Hi All,

kinda desprate here, hope some one can help.

motherboard model Asrock Z68M-ITX/MX, i5 2500k CPU, corsair 8gb ram

motherboard powers on, cpu fan starts spinning. after 8-10sec it powers down and powers back again after 3-4 sec.
the cycle keeps repeating endlessly. mobo does not have speaker out so can't get any beep codes.

investigated so far

1. psu, used various other PSU's with same result.
2. CMOS cleared as per procedure described in mobo manual.
3. RAM changed and verified on other systems. same result.
4. changed BIOS chip. but no luck. same issue even after bios chip change.

any help or pointers to resolve the issue will be appriciated.

Hi,

1. Try to reset the CMOS (10-Cent-Method):

Please note: while testing, you should remove all unnecessary additional hardware components from your PC (not on Laptops)!
You only need: 1 CPU, 1 RAM 1 Graphic adapter, Power supply unit + mainboard.
No CD- and HDD drives! No USB-Sticks! No TV-, Sound-, and other Controller cards, etc.!
Connect USB Mouse and USB Keyboard only on USB2.0 ports! Don't use USB3.0!

If all this does not work, then the motherboard itself could be defective or some other connected hardware components prevents the PC to boot up.


Best regards
