A problem has suddenly developed in which I am unable to access BIOS or get into Windows Safe Mode.
I started when I was burning a video DVD -R in which about halfway through
the burn, the DVD ejected and an error message saying there was a burn failure.
Only half the the DVD had any video but no problem with DVD RW discs.
Then the DVD and CD drive disappeared from Windows Explorer, but the DVD drive still appeared in the Control Panel and still worked.
Another time, my secondary harddrive disappeared completely but I have it back now.
I then tried to get into BIOS but when I pressed the DEL button, nothing happened and likewise with Windows Safe Mode. I tried shutting the system down abnormally which gave me several options when re-booting but the up and
down buttons didn't work so had to wait for auto re-boot.
I have USB keyboard and the mob is Gigabyte GA-K8NSC-939.
I don't know if the burning problem is related or a separate issue.
