First let me give you some background:
This notebook came with two graphic cards. After four years, it chose to not boot anymore overnight (fans go on, but display stays black; no BIOS, no nothing, just black). Detaching the second graphic card solves this problem and the system is booting like always. Hate when that happens :-D
The only thing I changed right before was enabling the SLI mode. But why would it be a problem?
I've already tried the following:
- Reinstalling some drivers, updated everything to manufacturer standard
- Checking SSD, RAM, temperature
- Recover Windows 10 (this device has a button to boot a recovery install tool)
- Updating the BIOS
- Flashing the graphic card (not successful though)
- Check all cable connections
- Insert the second graphic card ten times
- Do the twenty seconds power button magic
After days I think either the second graphic card is broken, or something with all the driver/BIOS/flashing stuff went crazy. So here comes the question for the next try:
Will a clean Windows installation revert bad BIOS flashes?
This Lenovo system comes with so much unnecessary software and I'm not sure what a "system recovery" is really doing, so I think best is to clean install Windows 10. But this only makes sense if this step will revert flashed hardware. Is it?
I'll be glad to have this system boot properly!
