New Prebuilt Build No Signal (not even BIOS)

[TechManMax]

From Dr Memory on eBay (Trusted UK seller and they manufacture their own parts under the Xum brand and have very positive reviews) so currently waiting to hear back from them (won’t be before Monday unfortunately).

But…I’ve tried everything. The computer physically boots and the case fans and the CPU cooler fans (Thermalright Peerless Assassin 120 SE) work fine. I’ve tried swapping out the preinstalled Xum Ram (2x 16GB 3200 DDR4 CL22) for the Corsair CL16 3200 2x 16GB that I bought separately on Amazon and the no signal issue remains. I’ve tried unplugging and reseating the GPU (Palit Dual RTX 4070 Super) and still no signal. It’s of note that when I start the computer I can see all the case fans working, the CPU cooler fans (for the i7 13700KF so no integrated graphics to test) working, but the GPU fans are NOT spinning at all (though according to google this isn’t unusual on modern GPUs because they only start spinning past a certain temperature apparently?)

I have no idea what’s wrong. I get the single “Beep” sound when I turn it on, but no signal. No BIOS. Nothing. Apparently sometimes people get beep errors indicating different issues but I’m not getting any of those just the usual singular “Beep” when I press the power button. I’ve tried all 3 display ports on the GPU, as well as the HDMI port. I’ve tried on both LG C2 TV (HDMI) as well as 1080p monitor (DisplayPort AND HDMI). No signal. Both displays work fine with other devices.

Motherboard is ASRock B760M-HDV/M.2 D4

What is wrong?

The fans of the GPU must get spinning upon boot and stop spinning after Windows launch . At least my card is doing so . The brand of the GPU has failure rate not bigger than Asus .

Your mobo is not the right fit for the CPU .5+1+1 phases for i7 13700KF , bad .

The GPU fans don’t spin at all. The other fans are spinning fine. As for CPU compatibility this was a prebuilt machine from a trusted UK company and the motherboard lists the CPU as a supported CPU on all bios versions.

I would speak with the ebay seller.
You can send them a message.
Let them know what's going on, link this thread of you want.

I would remove the Graphics Card and RAM. Then power on the PC. You should get error LEDs or audible errors. Which is a good indication it's is working as intended. Then can repeat the RAM and GPU and connect any required GPU Power Connectors, then connect 1x Display to either HDMI or DP on the GPU card and power on the PC and go from there and see.

Intel CPU that ends in KF does not have an onboard GPU so ensure you connect Display to GPU card, not the Motherboard

Might try with an old card if it ll not void the warranty . The CPU will work but not at full . It ll be limited with 99% certainty

What do you mean not at full? The CPU is listed as compatible on their support page, and even lists 125W (which is the same as the actual CPU)…I hope I haven’t been conned here because it mentions nothing about power limitations. Also the PSU in this machine is 850W.

As for trying a different GPU unfortunately I don’t have one. This is a whole new build. Just trying to figure out why it’s not even booting into BIOS (or if it is why I can’t see anything). Machine is physically ON.

I have reseated both the RAM and GPU (even tried different RAM though can’t try a new GPU as I don’t have one), I’ve unplugged and replugged the PCIe connectors into the GPU and yes I’ve tried all display ports and the HDMI port on the GPU itself, not the motherboard as I have a 13700KF (no integrated graphics). Not even getting to BIOS.

The CPU is 125W only at the base speed . Intel shinanigans . Pl2 is 253W .That mobo is unlikely to deliver such power with 5 dedicated phases . Nevertheless , it wont prevent the PC from booting .

So…even if it was working…how power limited are we talking? And how would this affect gaming? Because if this does need replacing it’ll be a decision between replacement and refunding. I mean…there was no mention of power limits. That’s kinda worrying Ngl.

i7-13700kf probably pulls about 245w at full turbo power under an intense or artificial load. 125w is base clock speeds. Probably won't get past 180w during gaming depending on various factors.

Mainboard might not have diagnostic lights.

The gpu fan should spin for a few seconds at start up then stop. Might be some exceptions?

In the monitors menu see if the right video port input source is selected. Like hdmi, vga, display port etc... Might not be auto detecting.

Gpu slot cracked, etc...? Shipping damage?

Can try other stuff but continue refund/support with the seller.

I have checked the input yes it’s no signal regardless (on both monitor and LG C2). The GPU fan doesn’t spin at all on startup, not even for a few seconds.

RE not getting past 180W how bad is that for gaming? Is it worth getting the seller to replace/fix this? Or straight up pursue a refund? I mean…I am not prepared to buy this prebuilt (a good deal stretching budget to the absolute maximum) only to have to fork out more money for a whole new motherboard and then have to rebuild the entire thing anyway. That would be pointless. I don’t care about 200 FPS on games (if it’s the difference between 200 and 250 FPS or something lol). I’m more interested in AAA titles with decent graphics than competitive esports. But if it’s going to cause stuttering or reduce FPS significantly (like from 60-100 down to 30-60 or something) then that’s horrific.

unplug, take the battery out for a bit while hitting the power button as it's off. After that wait a couple minutes and then prepare it and start it back up. Might help. Not promising a solution.

Did you plug the monitor into the motherboard onboard video output instead of the actual GPU by mistake?

No. I made sure to double check that. Just as a test (and only to see if it would load bios) I tried the motherboard one but that was no signal too. Switched back to the GPU (tried all 3 displayports as well as the HDMI port) no signal on all.

Ugh. The CMOS battery? I don’t even know where that is on this board (unless it’s hidden underneath the CPU cooler…it’s a gigantic Peerless Assassin 120SE that covers even the RAM lol). Had to remove one of the cooler fans to even get to the RAM earlier…

Nope

Was it ever working? like before you changed ram? or it never booted up right?

No. Been no signal always.

Oh, well I will suggest again the cmos battery with the directions I posted earlier. If you're interested, just google it and should be able to figure out where it is on your board. If it's too much of a hassle, I understand.

If I have to remove the cpu cooler I won’t bother, in that scenario I’ll just wait for the company to respond on Monday (they don’t work at weekends) because it’s likely at this point I’m going to have to RMA it anyway.

Right now I’m deciding between asking them to fix/replace (as it’s their responsibility) or whether to request a refund instead. A bit worried about the motherboard from earlier comments with it apparently power limiting the 13700K. From what I’ve googled since (coz I’ve stopped trying to troubleshoot the no signal issue nothing is working) it appears it’s a thermal throttling issue due to low VRM? If that is true won’t the 6 case fans and the decent Thermalright Peerless Assassin 120 SE solve that issue? To clarify I’m not looking to overclock but I do want decent performance at standard clock (on eBay/manufacturers website it lists the cpu as “13700F” but the box supplied with the delivery shows “13700KF”, which is the unlocked one). I’m not going to be overclocking it but I don’t want to be severely limited at stock clock to an extent that it will negatively affect gaming performance. I will mostly use the machine for gaming (only other uses would be light web browsing. MS Office, etc) but mostly gaming so gaming performance is very very important. I know it’s a budget motherboard but will it be “good enough” for a i7 13700 (stock clock) and 4070 Super GPU with the intention of either running Ultra settings at 1080p (monitor) or 4K with DLSS (LG C2). If not I’m better off refunding (with that said though it was the only 4070 super build available within my budget). Even parts for my own similar specced build were more expensive, partly due to a promo discount.
