Hello. Sometimes after i overclock my memory from 1.2v to 1.25v my pc beeps. On short beep. The way i usually fix this is by reseting the bios by removing the lithium battery (cmos reset). But this time everything runs as it should be but i get no signal input. Only “No signal” from my monitor.
I have tried removing every component, changin the ram slots, cleaned the dust, double checked all the screws and cheking the cpu if it’s disturbed. But still nothing on the monitor. Any help?
Specs:
Asus z170 pro gaming
I7-6700k 4Ghz
Gtx 970 4 Gb
2x4Gb ddr4 2333 mhz

OK, try resetting the BIOS again. Here's the complete sequence.
1. Shut down, unplug from wall.
2. Open the case. Find the battery in its holder and be SURE you note which way it is supposed to be in there. (Any chance you got it backwards in previous work?) Putting it in backwards will make it fail to work. Also find near there the little set of 3 pins with a jumper on two of them, used for the Reset process.
3. Remove the battery. Move the jumper from the two pins it is on, to jump the other pin pair instead. Leave that on for 10-15 sec, them move the jumper back to "normal" position. Replace the battery right way in.
4. Close up, reconnect power, and boot into BIOS Setup. Proceed as my earlier post. If you still get no monitor feed...
Likely what has happened is that the BIOS Reset also set your mobo to use its on-board video chip for output, whereas your monitor is connected instead to your add-on video card. This can be fixed.

Before that, though, let me suggest a step you may have missed. Resetting the BIOS can solve some problems, but just removing and replacing the battery (and also using the Reset jumper - see manual p. 1-6) may not complete the job.To be more thorough, after this you should take an extra step. When you first boot up, go directly into BIOS Setup. If it is set to show you the EZ Mode screen (p. 2-7), use the F7 key to switch to Advanced Mode (p. 2-8). On the top menu bar click on Exit to reach the Exit Menu (p. 2-47). There choose the "Load Optimized Defaults" to load a complete set of stable settings. After that you will want to change some of the default settings before finishing. For example, you may want to adjust the Boot Priorities (p. 2-45). And as below, you will need to change video output device. After you have made all your configuration changes, remember to use the "Save Changes and Reset" item.

Now, back to your original problem. Assuming I am right, this will take two steps. First, shut down and move the cable feeding the signal to your monitor from the video card output connector to the output from your mobo on its back panel. This will ensure that the signal from that system gets to your monitor so you can see it. Now boot up and go directly into BIOS Setup by holding down the "Del" key. This should give you a display you can use on the monitor. Now, make the changes you need in BIOS Setup. As I said, I suggest you Load Optimized Defaults, but that's up to you. Set your Boot Priorities. Then go to the Advanced Mode menu and choose the Advanced option from the top menu bar (p. 2-27). See manual p.2-29 under System Agent Configuration, Primary Display. Set this to the video card location - I expect it will be in a PCIe slot. Back out and use the Exit menu to Save Changes and Reset. This will save your settings and reboot. Now move the cable to your monitor back to the video card output connector, and you should be seeing the display there as it was before.

4. Close up, reconnect power, and boot into BIOS Setup. Proceed as my earlier post. If you still get no monitor feed from either of the video outputs, we have a different problem.

By the way, I failed to suggest one other thing to check. Make sure the controls on the monitor are set to display the correct input signal.
 
Solution
I have tried placing a screwdriver between the clrtc pins, i only have 2. I did that eith the battery removed. I don’t know if i’ve done something wrong but there is no signal
 
That was the correct way to Clear the BIOS. You did nothing wrong there.

In reading your manual I note also that, close to that set of 2 pins, there is a 3-pin set with a jumper on Pins 1-2, labeled "CPU OV". To enable certain settings of over-voltage for the CPU for overclocking, you move the jumper to Pins 2-3. Did you do that in your overclocking moves? If so, check whether you have returned the jumper to the default position 1-2. Of you change that, be sure to shut down and reboot to allow the system to reset default CPU parameters.
 
I once had a truck. I stopped in a parking lot and tunred off the engine. When I tried to restart it, it didn't make a single noise. Not a click. So I popped the hood and beat the engine block with a wrench (I was pissed because my wife was going into labor and needed to get home). After beating the engine furiously, I turned the key and it started right up. Have you tried beating it with a wrench?
