First of all as soon as i plug the power in all the fans and lights turns on, but it does not boot. when i hit the boot button the system does not boot, the CPU light constantly flashes, and sometimes the cpu fan turns on and the HDD spins. There of course isnt any OS on it and I've never seen it display anything. I've tried pretty much all trouble shooting techniques:
removed all by one ram stick
removed and checked cpu and heat sink
removed every component but the CPU, Ram, mobo and power supply
checked all the pins for damage
There is also no beeps from the pc speaker. I'd realy not like to call in a pro.
The ASUS P8Z68-V doesn't have a 'speaker' unless your case has one built-in. IF the CPU light is flashing most of the time it indicates that you either forgot to connect the 8-pin CPU power to the MOBO or the HSF is improperly installed -- it can mean a bad PSU or CPU or bent CPU pins.
Q - What HSF? (CPU Fan) e.g. Stock or something else? ; provide a link
Yeah I've added my own speaker for troubleshooting. I'll take off the CPU again and have a good inspection. I've connected a 4 pin power supply to the CPU because I believe it can run on just 4 pins according to what i read in the manual but I could be wrong.
I'm actually realy not sure, what happens when it POSTs, by the way I didn't have a 8 pin so I tried a 6, didnt have the same issue of turning on straight away without the power button but it didn't do anything. Probably hints towards that there is a problem with not enough power to the CPU.
IF the 8-pin had 4-pins pre-'capped' then I'd say make sure your PSU was ATX12V 2.0 compliant. ASUS puts blatant stuff like 4-pin/8-pin which can mean an 8-pin that is 4-pin + 4-pin which most CPU Power are (split).
There are 4-pin to 8-pin adapters, but I really don't recommend them or any cheap PSU. Get a good Corsair or SeaSonic PSU that is sized properly or over-sized (too small = bad, too big = fine) you cannot have too large a PSU and cause an issue.
Because most 4-pin PSU's are not ATX12V 2.0 compliant, and your MOBO specifies the 2.0; see - http://en.wikipedia.org/wiki/ATX#ATX12V_2.x I only use 2.3 compliant PSU's and those only with Japanese capacitors, Bronze or higher rating, and most importantly a PSU MUST have PFC (Power Factor Correction) plus current & voltage protection, and short circuit protection.
A cheap PSU gets costly very quickly when it takes-out your: CPU, GPU(s), MOBO, RAM, Drives -- you name it attached to it when (not if) it fails - in 10 seconds or less.
I've been learned Big-Time! $40 saved/cheap = $600 on two systems and within 30 days. Then I boned-up on PSU's and since I'm very picky!
david it not the memory or the cpu it the bios one the mb. http://www.asus.com/Motherboards/Intel_Socket_1155/P8Z6...
the stock bios wont boot with an ib cpu till you have the newest bios per asus web page.
if you bought the mb from micro center or a local store see if they can with a sb chip flash the bios for you.
if the mb had a flash back like my sabertooth i could tell you to boot off a usb stick and flash the mb to the newest bios..you can try and email asus and ask if im right that the mb wont post. if that is the issue all i can say is swap it for the same model but the 7x chipset or see if asus can flash the mb for you and send it back.
