check the boot order make sure Hard disk is selected first. I have seen if the boot order is different sometimes we used to have this problem. Make sure your USB is never plugged it while rebooting the System.

Hope this helps,
Captain
