New Build Doesn't Boot :(

Indigo · 19 Jan 2016 at 23:25

Built a new PC using a couple of donated parts from my brother (CPU / Mobo) which were working fine before he upgraded and everything else was new.

CPU is a 2500K
Motherboard is a GA-Z67XP-UD4
Using onboard graphics.

When turning it on the CPU fan comes on and the phase LED's do as well but then nothing else happens.

Any ideas?

Double checked all the cables?
Tried with 1 stock of ram/reseating it?

I had an issue with a buddies 2500k when using on board in that you need to install drivers to get digital signal. Are you trying to boot using hdmi or dvi? If so try VGA.

Checked all the cables and seem to be ok. Tried without ram, with 1 stick, different slots etc.

Motherboard only has an HDMI output and was going to go with onboard.

What do you mean by digital drivers?

I've taken out the battery too but nothing happened.

CMOS reset?

Indigo · 19 Jan 2016 at 23:53

Tried resetting but doesn't do anything either. Going to take the battery out again for a while and come back to it later.

Battery taken out, still nothing. Just the CPU fan spinning, no beeps, no response. Pffft

Try 1 ram stick at a time.

djshauny1 · 20 Jan 2016 at 01:10

Do you have both power leads plugged in ?

ExRayTed · 20 Jan 2016 at 01:11

No beeps - is the mobo speaker connected?

The only other thing I can think to add is to try the build outside the case.

The most important question is.... Which power supply are you using ? model number , make and watts.

A poor quality PSU will cause POST issues and the pc will never start up or even show beep codes or digit codes if the motherboard has that. The fans may all start up and nothing happens, but may seem like the pc is powered up but in reality it will never start because it has failed to get the right power. Also have you made sure to connect the CPU power near the cpu not just the 24 pin motherboard cable.

PSU is a Seasonic G Series 550W Gold Series.

Power cables are plugged in near the CPU and the 24 pin directly into the motherboard. A third cable is going to my SSD via Sata and then left all the others out as not using a dedicated GPU at the moment.

i had similar issue, turned out the main mobo power cable had been knocked out.

Indigo · 20 Jan 2016 at 10:48

Although not ideal I'm guessing but would a 350W PSU be enough to power a 2500K, Z68 Motherboard, SSD and 8GB Ram?

Can use the PSU in my old computer to test but obviously don't want to underpower it and cause problems.

Biz.Kid09 · 20 Jan 2016 at 10:55

350w will be fine, what PSU is it out of interest? (your old one)

Indigo · 20 Jan 2016 at 10:59

Just a Corsair Value 350. Sonot the best but does a good job in my current PC.

Can you confirm what motherboard you have?

Could only find GA-Z68XP-UD4 and that has no onboard GPU ports.

Indigo · 20 Jan 2016 at 11:58

Ah sorry. It is the ZA-Z68XP-UD4.

It has onboard HDMI, the 2500K has built in GPU/Graphics does it not?

russell664 · 20 Jan 2016 at 12:48

Did you re-seat the CPU during the upgrade? Just thinking if the CPU was taken out, you could have accidentally bent some pins in the process.

Indigo · 20 Jan 2016 at 13:38

CPU was reseated and thermal paste reapplied.

Had a look and nothing looks bent but with so many pins I'm not sure how obvious it would be if any were.

Sorry. the board i found was the B3 version, with no HDMI.

Is this connected to a monitor or a TV?

Reason i ask is, i built a AMD FM2 PC connected to a TV via HDMI and it would not show bios (Windows worked ok).

Was fine on a monitor though.
