Pls
My Toshiba laptop Statellite C855-S5356, When switched on boots up to the bios stage then the screen will change to some multi-checker boxes (as if using a scratched DVD in a DVD player)then the screen will go off for about 10 seconds then it will repeat that process(on and off)but takes a longer time to come on again each successive time. I tried an external monitor but there was no display. I removed the harddisk but the problem remained the same, remove the battery-same.
I will be happy if l can get some help here. Thanks

I fully understand now thank you.
