When booting up my computer if no keys are pressed during the boot up then just before the log in screen appears my monitor will suddenly go into standby mode. I then have to press several keys and wait roughly 30 seconds until the monitor turns back on and the login screen will continue.
The computer doesnt continue the boot sequence whilst the monitor goes into stand by as when it goes off and when it comes back on the boot sequence is in the exact same place.
Anyone know why this is happening or how to fix it?
