Computer does not recognize graphics card after hard shutdown.

My computer went into sleep but this time would not come out. The computer would not come out of sleep via the keyboard or mouse movement. I had to power the computer off by unplugging it to get it powered back up. When I powered back up my monitor screen now has huge icons obviously something is wrong with my graphics.

Everything else seems to be fine. I went to device manager and looked at my display adapter and my computer has disabled my graphics card driver: NVIDEA GeForce 8500 GT which explains why my screen resolution is now: 640 X 480 (4 bit 1 HZ). Yeah it’s unsightly.

This device in the device manager is yellow and disabled. The error I get is Windows stopped device because of problems (code 43).

I have tried to roll back the driver, find a driver update (which is says it’s up to date), system restore to previous dates (the issue still remains) Nothing seems to work. I cannot seem to enable this driver. When I uninstall the driver the computer re-installs automatically but the problem still persists.

When I go check: Control Panel> Personalization> Display Settings all I see is:
Monitor Tab: Default Monitor is on, Colors: Lowest (4 bit), Resolution: 640 by 480 pixels. On the advanced tab for the Adapter Type and Information all fields say (unavailable). My graphics card (physical) is not listed anywhere.

My graphics card (physical) is not listed anywhere. It is like the computer does not recognize the graphics card.

Here are my specifics:
Computer: HP Model Desktop w2207h
System: Windows Vista 32 bit.
Monitor: HP 22” 1680 X 1050 resolution
Graphics Card: NVIDIA GeForce 8500 GT (current version: driver that will not install).

There is a windows update for my graphics card, but windows will not install this update. The update says: nVidia – Display, Other hardware – NVIDIA GeForce 8500 GT. I looked in my BIOS and under display it just says: PCI or PIC-E to select, but does not list any other specifications.

Can’t help but think this sleep mode occurred during a possible graphics card update. When I shut the computer off this might have happened. This is only speculation, but I know the computer went into sleep mode and would not come back out.

I have tried to system restore up to 4 different dates previous to this issue, yet the problem still persists.

I only know this information from looking at other posts. My knowledge is limited when it comes to hardware, graphics, or drivers. Only know what I am reading in forums. Anyone know what I should so here? Your advice would be much appreciated.

More about computer recognize graphics card hard shutdown
  1. OK I think my information was too broad. Lets start with trying to get the computer to recognize the driver, monitor, or graphics card. Perhaps a series of steps I can start with here. I did unintall the driver and then restart with the same monitor and it re-installed the driver. But I don't know if my sequence is right.

    The monitor plugs into the graphics card via an HDMI cable. How can I trouble shoot this? Should I uplug the monitor, shut off the computer, and reboot, then plug back in. I just don't know where to start or the sequence to try.
  2. Best answer
    Starting over here are my steps, perhaps my process is not correct. I am assuming I am missing lots here.

    1 . Open back of desktop and clean inside computer (very dusty).
    a. Removed video card and cleaned
    b. Visually inspected for loose wired or damage and reinstalled video card
    c. Put computer back together.
    2. Started computer without monitor plugged in.
    3. Shut down computer.
    4. Plugged monitor into HDMI area of video card and plugged in corresponding USB that also comes out of my monitor.
    5. Restarted my computer, this time monitor working but again still has the poor graphics display (the same problem).
    6. Looking into Device Manager for Driver:
    a. Went to device manager found disconnected display adapter (yellow icon) called: NVIDIA GeForce 8500 GT
    b. Right click driver>update driver software> Search automatically for updated driver software.
    c. Answer: The best driver software for your device is already installed. Windows has determined the driver software for your device is up to date. NVIDIA GeForce 8500 GT.
    d. Right click disabled driver> Properties
    d-1 Device Status: Windows has stopped this device because it has reported problems (code 43).
    d-2 Click: “check for solutions” to send data about this device to Microsoft and to see if there is a solution.
    d-3 Check for solutions answer: Could not load driver software. (I sent the report to Microsoft).
    d-4 Driver tab: Roll Back Driver is grayed out (I rolled it back previously) I thought it re-installed.
    7. What should I check next? Anyone?
  3. Took it to a tech, the graphics card itself (hardware) was fried. Got 6 years so can't complain.
