Hi Josemikhail,
Unfortunately, I don't have a G75VX unit around to check, so we might want to ask G75VX owners running the ASUS Windows image which filename they see on the C: drive when they show the hidden files.
I have tried this procedure on the G75VW before though as mentioned in this
post (#32), and the filename was G75VW.bin, so I would try G75VX.bin if you don't get better suggestions.
Also, curious where did you get the bios file? It's probably better to get the *.bin file from the original ASUS Windows image for your notebook model if possible, otherwise, if you are renaming a bios file from the ASUS G75VX download site, try the oldest version you can find since the G75VW.bin file that I was able to flash successfully turned out to be an older version. I also remember trying to rename some newer G75VW bios versions that didn't work with this procedure, but the G75VX may be different.
Not sure if your local ASUS repair office is able to re-flash bios chips without replacing the notebook motherboard, but if you think it's worth the trouble, thought you might want to discuss with them. If you're interested, try this
contact page.
I'm still wondering why the system stopped working though and if there is some problem with the bios chip or something else in the notebook.
You might also consider doing some general troubleshooting and removing extra sticks of memory (try 1 stick of memory at a time in different slots), the hard drive, battery, and anything else you don't need just to make sure they aren't related to the problem (I would be sure to check into the memory more).
Anyway, hope this helps and good luck in getting your system up and running soon!
