I really need help

[NeptunoIIVerger]

I just builded my first pc but I can't install windows 10 on it (usb) and now it doesn't even post!

It's a 990fxa gaming motherboard from msi (8350)

What can I do?

Try resetting the CMOS. There should be a couple of pins you can short on the board or sometimes even a button.

Does it give you a post code or anything?

Ok, so it was a problem with the usb and hen it worked but it only turned on sometimes (randomly), the other times the fans would spin but it didn't post and the times when it was working fine, the whole system was freezed (again randomly) I looked in the forums and a guy said to update the bios, so I was going to do that but now it doesn't turn on(never)

I think it was because of the cpu power; when I built it the psu manual said to only use a 4pin but the motherboard manual said to use a 8 pin, I tried to use the two 4 pins from the psu but it wouldn't work

Now I don't know what to do, I tried repositioning the cables over and over ( I took apart my build and put it in a test bench) but I doesn't post

My parts are

- FX 8350

-MSI 990FX GAMING motherboard

-Deepcool captain 120 CPU Cooler

-2x4 GB HiperX Savage 1866 MHz (for some reason, the bios and windows said 1600mhz)

-Seagate Barracuda 1 TB

-SiliconPower 120GB SSD

-ASUS RADEON R7 360( I ordered a msi 390x but it's on the way)

-Thermaltake Versa H21 Windowed

-EVGA NEX750B

-windows 10 pro

I did but it doesn't work, I want to know what part is failing : cup, ram , psu or mobo so I can use the warranty but I have no idea how to test that

try re-seating your cpu and ram, also see if unplugging your drives will get you into your bios.

its already without the drives, in a test bench

your motherboard needs 8pin power for the cpu.  your power supply has a 4pin that cpu on it, and i believe it has another 4pin that says cpu2. you need both plugged in.  they should both fit.

Just tried it, it still doesn't post, does it have something to do with voltages?

[NeptunoIIVerger]

in the manual it says this

[LabRat]

what power supply is it?

 

the 2 4pin.......... that was right. they only go in one way. no way to make a mistake.

[NeptunoIIVerger]

so what should i do?, i spent 1700 dollars on this pc( i bought monitor mouse, etc)

can you upload a picture of what you have built so far so we can see if there is anything wrong that we can spot ?

[NeptunoIIVerger]

here it is

[LabRat]

the water block......... did you install the insulators after putting the screws in?

[NeptunoIIVerger]

insulators?

[MadManMarsBar]

also you have the wrong power going into the CPU , you need to have BOTH on the CPU power connectors in the slot ( the ones with the all black cables )

im sorry but idont understad english that well, could you be so kind and clarify it?

[MadManMarsBar]

you should only need one cable from your power supply for the CPU power connector , not 2 cables

 

You could be able to power the Motherboard , CPU , and graphics card without plugging any more cables into your Power supply , 

 

you should have a cable coming from your Powersupply that has 4 black wires and 4 yellow wires with a blue line on it , use that cable for the CPU power and un-plug the extra cable you plugged into the power supply

All i can suggest is you take everything apart and start from scratch , make sure for things like the cooler to follow instructions

i just tried it , it doesn't work, something is already failing even though is new, i need to know what is it so i can ask for a replacement
