Hooray! After looking and asking numerous times I have accidentally discovered how to start a new thread. I found the button bottom right with the social networking rubbish. Anyway, down to my question. I have completed a new build and keep having the same problem. No signal to the display. I am not a gamer or video editor so I want to use the onboard graphics. So after trying about 40 different troubleshooting suggestions (and variations) I can still draw no conclusions. I have contacted ASUS and after doing several unsuccessful checks they suggested I return the m/b to the seller. I did this twice and I have now just tried the third replacement. I also tried Intel and after a time they suggested I return the processor to the seller. I now have the second processor in place. Still no joy. The monitor and its cable have been tried on a different desktop and they are in working order. I have also tried a second working monitor also with different cables and using both HDMI and DVI cables it won't work with the new setup. Power supply is over sized and brand new. Memory is from Crucial and stated to be compatible with my m/b and processor. This is my third build over the years and I've never had this problem before. Oh, and just to remind people, I have no signal to the monitor so I have no way of getting into the BIOS.
Does the mainboard have state indications by led or beeps? And please post the specs of the hardware.
Have you considered of trying a different monitor? Just in case your having issues with that monitor your using now?
Saw this problem already few times (and also happened to me), that display is set to pcie in the bios and does not switch automatically. Maybe you could borrow a graphic card or buy a cheap one to try out?
To be honest, that sounds like a real possibility. In my research I have found that on board graphics on some boards are disabled by default. I didn't follow this up because without a monitor I couldn't get into the BIOS to have a look around at the factory settings. I suppose I could throw some more money at this and try to find a graphics card. Compatibility wise, I haven't a clue. I will try to find out from ASUS what would be my most inexpensive option. I don't know anyone that builds or repairs their own PCs and as far as finding a shop around here that sells them I might as well be in Antarctica. Amazon and Ebay are my usual lifelines.
The most inexpensive option is a CMOS reset, old VGA cable would not harm to if the MB has a VGA interface.
You have a decent motherboard as far as age is concerned (DDR4 memory). I would first try to bench test the board by removing it from the case, setting it on a non-conductive material...wood or cardboard, leave only the cpu/heatsink/fan, one memory stick in slot 1 or slot A and connect the monitor to the on board video. Leave the mouse/monitor and keyboard connected with the power supply and see if this board will post. (Power On Self Test). If if does check the bios settings and then re-install the board back in the case, Do not add anything else and see if it will post when it is installed inside the case
I've seen that from my eyes, and not just one time. Having 2 or 3 deffective boards in a row has very small chance to happen... Another similar example is Z390 board I bought few months ago was unable to switch to "onboard" when my graphic card was plugged (was just interested to compare between i9 onboard graphic and my old AMD HD 6700), when graphic card slot is populated, bios warns that it couldn't draw enough power to enable onboard (and I have 850 W). It's just to say that some devices can be "hungry", or defective, adding another reason for the onboard graphics to be disabled and not switching. Yes, seems very stupid from a customer perspective. And so as usual, recommended way to pinpoint this kind of problem is to unplug everything (drives, pci cards, etc) then leave 1 stick of RAM and try different slots: Some motherboard prefer 1-3 ram slots populated, others 2-4 (but that should rarely prevent bios from appearing...) And then plug things one by one. But an external graphic card would be the first thing I would try in your case... I think one can buy a cheapo one for 30-40$... I'm not a pro in that field but I believe it would work with any card (my new z390 works with a 8+ years old graphic card) ps I don't have ASUS but I know many board manufacturer got rid of beep (Gigabyte for ex), don't really know why but anyway better to relate to board leds than some kind of beep "morse". CMOS reset would reset the bios to "onboard graphics disabled', if that's the case like I think.
My board only has HDMI, DVI-D, and RGB ports so trying a VGA cable is not possible. Until the problem of "no display" is solved I can't get into the BIOS to make any changes. I am still researching which discrete graphics card will be compatible with my board before I throw another expensive part at the board. I am waiting for an answer from ASUS tech support to find out if the default BIOS setting is what is stopping the integrated graphics from working. edit: Apparently the RGB port that is mentioned on the ASUS specification is just another name for the D-sub and VGA that we all know and love. I dug out a suitable cable and tried it. Nothing!
Honestly tech support are clueless (99 % of the time). If time starts to be an issue, I'd ready to take the bet tomorrow you got it fixed by buying cheapest ASUS graphic you find through amazon, instead of waiting (clueless) tech support reply. As stupid as it seems, it's the N1 reason for "no display" I think of now, since I had that problem myself and few time with friends configs. Even more when you say it is third board, second cpu... But I totally understand your hesitation. Because sometimes it can be CPU compatibility issue (like you need older gen CPU to be able to update bios for new gen CPU etc.), or sometimes motherboard cpu pins are damaged (nowadays they are almost like "hairs" : accidentally dropped a cpu one time, and its corner fall on boards pins, well...surgery tries only made it worst ) If you check the manual you'll prob able to see what the leds on your board are "saying" (if there are leds indicators on it)
I have the same Motherboard Asus Prime H270-PLUS it does have the VGA (Blue) port as i use it when testing on a old monitor -- (this board will become part of my new PC when i get time to move things over)... Back I/O Ports 1 x PS/2 keyboard (purple) 1 x PS/2 mouse (green) 1 x DVI-D 1 x D-Sub <--Blue VGA cable. 1 x HDMI 1 x LAN (RJ45) port(s) 4 x USB 3.1 Gen 1 (blue) Type-A 2 x USB 2.0 3 x Audio jack(s) My CPU i use is a Intel i5-6400 and the on-board HD Graphics work using that D-Sub connector as the on-board HDMI did not seem to function, but this could be down to the TV i used that had HDMI input as i got 'Not Supported' on the screen - probably the resolution was wrong for the TV. Any PCI-Ex Gfx card will give you a display the card i will be adding is a Nvidia 1050ti - have tested and that displays ok. One thing i do know these boards not like is a 2280 Western Digital NVMe type SSD it totally ignored it was there!
Still waiting for a response from ASUS tech. There are no LEDs on my board, apart from a couple at the ends of the PCIEx card sockets that seem to fade on and off. Probably just something to keep the children amused rather than having any real function. Interesting that you mention damaged pins. The second board arrived with just that. I should have been suspicious when I first noticed there was no plastic "protection" cover in place. When I went to place the CPU into position it was rocking. Rocking on a small cluster of bent pins. On further investigation I noticed that the little chrome back plate was not in a sealed packet and had fingerprints on it. In fact all 3 boards have had the backing plate come in an opened packet. I am becoming suspicious that Amazon is sending out customer "returns" selling them as NEW! Its just as well their return policy is fairly streamlined but it means my build is taking months now instead of a week or two.
Have you pulled the board out of the case and removed everything (See my previous post...including the NVMe drive) to see if will p.o.s.t. and get you into the bios? If one device is faulty it will prevent the board from p.o.s.t. So we need to know if it is just the board or something else, and this includes having it in the pc case too. You can use a small screwdriver to temp jump between pins labled "pwr" on the front panel pin out in order to start the boot up
I have seen instances where peeps have forgotten to install stand-offs on the mobo plate, or mis-located stand-offs too....
OK guys. I'll try to answer all your posts together. Yes, the extra (8 pin) connector is in place. I haven't tried with the board out of the case but I will try that later today. There are six standoffs in the case that correctly line up with the holes in the board. There was one extra in the case but I removed that one before fitting the first board to avoid any shorting issues. I'm tending to think Mr.X is right. This is the third board. It is pretty much at the end of its life as far as availability and I am guessing that Amazon are just sending out faulty "returns" to keep their stats up. There seem to be other sellers out there but the prices to me in France are anything up to double. Answer from ASUS tech this morning says the only way the BIOS defaults to disabled is if you fit a discreet graphics card. I don't have one so the only way that could have happened is if the board is second hand and someone else did it previously. Food for thought.
