New MOBO and CPU: Graphics failure.

Th3-Trinity · Feb 5, 2015

I just recently purchased a new ASUS motherboard, Intel (i7 4790K) Processor, and a Graphics Card (Nvidia GTX 980 Matrix-P by ASUS). I replaced the motherboard AND the processor and tried to connect directly to the motherboard through on-board graphics. I do believe everything is installed correctly because all of the fans are running at a decent rate and the HDD IS posting. It sounds like it is booting, but I have no picture. The RAM (Not new Ram. Non-ECC DDR3) is set correctly. It sounds like everything is in line. I attempted to reconnect through my old GPU (Nvidia GTX 780 by ASUS), and it came to life and started up, but there was no signal to the monitor, same as intergrated Graphics. Is there something I should have done before transplanting the board? Note I do have enough power and all slots ARE compatible. I do not have the specific MOBO name at the moment, but can supply it later if needed. Thanks for ALL of the help. This is not my first time using this forum for troubleshooting purposes, but it is my first time posting my own question. I hope that this will be a good experience and that I can in turn offer my experience to other users in need of help.

Generally, when a 3rd party graphics card is installed into a slot on the motherboard, the BIOS auto-disables the integrated graphics, so connecting a monitor to the latter comes up blank. Some motherboards support using both 3rd party and integrated graphics at the same time for multi-monitor usage, but in such case, you would have to manually enable the iGPU in BIOS.

I tried just integrated first, then the original card. Neither worked. I am not even getting a bios screen. I just need to know where the problem is so I can troubleshoot. I replaced too much right off so I need help figuring out what my symptoms are caused by. The CPU doesn't sound like it would cause an issue would it? The board is powered correctly then. Idk what is wrong. Is it a driver issue?

ThomasLeong · Feb 5, 2015

It won't be a driver issue as you said you are not even getting a BIOS screen. It would be a driver issue after booting into the OS since it (the OS) currently contains drivers for the old mobo and its on-board devices; so then, it would be a matter of uninstalling all those, and installing the ones for your current mobo.

Could be -
1. BIOS not yet updated for the i7 4790K - check your ASUS manual, there may be a way to update BIOS on power on.
2. Plain old connection problems between source and monitor - how are you connected: VGA, HDMI, DVI, Display Port from source (graphics card or integrated) to Monitor (VGA, HDMI, DVI, Display Port). Digital connections may not be converting to analog except with the correct adapter, usually active adapter. Digital to digital should normally be fine. If your DVI is a DVI-D and not a DVI-I, then monitor needs to be DVI, HDMI or DP, and not VGA which is analog.
3. Bent pins on the i7 4790K when you installed it. The pins are copper and easily bent. No choice but to remove, check, and if any, carefully straighten the pins with a tiny screw driver and credit card inserted in between the rows/columns of pins. You-tube has example videos of how to.

I did not use any force when inserting the i7

I am using HDMI to a 1080p monitor, so I don't know there. The board should just work when put in? And would it even post if the CPU was faulty?

ThomasLeong · Feb 5, 2015

Doesn't need force to bend those pins. Just an accident will do it - either the ones on the cpu or the ones on the motherboard. It's a 'last resort' check since it involves taking out the cpu.

Have you updated/flashed the motherboard's BIOS to the latest? The i7 4790K may have been released after the manufacture of your board, and its present BIOS cannot detect it, therefore, no response.

Not sure if this applies to you as you did not provide info on your OS, etc -

Additionally, you said you replaced mobo and processor. What about the hdd? Did you just re-use the previous hdd with the OS installed for the old mobo and processor? If so, there will be drivers and settings in that hdd pertaining to your old mobo and processor. It is a shot in the dark, but may affect your new 'build'.

Th3-Trinity · Feb 6, 2015

Thanks for all of the responses guys.

I DID just use my old hard drive will all drivers for the old MOBO in tact. I am using Windows 8.1. How does one update the bios?

The MOBO is asus q87m-e by the way.

Th3-Trinity · Feb 6, 2015

Should I attempt to re-build my own RIG and uninstall old drivers and reinstall the new? Or just install the new?

ThomasLeong · Feb 6, 2015

I'm not familiar with that mobo. However, it seems to have what it calls "ASUS EZ Flash 2". Check your manual to see if there are instructions on how to use the feature.

Else, these may also help -

Good luck!

Rather than messing with the old hdd, I'd recommend -
1. Decide to install Windows 8.1 into a new hdd or SSD (recommended; 128GB or 256GB SSD will suffice for most users). Do not plug in the old hdd until after the new install works. Then you can copy/transfer old data/documents to the new hdd/SSD.

2. Be aware of the NVidia article pointed out earlier -
http://nvidia.custhelp.com/app/answers/detail/a_id/3156/~/when-installing-an-after-market-graphics-card-into-a-certified-windows-8-pc

3. Update your BIOS to support 4th Gen Intel processors (your i7 4790K)

4. Install Windows 8.1 without the 3rd party graphics card

5. Test install with basic operations

6. Install your 3rd party graphics card and driver

7. Test

8. Hopefully, all should be well after this.

Good luck!

Thanks a ton friend

Will give it a shot and let you know if it works

Alright then, the BIOS seem like they need to be updated. My i7 AND i5 do not work, but it does sound like the HDD is still posting. The front panel is installed correctly because of the lighting function. When I add power to the PSU (Plug it in) the fans all buzz to life and the HDD Posts, but runs only for about 45 seconds before dying down again. After this. the power button works. Although the switch is now functional the rig will die down again in a few seconds.

Due to the i5 not working either (Both are 4th Gen) and me finding an update to work with the new 4th gen CPUs on the ASUS site, I believe that the bios are not yet capable of utilizing the new CPU. I do not, however, know how to use the USB flah tool as the board does not appear to (at first glance) to have a flash button.

Even if it does prove to be that my board cannot use the i7, why would the power button not be working correctly and why does it turn off after "booting".

ThomasLeong · Feb 7, 2015

ASUS has a DOS-utility to allow updating the BIOS. There was a picture of it at one of the web-sites/articles I pointed out earlier.

On the other hand...mm...seems like more trouble than it's worth (time wasted trouble-shooting). Are you able to rma the board, or take the whole pc to your local supplier to trouble-shoot for you or at least change the motherboard for another model? Because a local supplier has option stocks in hand, swapping parts to trouble-shoot is easier to nail down the problem.

Gotta run...(I have a full day working outdoors in the sun and rain today).

Th3-Trinity · Feb 8, 2015

Yes, but my issue is that I can't actually get a visual. I can't see the screen to get to the bios v.v I believe I need a BIOS flash to support my 4th generation CORE CPUs, but I cannot obtain an image to do that much.

ThomasLeong · Feb 8, 2015

Sorry, misunderstood you then.

Try this -
1. Remove 3rd party graphics card from pc slot.
2. Leave power off, and clear CMOS (could be just a button switch on mobo, or needs a jumper to another position - check your manual)
3. Connect monitor to motherboard integrated graphics display output
4. Check other connections - RAM firmly in place, SATA cables firmly in, etc.
5. Power On - is there a Post visual on screen? If yes, hit Delete key to get into BIOS.
6. If no visual on screen, suggest you send motherboard in for RMA or someone else to test the monitor, connections, etc to confirm that motherboard is at fault.

I called my father up (Professional Project Manager for General Motors) and he did an over-view of my system. He concluded that there were bent pins on the motherboard 1150 socket. I didn't even realize how small these pins were! I know also for a fact that I did not bend them myself. I worked with two others and managed fine. There were a total of 8 random bent pins on the CPU socket. Even after attempting to re-bend pins, there was no help so it may have had other issues. Anyhow, I went and got a cheap MSI MOBO and I am typing this up on my running rig right now

thanks for all of your help!

ThomasLeong · Feb 11, 2015

Sorry to hear re-bending the pins on the mobo did not help. That's unusual. You first said the motherboard was new - any chance of a RMA?

BTW, the pins are easily bent. Usually accidental, and the common way is when the plastic cap to cover the cpu area is being put back into place. One slip and that's it: bent pins. Been there, done it!

Been happy to help, and happy computing!

Th3-Trinity · Feb 21, 2015

Thanks again man

And no, it was kind of weird because the pins were all spread out. 2 here, 3 or 4 there. No way I did it or else they would have been more localized. I saw something online about bent-pin boards going out from Asus and Newegg not refunding them.
