My PC keeps crashing!

[TMobile]

Hey there!

 

I have been getting some crashes and there are a few things that might be causing it, because I upgraded these a month ago and it just started a few days ago. before the upgrade I had no problems:

-I have Cablemod Cables could one of them be faulty or have a loose connection?

-Rtx 2070 (drivers)?

-RAM (had this since the beginning) crashed at 3000mhz so I use DOCP and 2933mhz (used to be stable, less chrashes when I run at stock (2133mhz).

-Anker usb hub (how? idk)

 

my other specs are: r5 2600, asus strix b450-f, gigabyte rtx 2070 windforce, 16gb gskill trident z rgb (2x8 3000mzh (running atm at 2133)), cryorig h7, seasonic focus plus gold 650W.

 

What happens: sometimes (really really irregular) my pc shuts down, and immediatly starts up, so basically goes to windows log in. Other times my keyboard will lose power, and my monither will lose signal (just black). I then have to flip the psu switchm, as the power button doesn't do anything, and wait for the system to "drain". only then I can restart it.

 

I really have no clue what is causing this, but I think it is something with either psu, cables or ram.

 

Also I use asus aura for my motherboard and rgb fusion for the gpu, however sometimes rgb fusion just turns on for a brief moment in the taskbar, my system lags alot and my ram lights go of to turn on again after half a second (to the same coour). Could this also have anything to do with my problem?

 

Any help would be appreciated.
