I have an Asus Maximus V Gene Motherboard and i5-3570k. The Asus Maximus V gene mobo comes with an overclocking utility in some of the free software called CPU level up for automated overclocking. I attempted an overclock to 4.2Ghz and ran some tests. The system appeared to be stable and I still had low temps so I jumped to 4.6Ghz and it would not start so I tried 4.4Ghz. It started but froze after about 10 minutes. Realizing the overclocking utility did not produce stable results and was not putting in correct settings I tried to set the CPU back to default in the BIOS. It booted up fine and I now have complete stability but now I have another problem. The overclocking utility also overclocks the iGPU and it ****ed up the BIOS settings so much that now I have another problem. Apparently the iGPU does not exist anymore. Upon rebooting one of my programs called Virtu MVP for optimizing iGPU and GPU synchronization immediately shut itself down and said the iGPU was not configured correctly and that a problem needs to be fixed. The computer no longer detects the iGPU. When I go into CPU-Z It only lists my nvidia card whereas before it listed the nvidia card and intel HD 4000 and in the overclocking utility it used to show iGPU frequency and voltage but anything to do with the iGPU no longer shows up. It doesn't even appear in the BIOS anymore. I thibk the stupid overclocking utility fried the iGPU or something because now it just doesn't appear anywhere. How can I fix this?
