@youssefashraf It looks like the arching originates from your PR317. Your image has already been zoomed in which makes it appears slightly fuzzy but it looks like the solder pads are definitely not what they should be. I would replace that component. It is a 0.01 oHm 1% resistor in a 1206 package. If you check the schematic provided by @jayeff you see that this resistor is for the charge controller PU301 circuitry which could be the reason for your computer not turning on. Check PQ317 and PQ316 for any damage and power.
