New build - some boots have no display?

Amraam · 9 Jan 2018 at 20:19

PC is built, except for GPU which is still in this system. I've booted up new PC, gone into BIOS to set XMP etc but I've noticed that about one in three boots results in no display. I see A9 "normal setup" code but nothing on monitor.

Monitor is X34A; could it be something to do with Gsync?

Dp between motherboard GPU and display, yes. 980ti isn't connected, as that's in the old system still. Same dp cable though.

It's really annoying. I'll be in the middle of setting up the bios and boom, no signal. No codes or light changes on the mobo that I can spot.

Sorry, Plec, I'm tired and didn't see the bit about the lead. Nope, haven't got one to hand, but will take the PC to work tomorrow and try there.

Asus Maximus X Hero Z370 (latest 1003 BIOS)
8700K
2x8GB GSkill C17 3600
Seasonic Focus+ 750W Gold

No worries bud, understandable that your tired/frustrated with a new build not playing ball.

It's a quality build with a Tier 1 PSU backing it up.

I would perhaps clear the CMOS and try dropping the memory to 3200 as a precautionary test too.

Thanks I'll try resetting the BIOS, although it appears that update process did that anyway. The RAM defaulted to 2133 and it did it then. It was the second POST before I got display, then simply going to set the system time was enough to kick it off again. It seems random; it will either post fine, post without display, or post with display then go off when randomly. Really hope it's not a faulty item...

Really poor video, bit when it does appear on the display, it flickers like this at first:

Video doesn't show it, but it's like 3/4 of a frame of static.

I'm guessing you have - but have you installed the latest INTEL VGA driver and chipset drivers etc?..

I've not even installed Windows yet; this is purely in the uefi bios.

Sorry, phone spam , tried one stick of ram ?

I'll add that to the list of things to check, although both report correctly in bios.

I need to move fast because I ordered all the gear on 30th Dec but only started putting it together tonight due to amazon taking forever to deliver the ram.

Raise RMA with OCUK anyways, can always point them to the thread. They'll test the board . Unfortunately your out of luck having your hardware tested - not sure there RMA includes using same exact setup ?

I didn't buy from OCUK this time, I bought it from the place that has the name like what you do to a bar code... Ha. They had a sale on all the bits I wanted so was a no brainer.

Sorry, edited after you posted, can also be fault with CPU, buggie onboard GPU, can happen, though most I see are faulty ram controllers
Not sure their RMA... Though I do know Asus "invest" heavily in them

Well of it turns out to be a glitch integrated GPU I could live with it as my 980ti will be going in anyway. Ram would be the preferred fault as that's a 2 min fix.

I'll be in touch tomorrow, thanks for the help, guys.

This morning, I have it connected to a different display via HDMI and so far, no issue. Have powered it up and down into the BIOS several times and no issues. It also seems to POST faster and without the flicker of white noise. Trouble is, I don't know if perhaps the RAM wasn't seated right etc, or if it was DP all along, or something else. I'll try DP now and see how it gets on.

Update1: DP with this lead/screen works fine. Seems to be either a config issue between the x34a and this board, or the fact I was using a 4 gang extension. I'll try without tonight.

Looks like you're zeroing in on your problem.

The extension could be factor - it's amazing how many innocuous problems have turned out to be due to poor quality or failing extension cables. But you have a few other things to definitively rule out first.

Best of luck - hope it turns out to be an easy fix.

Thanks. Windows is installed now, and I haven't had a single issue. I'm confident enough to say that there's probably not a fault with the new system, as it has been flawless so far. Thankfully I only had it plugged into that particular extension as it was conviniently placed near the work bench. I'll not be using that when it's fully up and running.

Had it on and off all day for software updates, installations, and other tweaks and not once have I had an issue. Let's see what happens tonight. I'll make sure to connect to the surge protected box that I normally use. I'll temp install my GPU also to ensure that that works fine. Once I'm happy, I need to research on 8700k OCing. I've noticed even on standard BIOS settings it will jump to 4.something Ghz.

Home, plugged directly into the mains, using hdmi, and no issues...

1 final step though.....

take previous extension cable and fling in the bin!

Agreed.

Thanks for the all the help guys, appreciated!

All up and running and OC'd to 4.8Ghz. Pretty disappointed to see that I've gained pretty much zero performance in Skyrim SE or Mass Effect Andromeda, but I reckon it's probably more my GPU due to gaming at 3440x1440. Roll on the new nvidia release...

I do have a LOT of mods in skyrim too, and ME:A I only did a quick test. I'll try again about the Tempest in the cockpit as FPS would often drop to ~20 there!
