Need help urgently, stuck in VGA, Cant detect graphics card

[Sameria]

Hi,

about 3 days ago my PC randomly rebooted (I wasn't doing anything out of the ordinary on it). How ever when it rebooted it was stuck in 800x600 mode (VGA settings) and I couldn't change this. When I tried to find it in DXDIAG it did not show my GTX 580 at all. Also it showed weird signs in the post-bios screen when booting.

I have already looked at my monitor OSD settings, these are good. I replugged everything, tried different PCIE slots for my card but none of this seemed to work.

I did a virus scan resulting into finding absolutely nothing, and to be honest I'm at my wit's end.

I have reinstalled Windows figuring this might solve the problem, but sadly enough it didn't.
I have reinstalled all the drivers hoping this might work, but this didn't work either.

I haven't installed any different programs prior to the systemfailure, and after the steps I've taken to try and solve this I'm starting to think my GTX580 commited a technical suicide. However before I go ahead and buy a new graphicscard, I want to be absolutely sure I've tried everything possible.

I'm not the most tech-savvy guy so any help at all would be appreciated.

I do not have a spair system to run parts on individually so I can't properly test my gear, sadly enough.

I hope someone can help me out here!

My current set up :
nVidia GeForce GTX 580
Coolermaster G750M
Asus Maximus IV Extreme-Z
16GB RAM
intelcore i7
Windows 7 Ultimate

If you need any more info please let me know, I'll try to find it as fast as possible.

Here's a link that should show the post-bios boot screen.

I hope you guys can help me out,

Kind regards,

Dave

Step one: Clear CMOS. I would also recommend flashing your BIOS after downloading most recent version (you can find it for your motherboard on ASUS website).

Can you see the GPU in BIOS? If not, move GPU to a different PCIe slot and try again.

I'll try this, I'll get back to you in little bit. Thanks in advance for responding!

This does help me further, I'm going to flash BIOS in a sec, CMOS reset did give me some vision but it tells me to boot from BIOS. Any tips on how to do this the savest way?

From within the BIOS, find the boot section and find what devices are available to boot from. Hopefully, your original system disk is still showing as available.

I've tried what you said, it gives the standard option it has been giving for the past days I've been trying to fix this.

uploading pics to show what i see on boot after CMOS reset etc.

This is what I see when I actually boot and reset CMOS

what my bios detects @ GPU

Boot option

hope this is helpful and offers any options I can go forward with. Booting from BIOS after reset didnt fix it.
Still in VGA mode aswell.

Not sure what the AOSO boot device is? Is that a USB disk you're using to override? Does your SATA screen show your hard drive and is it selectable as a boot device?

Completely unsure on what the AOSO boot system is, its always been that way. And this is the only option it provides.
