I overclocked my i5 4690k And had a decent overclocking at 4.5 that was stable and didn’t get over 75 degrees, I stress tested it for a while and it looked stable. Restarted and went into the bios to change a timing, and ever since it has failed to boot, it will load into motherboard splash screen, will even show the F2 for bios and all, and sometimes nothing, and sometimes it will say with the Asrock splash screen “Preparing Automatic Repair”. In every situation it is just frozen, I have to hold down the power button to get it to go off, the reset button works but it just goes back into another splash screen or black screen. I took out the ram removed dust reseated it, I don’t think it has a cmos battery and in that case how could I reset bios and would that even help? Please help I’m broke and can’t afford to replace it which at this point it doesn’t look like it will end too well, but I’m open to advice Motherboard is Asrock z97 extreme3
