I don't know what to do.
I mostly use it for video editing in Sony Vegas Pro 13, light gaming and a lot of web browsing. I went to a repair shop and the guy fixed it at first, saying it has malware and it was overheating (Like mad, I know I'm stupid for using it without a fan). So I bought a fan, went home and a day or two later, the screen turns black and a popup shows "Display driver AMD has stopped working blablabla." and then goes back. Now it's just stuck on that blue screen thing. I can't boot into Windows at all.
The guy said that the driver should be replaced for P8,500 which is $179.
P.S. I'm not rich. And I typed this in my mom's slow-ass Asus laptop.
