Where can I download the Recovery Image for an ASUS GL 553?

My ASUS GL553 died on me after 4 years of working perfectly. It would not boot from any device, however, it logs into BIOS with no problem.
Right after the ASUS logo appears, the computers shuts down completly, no error message, it just powers off.
I removed all the devices, trying to pin point the culprit, HD, SSD, RAM (switched with diffrent bays and Dimms), Battery... same thing.

At this point I believe the problem comes from the motherboard or maybe even de processor. Replacing it its not a viable option.

I'd like to use the HD as an external storage unit, but I'd like to keep the recovery partition around just in case I manage to bring the laptop back to life

Thanks!
