PC not turing on after randomly shutting down

[Rustys]

Try a different PSU.

Forgot to mention that I tested the PSU and it worked fine

Tested how?

Please tell me you did not use that useless paper clip test?

Wish that they would STOP suggesting that useless test.

Bad PSUs can pass the paperclip test. The true test that eliminates a PSU from the equation is a replacement or trying that same PSU in another known working machine. Only these 2 can truly rule out a PSU.

Paperclip tests are flawed since you’re advised to induce a load on one end of the PSU to get it to start, that test does not tell you how many watts the PSU can effectively output if connected to a full build.

I did the paper clip test

I did the paper clip test

I can test it in another machine I have, if it supports the wattage

I teste it in another PC, the PSU is not the problem

Had the same thing happen to me once and it turned out to the motherboard.
Fans and the power light came on, yet nothing happened.

You can assemble the system outside of the case and see if the same results happen.

Might also try reseating data and power cables see if to make sure that they are correctly connected.

Did you try they PSU from that system and see if it preformed the same?

Test the RAM stick(s) one at a time see if that makes a difference.

Sorry but you have post on a tech forum asking for help but have provided zero information about your computer or it`s hardware, this makes it impossible for anyone to even hazard a guess as to what is going on.

Is the computer a custom build or brand name such as Dell or HP, if a brand name, provide the model name or series number (not serial)
if a custom build post the brand and model name or number for the
CPU
Motherboard
RAM (including the amount) and number of sticks.
Add on video card if one is used.
PSU (power supply unit) providing these details will enable folk to better help you.

I did the ram trick, still no life. Although we have slightly different problems, my pc doesn’t turn in at all. Only indication of like is a little green light on the motherboard.

The cpu is an amd with 8 core and 8 threads am3 mount, I can’t find the specific model.

The motherboard is an Asus M5A78L-M/USB3 ll Solid State DDR3/AM3/AM3+ FX 78 Motherboard

The PSU is a LSV Ultra 450W ATX power supply

The GPU is an NVIDIA GeForce GT 1030

The ram are 2 Hyper Blu Kingston ddr3 8GB stick, in total 16 GB

try the other ps in this computer

Because you do not know the cpu we do not know if it has onboard graphics.
Remove the graphics card -test

I’ll give that a go

try the other ps in this computer

I found out that it’s the ATX12V slot, for the 4 pin yellow and black wire thing to go in

Forgot to mention it turn on when u press the power button, but the hard drive makes a noise

Also forgot to mention that it only makes noise with the 450W, the other PSU is I think a 265W

Screw that, the beep is coming from the mother board

[veeg]

Is that a short beep or a long beep ? This noise coming from the hdd, can you describe the noise?

[TheFerretRanch]

It’s one loud continuous beep, it’s not coming from the HDD, I removed the hard drive and the motherboard made that noise.
