Ok so my pc was running Fine and I decide I want to apply a light over lock to my core i9 I apply the Asus 5g profile press f10 and then I wind back up in the bios because apparently now I have no devices to boot from and one check in the boot tab confirms this. My ssds appear in the bios as they should but not in the boot menu. I remember this happened before and I called Asus and they fixed it but currently it is very hard to reach them due to COVID 19. Does anyone have any idea how or why this happened and how to fix/avoid it?

You may have to use Legacy mode to reach a SSD. Depends if you formatted that SSD in Legacy mode. ( Legacy = not UEFI )

Exactly how did you do this?

Generally this is because the OC didn't take.


Looking up your CPU specs....you have a base clock of 3.6ghz and a boost clock to 5.0ghz. Using the Asus 5G OC profile is not really OC'ing. You can achieve the 5ghz speed just by changing your power plan from balanced to high performance with in windows power settings. That will set your CPU to 5ghz.

You need to absolutely sure you have a very good CPU cooler.

Go back into the BIOS and turn off that Aaus 5G profile and see it will boot up.

Yes.....don't OC if you can't afford to replace said hardware. In the real world environment there is no necessity to OC a CPU. Other than you can or bragging rights or bench testing.

Do the following;
1 Remove the pw cord from the pw supply
2 Clear cmos or as asus calls it RTC. Almost all modern boards do not use the three pins and a jumper; they use two pins you momentarily short with a metallic object ie small screwdriver or whatever. Read your manual as to the location of the RTC pins
3 Once you have cleared cmos/RTC, replace the pw cord and pw ON. Enter the bios and make any custom settings you need ie ram speed, etc. Be sure the first boot device is windows boot mgr. Save settings and restart
The system should now boot normally. If it does not, you are going to either have to repair the boot sector OR just clean install windows.

I have a saying; "Do not overclock with parts you cannot afford to replace" As long as you do not mind frying parts, then you can attempt to overclock the system. IMO auto overclocking is less than useless. ALL overclocking should be done manually in the bios then tested for stability.
