monitor keyboard and mouse not working

[rayancaleb]

Hi,

I switched the system on this morning and whilst the light on the tower unit went on to blue and it powered up , neither the monitor, keyboard or mouse came on.

The blue light on the tower unit normally goes to amber and into sleep mode after 10 minutes if not in use , today it stays on blue.


I would greatly appreciate any help.

Please help.

Thanks!

I didn't find the right solution from the Internet.
