I recently built my first custom pc and installed windows but there was one problem it randomly restarts or shutdown and if it shutdowns I cant turn it back on the only way to turn it back on is to turn of the psu and turn it back on but the strange thing is when it shutdown all the rgb on my fans and ram are still on, normally if I shut down this computer all the lights turn off.
 
Im running on windows 10 pro without a key
using a ASUS 470x pro motheerboard
Using a MSI 1050 ti 4gb graphics card
 
I have all the part list just reply if you need them.
 
Thank you

Try the power supply first, that fault as described matches with a PS failure.

The power supply isn't hot when this happens and it is an corsair HX750I

and it seems like it isn't broken because it supply power the only thing i turn the PSU off is because i want to fully shutdown then i can turn it back on

As has been said, the symptoms you describe fit best with a PSU fault, a problem with one of the several output voltages could trigger that behavior, and leave the system partially active. Although the PSU could be tested using a digital multimeter or a PSU testing jig, a momentary loss of voltage that could cause this would not necessarily show up on a meter, so trying a known good PSU is the best test.

 

The alternative to considering the PSU is to test or replace every other part in the system, then if they all prove OK, you'd have to decide it was the PSU all along. Since the PSU is one of the easiest parts to borrow a substitute to try, that is the least trouble to eliminate first up. It has nothing to do with the PSU being hot, or any aspect of its brand of manufacture.

That's one of the curious things with this failure.  It locks up or fails to return from sleep or hibernate mode and a forced shutdown is needed to power off.  Even then it won't restart again.  Powering off the power supply from the rear panel, if it has one, or removing the AC power cord to achieve a successful boot, points to the power supply failing, usually the the five volts is the culprit as the fans and drives still spin but nothing else responds.

I read the OP's description as the fan illumination and RAM active LED are still on, rather than fans themselves running (or drives), but the description is not so precise.

When the system randomly shuts down all the RGB and the ram RGB lights are all turned on and the gpu lights are on too and the hard drive is still running.

with my eyes I cant see any difference but my monitor saying display port no signal.

 

But when I shut down the computer normally everything turns off . 

Before I thought maybe my GPU is broken but that doesn't answer why it restarts.

Is there any software I should download and record the power status and post the information here?
 

Could this have happen due to system crash?

Are you sure it is not going to sleep?  Some motherboards default to not wake on USB so the only way to wake it would usually be with the case power button.  It could also be that some driver or hardware item is causing it to crash when attempting to sleep and therefore leaving it unable to wake again.  You could try disabling sleep mode in the Windows power settings.
