Gear up ...
So my friend gave me his old Lenovo Y50-70 (i7 4710HQ + GTX 860M + 8GB RAM + 1TB HDD) for troubleshooting which wasn't booting up initially & just shutting down.
Draining residual charge from mobo & reconnecting battery made it show Win10 boot screen but it was turning off within seconds. Wasn't able to reinstall Windows. Apparently it was overheating, so repasted CPU & GPU & then reinstalled Win10 20H2. It was working well but wasn't able to install Intel HD graphics (latest available for that CPU), display was using Microsoft Basic adapter. Nvidia drivers were installing though but games weren't using GTX 860M.
Then I tried an old Win10 iso from 2015. When I installed Intel driver or it tried to get it via Windows update (presumably), the display will reset (as it happens when updating GPU driver) & stay in black screen (backlight is present). Tried this Win10 version multiple times, same end result, black screen with display turned on.
Tried Win 8.1 Pro latest version. If I install Intel HD driver manually or leave it for Windows update, the screen gets black & only solution is to reset Windows.
I left it running for few hours w/o internet or manually installing Intel HD driver, it runs fine with Microsoft's fallback driver but Nvidia GPU isn't getting used (both on Win 8.1 & 10). I have tried keeping CMOS battery disconnected for 30min or so & reconnecting, switching between switchable graphics & UWP (i guess integrated) from BIOS, but nothing helps in long run.
TLDR: If I install Intel HD driver manually or leave it for Windows update, the screen gets black & only solution is to reset Windows 8.1/10.
So need some ideas on what I can do solve the issue. In its initial condition, my friend gave it to some local laptop repair guy & he claimed mobo fault, but he didn't even solve overheating or corrupted Win10 boot. Is it possible that Intel integrated graphics is somehow corrupted on hardware level?
Any help is appreciated.
Edit: HDD's status is warning in CrystalDiskInfo. My friend is willing to invest in a 240GB SSD, if the laptop is working properly.
