I am wondering if my HDD is failing. Lately when I go to turn on the computer. It will not boot to windows and say "Reboot or select proper boot device or insert boot media in selected boot device and press any key." After a restart or two it boots up like normal. Also, just this morning I am told my computer started making weird noises so my wife shut it down. upon turning it on it booted straight to the BIOS. I was unable to see if the boot sequence changed or see my HDD. I turned off the computer and rebooted. Windows booted back up properly then.
