Goodday guys,
I switched on my PC this morning, it switched on, then display a multicolour on the screen and then switch off without even booting, or staying up to 3secs.
It's a new laptop I bought last year and this is the first time am experiencing this.
The screen and harddrive is very well okay because it has work fine before but when I switched it off, charge the battery and switch on again, that same problem comes up again.

Please what could be the problem?
