1st try with hdmi / vga connected second monitor then try to install or try to turn on laptop still issue persists
it a hardware failure gpu dead.try below step it worked for me.
1. need "air heat gun" and "heat thermal paste".
2. disassemble laptop fully.
3.remove heat sink with fan from motherboard clean the fan dust if your have and now able to find chip process and AMD Gpu in laptop.
4.read the chip which one is GPU and take "air heat gun" blow up-to 5 to 10 min then wait to cool 30 min don't touch chip.
5.put the thermal paste on both intel proccess + amd gpu chip place the heat sink carefully.and assemble your laptop
6. turn on install any catalyst driver .i have install 15.11 catalyst (don't install crimson driver it burn your GPU)
it working fine for me...
