I had the BIOS message:
BIOS has detected unsuccessful POST attempt(s). Possible causes include resent changes to BIOS Performance Options or recent hardware change. Press 'Y' to enter Setup or 'N' to cancel and attempt to boot with previous settings.
I know for sure there were not any hardware changes and understand that RAM or hard disk can causing the problems.
But there can be a case when nothing is wrong with hardware.
Can a sudden power off (from power board, for example) of a computer be another cause when I'm already using OS?
PS. From my experience, to get rid of this message, it's better to press
Y and then
F10 (to save and exit) instead of pressing
N. If you press
N, you may get same message again.
