I've seen that in a few cases.
1. It was some old Dell that required the Dell keyboard to get into the BIOS.
2. The HDD was scrambled and to get into the PC we would unplug the PC then we could get into the BIOS and the work to get the PC working began. A new HDD, fresh install of the owner's selected OS then data recovery attempt on the old drive.
I'm having some trouble with my computer. When I hit the power button and turn it on the screen comes up with the bios and boot options to select. Then it shows "initializing" at the top and then goes dark...after that the monitor shows the "no signal" that seems like the monitor has been disconnected but computer is still running.
I have to turn power off in back and restart...when I try to get in bios or boot options with DEL or F12 it still does the same thing...won't go in to bios or boot options
I know the DEL and F12 I'm pressing are registering because if I press them too many times I hear the low pitched beeps sound telling me I'm pressing too many buttons lol. Any thoughts on what issue this may be?
