Hello, i just completed building my new rig. When i turn it on, everything lights and turns on, after 10 seconds or less, computer shuts down and then powers up again, and so on... Keeps restarting, and if i put Signal speaker (shows that pc is on) it keeps beepinng all the time. Can it mean that some of my components are damaged? What should i do ? please help!

sounds like bad BIOS settings.
1) Do a hardware Bios reset (should be a button on high end boards or a jumper on lower end models), this will reset everything back to factory defaults... be sure to put the jumper back into the off position after doing this.
2) Next go into BIOS and find the option for 'load optimal defaults'. On a traditional Pheonix BIOS this is found right on the main page. On a newer UEFI setup you may have to poke around a bit to find it.

Hopefully that fixes it for ya!

that mobo does not exist. did you mean a z68 or z77?
Either one is going to have UEFI

Look in your motherboard manual for specific details. Between the watch battery and the front panel IO there should be 2 bare metal pegs which say "CLR_CMOS" (clear CMOS). Unplug your system from the wall and short these pegs together with a screwdriver or other metal object for ~20 seconds (if you have good hearing then you ought to be able to hear a high pitch whine as it discharges). After you are done then make sure that nothing touches these pegs together as it can cause issues (ie. make sure that there is not a jumper between them). This should reset everything to factory defaults and get you going in the right direction so that your system can at least POST (initialize).



If that does not work then it is time to try bread boarding your system:
This means taking everything out of your case and hooking up bare essentials on a table (making sure that your mobo is on an electrostatic bag or the packing foam pad it came with). Start out with only the monitor, mobo, 1 stick of ram, PSU and CPU. Short out the power switch header and see if it turns on (screwdriver is the tool of choice here).
If it works then turn it off, add the rest of your ram, and try again
If that works then add things like keyboard and mouse
Next add drives (HDDs, SSDs, and optical)
Lastly add the GPU

If everything works while out on the table, then it is time to take it all apart and build it in your box. More likely than not you will find that you accidentally had something hooked up wrong, or a rogue case screw shorting something out, but you may also find bad parts that need RMA.

THank you for helping me, I apreciate that. Again with the CLR_CMOS thing, i must touch the two pins with a screw driver and hold like that for 20 seconds? thank you!
