I just built a new computer for a friend and it doesnt give me a signal. Its not my first time, but really, I have no idea whats going on.

Asus Prime B250M-K (Bios 0809)
i3 7100
Corsair valueselect ddr4
Zotac gtx 1060 3gb
PSU Tooq. 650W Ecopower II

Please, I need to fix this.
 
I understand you've built machines before, but since you've not specified what, if any, troubleshooting steps you've taken, my first suggestion is review the checklist about no display issues (click link in my signature). Once you've checked every step, post back with results/observations. I strongly recommend using the checklist as your template in your reply, just so others can be sure you've checked the basics and not omitting any results of your checks.

Also might want to post the PSU being used in this build.
 
What is the beep pattern you hear at power on?
The absence of display with and without GPU suggests RAM, CPU, PSU, or mobo; or any combination of those parts.

Have you tried the CPU on another mobo to ensure it isn't DOA?
Have you tried the RAM on another mobo?
have you tried the PSU with another build?
Have you tried another CPU, RAM, and/or PSU with the Asus mobo?
 
Everything starts spinnin and the lights turn on. I hear the hard drive spinning and thats it.
I tried removing the RAM and the beeper sounded. Put the ram back and went quiet.

I sadly have no other compatible parts to test with.
 
I'd start at the psu and chase down every single connection. With new equipment, many times (especially with sub-grade psus) the pins inside the the connector itself can either back out of the slot or are slightly mishappen and a real bear to get seated correctly. This mainly happens with the 20+4 mains and the secondary EPS. Not having either/both fully and completely seated will not allow the cpu to engage, and you'll get nothing beyond basic power line stuff starting like the leds, fans, hdds etc.
 
Tooq. 650W Ecopower II

Has two +12v rails rated at 18 amps or 216 watts each on the +12v line.
It is questionable if combined that the power supply can meet the 400 watt minimum power requirements for the video card. You might think about using better hardware.
 


Without being able to exclude part failure, I don't know that there is anything else you can do troubleshoot. The RAM test you performed, at least, rules out bad DIMM slots on mobo. I haven't looked up the mobo, but does that Asus board have the Mem Ok button? If so, have you pressed it?

Have you checked the mobo QVL to ensure part compatibility?

 

The PSU is not great, I agree, but it is what my friend bought and I would expect that, brand new, could at least power the computer without the graphics card.
 


No, it doesnt have that button and no, the memory is not in the QVL
