I purchased this used ASUS G750Jm at a cheap price because the owner messed up its BIOS. I had to recover it through USB flash, and it works just fine. However, the issue that i face is random 100% CPU + GPU fans, no Nvidia Card detection, Intel(R) Xeon(R) processor E3-1200 v3/4th Gen Core processor PCI Express x16 Controller - 0C01: An ACPI Power Object failed to transition state driver problem. I have read multiple posts on the internet but no one seemed to have found a fix to the problem. Is it a hardware issue? will changing the GPU fix it? Kindly, any help would be greatly appreciated!
