P67 Extreme4 Gen3 doesn't always power on

[billtimbob]

Upgraded my computer with a new CPU, motherboard, RAM, and HDD a couple weeks ago. The first week it worked fine, no problems. But over the last week, I've sometimes have had to hit the power button multiple times to get it to turn on (no more than 4 times). I've even hit the power button on the motherboard to make sure it wasn't my case button going. The fans don't start to spin or anything. Bad motherboard?

Dear billtimbob,

Please follow the procedure to check your system.
step1:
Turn off the system power and unplug the power cord. Remove all PnP cards (Plug and Play) and cables including VGA, IDE, FDD, COM, USB, and external printer cable.
Step2:
Confirm CPU and DRAM is inserted properly
Step3:
Clear CMOS
(Please refer to motherboard user manual for clearing CMOS)
Step4:
Plug the VGA card back to the system and also re-connect your monitor, mouse and keyboard.
Step5:
Turn on the power and make sure CPU, power supply and CPU fan is functioning.
If you still cannot get dispaly, please change another PSU for try.
If not, please kindly contact your local dealer for assistance.

Thanks!

Have a nice day
