Hi, my laptop worked fine on saturday night. But now an hour ago i tried to start it and it would not boot. Power button light and wify mute button lught would just pulse and screen had that brief backlight flash. Same was happening on batt and power. I unoluged all but cmos batt. Held power button 30/40 secs. And plugged all back. And i would get caps lock light flash 3 slow, and 3 fast. Fan would slowly ramp up to full throttle. This happens both on batt and wall power. I ruled out ssd, hdd and both ram sticks. I need fast help with this as i wanted to use this laptop as nas brain for my das. The only noteworthy thing happening was win update before i shut it off. I tried power button with win logo + b and +v combo and nothing.
