Hello everyone, i hope that i can get some help here. this is a hardware problem i got. I did upload two videos to see my problem. 1st : youtube.com/watch?v=j1-p1VYAB7M 2nd: youtube.com/watch?v=h__Zs-hWC5Y In the first video that circuit shown is the one i blowed i did make a mass between this circuit and the carcass. i was checking for the 12v for the fan. any way this is not the problem. I checked everything but still won't turn on. in the second video it's shown the led blinking. I repeat this is not a GPU problem. Thank you everyone.
