Computer turns on but no video on my Monitor.

June 2, 2013 at 09:37:40
Specs: Windows 7, Intel(R) i3 3.30GHz / 8 Gigs
I have a new computer that was working fine a few weeks ago, then one day I had a Graphics card called XFX HD 7750 on and it worked, for a while, then it just didn't work, i thought it was the card because the PCI-E slot it was using did work. I exchanged it for my moms, and the card did work on my moms computer, she had an Nvidia GTX 550 and I knew now both of those worked. It still shows no video, and everything is plugged in. I hear sounds of booting up into windows and all of my programs starting up, I hear all windows sounds but no video, I'm using a DVI cord that I know works because my mobo has onboard video and it works I'm using that right now my specs: 8 gigs of RAM Kingston/550 W PSU/Nvidia GTX 550TI/Asus motherboard/500 GB hard drive/Intel Core I3-3220 CPU - My overall question, How do I get my Nvidia card to work, I know it works, I have tested it on another computer, Fans spin and I hear sound. Just my monitor goes to sleep and it doesn't come back. Could it be the Motherboard? If anything -- The computer I don't think knows that it has an Nvidia card on it because it doesn't show in Device Manager, the only thing that shows is Intel(R) HD Graphics. I really appreciate it, Thanks.

It's odd that it was working then suddenly stopped.

Clean the card edge connectors with a pencil eraser and see if that helps. Also pop it in and out a few times to clear any oxide off the socket.

Always pop back and let us know the outcome - thanks

Since you're getting the normal windows sounds the motherboard and hard drive must be OK. The on-board video works too so it pretty much has to be the card.

When using the on-board but with the card installed also, are there any conflicts showing in device manager?

Do you have to do anything special in the bios to enable an add-on video card or disable the on-board?

Maybe it's a resolution problem. Just after turning it on start tapping F8. If the boot menu comes up, choose safe mode and see if that works.

But the card works, it's been tested in another computer. It works perfectly fine, the On-board video works very well, but the game I could run best is Grand Theft Auto San Andreas.. the rest works very slowly. The GTX 550 is supposed to be Plug and Play.. the drivers wont let me install because it sais it doesn't recognize a Hardware compatible with those drivers and there are some conflicts but it's for USB controller that doesnt have any drivers. But I don't think thats it.

Everything is plug and play now but that doesn't mean you don't sometimes have to provide drivers. Maybe you have the wrong ones? You mention 2 video cards--the original HD 7750 and the GTX 550 from your mother's computer. Here's the drivers for both:

Windows 7 64 bit drivers for HD 7750:

http://support.amd.com/us/gpudownlo...

Windows 7 32 bit drivers for HD 7750:

http://support.amd.com/us/gpudownlo...

Windows 7 32 bit drivers for GTX 550:

http://www.nvidia.com/object/win8-w...

Windows 7 64 bit drivers for GTX 550:

http://www.nvidia.com/object/win8-w...

The card failed while it was working but works in another computer. Maybe it's just not providing the resolution it's set for in the first computer but is providing a different resolution in the second computer. That's why you should try it in safe mode.

If there's a possible conflict with a USB device then remove it temporarily and see what that does.

I used to have the 7750 on my computer but something happened I thought it was broken. so I put the 7750 in my moms computer. and it worked. I put the gtx 550 on my computer. that card was in my moms. and it worked good. I put it in mine and it didn't work. again. how do I get to safe mode if I can't see anything on the screen?

Sometimes a computer posts so fast and gets to the windows loading phase before the monitor warms up enough to show an image. Of course that's not as much a problem with LCD monitors but then PCs are faster too. Anyway, in order to get to safe mode that would have to be the case with yours. (I can only speculate because I'm not sitting in front of your system.) So if you turn it on and then immediately start tapping F8 maybe the boot menu eventually shows up.

If not (and I'll admit getting to safe mode seems unlikely) then it must be the slot since no video card is working in it. Either it's bad or is it possible it needs to be configured/enabled in cmos/bios setup?

Did you do exactly what I suggested in #1, especially as the card works in one computer but not another? Alignment differences can cause problems due to slight tarnish which is rarely visible.

I have now another problem. I fixed it. Kind of. I installed a Program called SIW which checks my whole computer out and I found very peculiar things that lead me to believe that My card IS in fact being read by the computer I have two display drivers but only the mobo one shows up on my Device manager as Standard VGA Graphics Adapter. I re installed Windows and I quickly went into Device Manager and two Standard VGA things appeared one PCI Bus 1.0.0 and and PCI bus 0.2.0 then the one on PCI bus 1.0.0 quickly disappeared. Anyways the program SIW informed me of two Display adapters that I have..

SIW shows the on-board as enabled and the added video card as disabled. When adding a video card usually the card will disable the on-board or you disable the on-board in cmos/bios setup or you specify there which adapter has priority. If you're not sure how that works with your bios you need to check the manual. I didin't see that you identified the model number of the board except that is was an Asus.

Also, according to SIW, both adapters are identified as 'standard vga graphics adapter'. That usually means you haven't installed the drivers, which may be expected if you just did a fresh OS install. You might try installing the nvidia drivers but I don't think that will make any difference as far as its card being seen but I'd hate for that to be the solution and not mention it.

if I attempt to install the Nvidia drivers it sais it can't find a hardware compatible. I can install the normal MOBO drivers but that won't do anything useful but all I know is that the card is in fact being read I just dont know how to enable it.

the MOBO I think is a p8b75-m/CSM

Connect your monitor to the onboard video.
Boot up and repeatedly tap DEL or F1 or whatever other key you need in order to enter SETUP. If the bootsequence is hidden behind a manufacturers logo splashscreen then you need to hit ESC key to see what's going on.

Once there you can scroll through the menus until you locate the graphics/video settings and usually there will be an option to default to PCIe if present. Change the setting, save and exit. Shut down. Shift monitor cable to the plug-in graphics and boot up.

Here's the download page for that series motherboard:

http://support.asus.com/Download.as...

You can download the manual there. In section 2.5.5 in the bios setup section it describes the 'graphics configuration'. Under 'primary display/auto':

"allows you to decide which graphics controller to use as the primary boot device. Configuration options:Auto/iGPU/PCIe/PCI"

So check that out in your bios setup and hopefully changing the configuration there will solve the problem.

Try AUTO and PCIe. Be sure to save the settings. Are there any options in setup to configure the PCIe slot itself?

If all else fails you might try a bios upgrade just in case it's some fluke with the bios. But that's a last resort.

If there's nothing else in the bios that might be affecting it we may be back to it being a problem with the slot. Can you see in the slot? Maybe there's a bent connecting pin. Derek mentioned making sure the card contacts were clean. I figured they must be since it worked in the other computer but check again. Is the card firmly installed in the slot?

I was thinking it's connected good enough to be ID'd by SIW but not to work.

I can't remember if this was discussed above but if you connect a monitor to the nvidia and start the computer does any posting/pre-windows stuff show on its screen like it does with the on-board adapter? If not it's got to be a hardware or bios issue and not drivers or anything OS related.

Make sure bios graphics is set to AUTO or PCIe when you check.

Yeah, that must be because the bios isn't enabling it. Windows knows it's there (at least for a few seconds) but can't do anything with it. Under the 'view' option in device manager you can click on 'show hidden devices' and it might show up again. But there won't be anything you can do with it until the bios enables it.

I can't think of anything else but the slot, bios or some other problem with the motherboard.

I thought you'd already verified that both cards worked in the other computer but neither worked in yours. If that's not correct and you retry the original card and it works. . . well I don't know. The slot would have to be good in that case so I'd guess there would have to be some incompatibility between the nvidia card and the motherboard or bios.

If you do retry the original card make sure you set the graphics option in bios setup as AUTO or PCIe.

This link is just to show that a cap file is sometimes used for BIOS Update:

However, if you are intending to go ahead (and assuming you got it from the motherboard manufacturer) then I would seek precise installation advice from them.
If you don't get it exactly right then you mobo is definitely a brick.

With BIOS updates there is usually a list that tells you what issues it covers.

Just to add that BIOS updates (unlike other updates) are not something you do on a regular basis. They are usually only needed in very specific circumstances, such as to allow you to use a different CPU.
