[SOLVED] PC turns on and shuts off immediately.

[sybrscr1ber]

Hey guys,

 

I need some new input.

 

Well, the title is pretty self-explanatory. My PC wouldn't start, it turns on and shuts off immediately.

 

What happened the night before: for some reason arch linux went sleep and I couldn't wake it up so I kill-switched it with PSU on-off switch (don't think that's the cause or is it?), so the morning I push the start button and voila, it won't start.

 

PSU makes a "click" sound, Q code shows 00 and the it shuts down.

 

Narrowed down to 3 parts: MOBO, CPU and RAM. Everything else is literally unplugged.

 

The PSU tested on my other PC, works just fine.

Visually inspected MOBO, looks normal.

No smell.

Checked for loose cables.

 

SPECS:

 

ASUS ROG STRIX X299-E GAMING

Intel i9 7900x

GSKILL 8*8GB Trident Z RGB 3200Mhz

850 EVGA G3 GOLD

 

 

SOLVED

What I did was remove the CMOS battery and followed the "Clear RTC RAM" instructions.

Is the PSU set to the correct voltage (110V/220V)?

[sybrscr1ber]

I don't know. Doesn't it set it automatically?

My friend had the same thing in the past. His PC won't start and after pushing the on button, it just make a click sound and after that restarts itself but then also click and goes back to restart. Not able to proceed into windows at all.

 

He changed the PSU and everything is working again. Maybe you can use another PSU to see if it works on your PC since you mentioned you have another PC.

Just tried my other PSU (Seasonic G-750) on this rig, nothing happened, same thing.

 

Plugged it to the MOBO, CPU and GPU.

00 is no cpu detected. Can be PSU or RAM causing it to fail to boot, but most often is a bent pin from install of the CPU from fan/heatsink etc.

 

Did you build it yourself, or buy from a store?

 

But, as you said, it failed from a shut down to cold boot? Hmmm... was it overclocked? Hopefully you just need to reset the bios!

Myself. Couple weeks ago.

[sybrscr1ber]

I've got 8 ram sticks and I tried each and every one in C1 slot. Nothing.

Try a bios reset! (ROG has a one button option on back? )

You're talking about BIOS Flashback button. AFAIK it's for updating bios without actual booting. This MOBO's got "clear CMOS" jumper. I can short-circuit the pins.

[sybrscr1ber]

After short-circuiting the "clear CMOS" jumpers something weird started happening.

 

[TechyBen]

The i7 has no integrated graphics? Do you need a GPU to boot? However, it does sound unhappy.

 

Could be PSU/Motherboard/RAM/CPU.

Tested PSU and 8 sticks of RAM from this rig on my other z170-based rig. It works just fine.

I don't think so.

 

So looks like it narrows down to Motherboard or CPU.

 

What should I do?

[TechyBen]

Without a GPU, how will you know it boots?
