Every so often: "Missing Operating System"

post #1 of 2
Thread Starter 
Around once a week or two, my POST will take a good moment to load and then the computer will state "Missing Operating System". A reboot seems to take care of this just fine, but it does happen from time to time.

Does this mean my Hard drive is dying? Or is it just a random glitch?

check or replace your SATA cables, run your manufacturer HD scan.

In BIOS just put your HD as your first boot device. I've seen card readers with a memory card inside get in the way of POST.
