PC not Posting

[throwawayskip100]

Hi Folks,

 

I have a brand new rig that I've built, but it has this weird issue where it doesn't start / post after shutdowns. I've tried two different PSU's and with the first one it would work after me unplugging the power cable to the computer and replugging it in, but with this new PSU it doesn't seem to work at all.

 

This PC ran fine yesterday, and I restarted it and shut it down multiple times, I'm not sure what happened today.

 

Here is what I have tried:

Two different PSU's

Resetting CMOS

 

Here are the specs:

 

Ryzen 7 2700X - CPU

Asus B450-F - MOBO

Corsair 16GB 3200Mhz Vengeance PRO RGB - RAM

Thermaltake TR2 RX 750W - PSU

ADATA SU650 120GB - SSD

 

Thanks

I had a similar issue to this when i upgraded my cpu it was working fine when i first installed it and when i restarted it then the next day it wasnt posting. Only thing i found that worked was re installing windows. Before doing this though i would check that everything is seated correctly as something may of just slipped slightly.

I can't even post, that is the problem.

Do you have a short somewhere,?

If this first time building make sure standoffs are in correct place

Try checking that everything is seated correctly

The standoffs should be fine.

I just doublechecked the seating, everything is in place.

 

I have also unplugged all the case fans to see if the PSU is the problem again, but it doesn't seem like it.

When everything failed - bench it

Start switching parts

Does it even power on?

Hi,

 

I'm not quite sure what you mean by does it power on?

 

The motherboard lights that are on the board do come on, so I know that the board is receiving power, I'm not quite sure if it is enough or what is happening.

 

I don't have any extra parts where I can drop them in, although I do know 1-2 parts that are 100% working, the SSD and GPU since I had them in my old build.

[Zeleath]

How many sticks of ram do you have? If 2 try just booting with one stick ive seen that, that sometimes works. 

[Artoo]

Since you checked the PSU already I'd suggest to check RAM/GPU with an older build (if you have compatible parts)

Connect everything out of the case and start benching.

Just make sure on what surface you are doing this so any accidents wont happen with mobo.

I would make sure motherboard is seated on stand offs and not touching case

The PSU was bad, I replaced it with another one and the system now works.
