Overclocking gone wrong

[SquintEastwood]

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

I'm pretty sure the extreme3 has a cmos battery. It also should have a CMOS jumper

There is a CMOS battery on that board, just right under the PCIE slot.

Also you can use the jumper to reset instead of using the battery:

So what exactly would I need to do?

Ah, my gpu was covering it  I don’t quite know what to do with it, can you help?

could you explain the jumper better? I can’t understand that too well, does it come on the motherboard or with it?

What if you don’t have a jumper, how else could you do it? 

There is a jumper cap on there, without it you won't be able to turn on.

Okay so I know how to do it but is there anything else I should do before I do it? Like remove a gpu or anything?

Will this only help if it is a bios problem? Could it be a dead board or cpu or just a bios problem?

Nope, you can leave everything else inside.

I reset it and it pulled up a fail to boot thing and let me click delete to go into the bios, now I’m in the bios and doing just fine  thank you so much for your help and for being so fast to reply, you are awesome and made my night. Right now I’m only gonna get 3 hours of sleep max tonight because I’ve been stressing so much about this dang computer but I’m so relieved that it fixed, thank you so much

You helped me so much because I would’ve never even known about that and would have been stressing this all day tomorrow and still would think I killed my board
