Acer 4820tg turns on no display fan turns on for 2sg after bios flash

[tiagooliveira95]

I have an acer 4820tg, it turns on the fan speens for a breif moment then stops, blue light stays on, if i leave it like this for ~60sg the fan jumps to 100%.

The laptop was working normaly but with no aperent reason i started to get atikmpag.sys, intalling drivers and software didn't help i updated the bios sucessfully and still the same problem.

I went to the bios and changed the graphics form switachble to discrete and it stopped working, clearing the CMOS didn't help so i tried to flash the bios with the fd file, and the pc refused to turn on at all.

i flashed the bios and kbc with this: http/1bios.ru/bios/notebook/acer/aspire/4xxx/acer-aspire-4820tg


the pc turns on now but i get no display and the fan only spins for 2 sg

I also tried to boot with one RAM stick same result, no beeps.

If someone can help me with this i appreciate alot

You may have a dead video card, which in laptops means dead motherboard.
