So I have built 2 PCs in the last 10 years, I'm not mega knowledgeable but my friend asked me to help him build nice gaming PC like mine. He lives like 4 hours away so we decided to do it via messenger and camera and I'd walk him through it step by step. Took a few hours but we got there and when we tested to turn the power on, the only thing that seems to be getting power is the motherboard.

No case Fans are spinning, No fans from the GFX card are spinning, No Leds from the case are lighting up.

It's tough as I'm not there in person and I tried to troubleshoot it with him for about an hour.

I made sure the POWER_SW was on the right pins and orientation, we triple checked all the cabling was plugged in. I'm all out of ideas what the issue could be
When we switch the PC on the motherboard lights up but thats it.

His specs are as follows:

Sama Ark Full Tower Gaming Case
b150 ASUS Pro Gaming motherboard
EVGA Nvidia Geforce Gtx 1080ti
Intel Core i7 (i7-8700 LGA1151)
Viper Patriot DDR4 - 8GB Ram (4x2GB)
Corsair RM 650 Watt PSU
Hyper 212 Turbo CPU cooler

Any Help/Advice/Troubleshooting Steps would be appreciated

Thanks

What i7 is it?
What specific RAM is it? There's loads of 2x8GB kits from Viper.

You're going to want to remove everything and boot with only CPU+RAM. So put the motherboard on the motherboard box, install the CPU + CPU cooler, then put in one stick of RAM. Connect the CPU + Mobo power from PSU, then turn the system on by bridging the 2 pwr_sw pins with a screwdriver. If the system doesn't POST, try the other stick of RAM. If it still doesn't POST, then you know CPU, Mobo, or PSU are the issue and one of them is potentially dead.

Thanks for the reply.

The Ram Sticks are:
Patriot Memory Viper Elite 8GB (2x4GB) DDR4 8GB DDR4 2400MHz memory module

The i7 Is Intel Core i7-8700 LGA1151

When Looking at online troubleshooting, They also mentioned to try to boot with only 1 Ram Stick.
So I will definately try this.

My friend has gone to bed for work in the morning, but this is the first thing we will try.
We will then try your suggestion of Taking everything off that isn't needed to boot and boot with only CPU+ RAM. I'll also try using both ram sticks and only 1 at a time.

I will post back with an update when my friends back from work and we can try these steps.

Thanks for the help

CPU is not compatible with the motherboard. i7-8700 is Coffee Lake(8th gen), and only compatible with 300 series Intel motherboards, so H310, B360, H370, and Z370 for now. 100 and 200 series Intel chipsets are for Skylake and Kaby Lake(6th and 7th gen).

I guess I overlooked that.

I checked the Processor Socket of the Asus B150 motherboard which is 1151
and the i7 is an LGA1151 but that doesn't work together?

What i7's Do I need to be looking at then compatibility wise?

To be honest I'd rather get a 300 series motherboard then compatible with the 8th gen i7,
would be cheaper for him.
Albeit annoying to reinstall everything.

i7-6700 or i7-7700 would make most sense in a B150 motherboard since you can't overclock. Though if he already has the i7-8700, it'd make more sense to return the motherboard and get an H310 or B360/H370 motherboard since the 8700 has 2 more cores than the 6700 and 7700.

It's common knowledge that building your own PC brings lots of unnecessary risk.

Make sure to backup your data with a 16GB Sandisk Cruzer Blade USB flash drive for only £9! Remember, that's ASDA price!
