Resolution stuck at 800x600, Cant find graphics card in dxdiag

[Sameria]

Hi,

Recently I was playing a videogame on my pc and it crashed all of a sudden, This resulted into my resolution getting stuck at 800x600.

Now I figured it were my drivers or a virus but after updating and scanning, the problem is still here. I proceeded with reinstalling windows, figuring that might help (I'm not too techy so just aiming at the basics). This didn't help a bit either.

I did however notice that when I boot my pc, after the Bios screen it shows weird signs.

Also when using DXDIAG, it can't seem to find my Graphics Card. I did check if it's plugged in correctly, and it is, I haven't changed a thing for a month or so and it has been running smoothly all of that time.

Sadly enough I don't have any spareparts to test individually on.

I'm using a nVidia GTX 580.

I'm running windows 7

Does anyone have a clue what's going on and how to fix it?

ill start off simple, "I did however notice that when I boot my pc, after the Bios screen it shows weird signs.", what weird signs? mind uploading the picture maybe if you can
dxdiag cant find gpu,is the same thing going in device manager ?, if you're still not sure try to install software like gpu-z, it should detect the card, or go very deep and use the bios to check whats in the pci-e slot, if the bios has a board explorer kinda thing that will let you know.

sometimes windows can install the gpu drivers right from device manager, try to click update drivers from device managers at display adapters and let windows do it automatically
or go to nvidia site use the driver designed for the gtx580

worst case scenario is the gpu died, but as long as its still displaying it shouldn't be dead
you can try to buy a second hand old gpu to test, if you want to
but try the suggestion i've left, maybe one of them may help,

Hi, thanks for responding! The images I'm seeing are as following

Now I've come to believe this suggests it's a motherboard problem, I've tried to reset CMOS but this hasn't helped either.
I can't seem to find the proper drivers to download and install and when I do find a program that can help me out here I keep having to upgrade the program to make it useful -_-

Any suggestions or links to where I can find proper drivers for both motherboard and my GTX?

I've been searching like mad.

I'll give the GPU-Z a try right now. Thanks again for responding in the first place!

Some extra info :
I'm using the Maximus IV Extreme-Z motherboard.

After CMOS reset I did get into the screen where it tells me to boot from BIOS but I can only select the usual program and that keeps giving me the same results. DXDiag wont detect my Graphics card still.

Thanks again !

gpu-z does find my Graphics card

tried this gpu driver? http://www.geforce.com/drivers/results/113442
besides if your mobo is working fine before that crash surely it doesnt need to be updated just yet

I have tried to update it from the auto-updated on nVidia's program, however it cant make a connection to Nvidia for some reason. And whenever I do update the driver, the screen starts to blur with blue and green shades and its barely useable.

after the driver's done installing it goes to blur? now im getting suspicious that the card is bust, try to use older drivers and use msi afterburner to lower the clocks if possible, maybe the card is dying slowly

btw your motherboard's intel right ? why dont you try to run the pc with the built in igpu ? if it does fix the issue your gpu is most likely bust
