i have a 5 years old Asus A42JK series laptop. Recently it kept on blue screen randomly and I suspected it was the harddisk problem. Didn't bother it though.

Few days ago however it fail to boot. Worst part is it can't even boot into bios, else I would happily format my windows and move on. When I hit the power button, it just lit on the LED, fans running but screen shows nothing. No backlit, no Asus logo, nothing. The caps lock indicator does react if I press the caps lock key.

I've tried to boot after I removed the harddisk, no hope. Remove RAM, same no hope.

Anyone experienced this? I hope this is not a hardware related issue.
