New computer suddenly balnk

[Natedawg101]

I built a brand new computer and had it running fine for about 1 month then all of a sudden the screen goes blank and wont turn on. I have tested the monitor on another PC and it works fine but this one just wont. If you have any suggestions on how to fix this please let me know. SYSTEM SPECS: i3-6100, ASRock H110M-HDS, 8GB RAM, Radeon Rx 480 Dual, EVGA 430W PSU, 256GB ssd. (One thing I forgot to mention before was that the new motherboard ports don't work so im using the gpu one).

Does it POST?

Why is this in forum information? Try the computer without the GPU installed.

Ok does the PC have any sign of life it odd that it would just die are all parts new when you press on button does CPU fan move.

can you try shorting two power pins on mobo to see if it case button (if you don't know what your doing don't do it

The pc turns on but does not post, and yes I have tried that.

is your psu a 24 pin or 20 pin???

people say that you can plug a 20 pin psu into a 24 pin mobo but you will break the mobo doing this.

the pin outs are not the same.

also this mobo has whats called fast boot with uefi restart feature so this could be an issue.

pull gpu, ram, and cpu

power mobo on.  does board beep? yes put cpu back in and power on, beeps? yes then put ram(1 stick at time) in and boot.

you may have dead ram stick.

i still feel that ddr is misnomer as most think of it as double channel but its actually a dual data rate which means it has 2 gears in it transmission, low and high

24 pin is the same, I have a computer like that. 24 pin is actually 20+4 pin.

[bcguru9384]

then why do pin out charts say different? 

do search for psu pinout then see images

they are different

[bcguru9384]

the 5volt pin (17) is a neg 5 on 20 pin while its +5 on 24 pin

that is big deal

small difference big effect

[bcguru9384]

since 24 pin does not use this pin cut the wire on your 20 pin then it will not ghost draw or vampire suck at the mobo

you could always take usb cable and cut end off one side and twist the usb +5vdc wire to the now free -5vdc 20pin wire and attach usb ground dc wire to a common wire on the 20pin so psu will be happy and get its full power

[bcguru9384]

the purpose of the minus 5vdc wire is so psu can regulate the systems voltage rail. basicly it is a voltmeter for psu. 

24 pin psu sense this info internally in the psu

this why i say to use the usb so that psu has its meter back
