Recently built my first computer, MOBO- Asrock Z170 PRO 4 i use windows 10 and i've been getting many errors with that.. including BIOS and MEMORY MANAGEMENT errors. My computer will work on day, and i have opened it up to make sure everything is secure and not loose. But now it just refuses to turn on at all, i know it's not my monitor because i have tried using my other monitor and it's the same result.

This is quite stressful for me, and i'm extremely new with computer building and what not.

Any help is extremely appreciated
!

I take it you're not even getting a P.O.S.T. screen.
After checking all modules and graphics card are seated correctly;

1.Disconnect everything that's not necessary, wi-fi adaptors, external drives etc and try again several times.
2.Remove all but one memory module and try again.
3.If still no luck, swap memory module with another.
4. If still no luck, remove hdd/ssd and try for post screen again.

Try booting off the internal GPU. If that works the problem lies with the GPU outputting to a display
If that dose not work, if you have a spare CPu, put that it
I know you said it's not ur monitor and this might sound abused but repeat the above on your TV

- If all the above dose not work....check the cable maybe?
