Hello, i just put together my first pc but i can't get a display signal from my graphicscard.

I have a geforce GTX 660 graphics card and my mobo is msi 970A-G46. I'm using a 600W PSU.

I've searched forums and the thing to do in this case seems to update my BIOS so when my mobo doesn't have integrated graphics I tried installing 2 other cards but still no signal. Therefore i cant update my BIOS.

The other cards i took from other computers and they were Radeon HD 4850 and another Radeon HD card i dont know the model of.

So what I thing is that, either somethings wrong with my brand new mobo or i have missed something when building. Since this is my first computer i put together that's not unlikley but everything else seems to power up like it should. Even the fan on the graphicscards work. But no display signal.

I'm getting really frustrated and would appreciate if any one could help me.

Thanks and please excuse my choppy english :)

If this happen with just one card, can be a faulty one, but with 3...

Sometimes it is the most obvious what we are missing.

The monitor is also new? Check that it is turned on, and both the current and video cables are firmly fitted on the back of the monitor.
If you got a laptop or another computer so you can test the monitor will be usefull too.

Back to the computer, in some motherboards, the system will turn on and turn on also all the lights, fans, etc, but not boot un to the POST screen.

Remove the CPU, check that there are not bend pins, reinstall it, and ensure it is porperly locked. If it is not well locked, the system will not POST.

How many RAM modules you got? Try to install only 1, in the #0 slot (check on your MOBO's manual).

The GTX660, got the PCI-E 6 pins current cable connected? And the cable is connected to the PSU (if a modular one)?

Last idea, the GTX660 card should be installed on the PCI-E slot closer to the CPU. If you are doing it this way, and not any of the other tests work, try to install the card on the other PCI-E slot (looks like your mother board got 2...)

I know that it can be very frustrating when you build your first rig and thing goes wrong, but don't desperate and don't give up :) 

Hope it helps.

Firstly, before you even insert the card, go into your BIOS and then find the settings for integrated graphics. Then choose the option that says x16 lane. Many times the setting is selected to auto and it runs from the integrated chip on your cpu and it doesn't detect your gpu.

Secondly, after the BIOS settings are selected to the PCI Express slot, shut down your computer, insert the graphics card, plug in the power connectors from your PSU to your graphics card (2 6-pin power connectors i guess), then start your computer. It should work just fine.

The best solution is:
1. try resetting your bios by removing the cmos battery
yeah this is a shitty problem as i have experienced it with my 8400gs and gt520

Hi there, i suffered a similar problem. Can you state the brand and model of your PSU? I couldn't get a GTX 560 working because i had a cheap psu even though it stated it was 750w. I bourght a corsair GS700 and am awaiting a new video card but with this psu it powers my current work and everything works perfectly. Just so you know try using your computer without the card in and use the mobos onboard vga, least that way you can determine any other issues and get a signal to attempt a fix.

Remove the RAM and put it back. It worked for Me. Had similar problem with My HD6670.

This might be because of your monitor because older monitors may have correct ports but do not work with newer GFX cards, i had this problem when i tried to do a dual display with a GTX 660 (Gigabyte) and i used a VGA connector into the back of the graphics card through a DVI-D adapter because GTX660's do not have a VGA port, and i got no signal as well, tried a lot of things to get it to work, even downloaded software which was supposed to recognize monitors connected, but some are not compatible with newer Graphics cards.

I hope this helped.

The monitor is new or old?vga or hdmi?any warning on the screen?
I never had simiral problem.Also boot in windows?
Please specify in order to help you.

Don't worry. I had the exact same problem when I installed my gtx 660 ti. Luckily I had integrated graphics so I was able to go online and find the answer. What you need to do is disable your "secure boot" option from your BIOS. It should be enabled by default so find it and disable it. Since BIOS's vary from brand to brand you may need to go online and look up how to disable the secure boot for your particular BIOS. Just search something like "msi 970A-G46 disable secure boot". Once I finally figured out how and disabled mine my display fired right up and my PC was good to go! Try that and let me know if it works. Good luck!

If you could tell us a bit more it may help. But check these things.
1. Make sure the graphics card is FULLY secured in the PCI slot
2. Ensure your graphics card is powered fully, and your PSU meets the requirements.
3. Make sure you installed ALL of the risers for the motherboard. This is a big one. Your computer and fans may turn on, but nothing will work. If this is the case, you've fried your first computer.
4.Attempt using different inputs on each card, such as VGA and HDMI. Some cards will only work with VGA properly until you install the drivers.
5. Ensure that your monitor is on the right input (I.E, looking for VGA while you use HDMI)

I had a problem like this not too long ago, I bought a brand new monitor plugged it in and it worked great. I then updated Windows to sync my graphics card and monitor. After restarting my monitor had no signal whatsoever, the GPU fan and everything in my computer works but it would not display. I tried everything listed in this thread; removing the CMOS battery, reseating my RAM, etc. but it didn't work. I then realized that I accidentally plugged my monitor into my motherboard's onboard graphics instead of my GPU's sockets by accident and didn't even give it a second thought until after unplugging and plugging back in my monitor. It may sound dumb(and I feel dumb for doing it) but don't write off user error and check where it is plugged in XD!

Have you plugged in the motherboard ATX power? It is a 4 or 8 pin connector that usually plugs in near the CPU. When I built my first PC, I forgot this and had the exact symptoms you are describing.
Also, have you plugged in the GPU power cables? Graphics cards require more power than they can take from the motherboard, so you must plug in extra power to them. Look around on the card for what looks like a power plug, they can be anywhere from 4 pins to 2 8-pin plugs. If you find it and it is not plugged in, you should have something that fits on your power supply. Try it and report back.

try a differnt PCI-E port ?
September 29, 2013 5:30:21 AM

Try doing what Ballantin Sais. He is the first to reply. In General when you are having problems like that on your computer, then you need to run a skeleton run. What this means is, You install as few hardware as it is possible. Remove any peripheral fans you have installed on your tower from the power lines. At some point i had the same problem on my end. I didnt have enough juice to feed all the system and had to remove 2 fans! Now i got a bigger PSU and all is good!

You check an RE-CHECK that every wire is properly inserted its slot, every card, is properly locked in place (push firmly but gently until you hear a click sound) and make sure you are providing with power to your GFX card. If you dont allready know, most gaming cards (ex. GTX #40-50-60-70-80-90) require additional power from 1 or 2 6pin PCI power supply cable. Yours needs 2x 6pin PCI. If u dont have a modular PSU, and u have used the same cable to power other units as well as your GFX card, then trying using a PSU cable only for your GFX,
And in any case your Mother board is beeping or flashes red lights, then open the manual and read what that means.

If all the above fails, then take it to a shop. You might have done something wrong, or a component might be damaged. As this is your first time going into this sort of work you should allow a professional to assist. But make sure to ask what the problem was and then tell us about it. Some shops tend to exaggerate to get more out of you.

Hope you get it to work soon!

go into our bios and disable security boot and enable legacy boot.

Try re-seating your ram. That fixed my issue.

Happened with me the same, Tried all the things and I solved the problem myself. but I don't think that the user "Absolute" is active on this thread so I find no use answering :(

what is Your Cpu The Exact Same thing Happend to me And It turned out my fx8320 was not compatible with my Mobo
For example Check the wattage of your cpu is Lower than what the msi mobo can handle

Hope this helps

Excuse me, here the user is trying to use Multi-GPU's with Different GPU Companies! It's IMPOSSIBLE to use multi GPU with an AMD/ATI and NVIDIA Card. Now what you've got to do is get another GTX 660 and pair it via SLI. You can also use any downgraded GPU supporting SLI but it'll start frameskipping and the slower card will also slow down the faster card. You must know everything detailed and correct before trying to build a PC. Anything can happen.

I had a similar problem on a few of my rigs over the years too. Removing, cleaning the contacts, and re seating the RAM has helped in a few instances. Use rubbing alcohol and a clean lint free cloth for this. Always check power connections as others have stated above. Also ensure that if your GPU has 2 DVI ports on it, plug the monitor into the one closest to the motherboard when the GPU is set into position. Another issue I have had before is the cables (VGA, DVI) that are supplied with the monitor when you buy it. They are usually cheap, and will sometimes cause issues like this and/or corrupted display. If possible, try a new, quality cable. And, preferably DVI not VGA with a DVI adapter. More likely than any of these things causing the issue, is that the PSU is not operating properly. I have had this problem before as well with cheaper PSU's. Says 680 Watts, but can't power on a 400 Watt system. PSU's seem to be the cause of many funky PC problems:(

Steps you can do are following:
1. Remove GPU and inserted it properly again.
2. Take out your RAM and clean them with dry clothes only edges and then insert them carefully.
3. Clear your bios by removing small cell present on your motherboard or by using clear bios circuit on motherboard
4. You can also try removing your processor and clean it and again fix it properly.
5. Check your hard disk whether its working properly or not.
6. If above 5 steps does not solve your problem then you should buy new monitor.

Buying a new monitor doesn't really do anything. I spent £80 on one and the problem persisted. From what I can see, the monitor's got absolutely nothing to do with it.

Have you ever thought that your motherboard might be dead?
March 28, 2014 5:47:49 PM

my guess is the RAM. And removing the graphics card and use intergrated graphics of your CPU if there is signal then your GPU is the problem
May 9, 2014 7:49:37 AM

this might be also caused by bloated capacitors on your motherboard and you can replace them.I dont know wether it will work or not but its worth a try.
May 17, 2014 12:22:19 PM

its a option in bios. you have to disable fast boot this will search for new hardware.
August 7, 2014 9:19:10 AM

Are you using HDMI or DVI. When I built my PC I had to use a old monitor because i couldn't get output over HDMI but once i installed my drivers I could get an output try using DVI or VGA.
