Why does not Laptop wont turn on?

Model: Clevo NH55HPQ
So basically, after shutting down my laptop which was working perfectly in the night, when i tried to power on the laptop the next morning the screen was blank; the fan ran loudly with a orange blinking light. So far, i have took it to a shop and the following were tried:

1. Using another laptops ram
   1. unplugging and plugging the cmos battery wire
2. replacing one bios chip

It would really be a big help if you could help me out as i a student with uni classes starting soon and cannot afford a new laptop.

I have question previously and it was hinted that it may be a GPU, power-related or motherboard issue. I want to know where I can get it fixed and how much would it cost?
