Stop: 0x0000008E error, help

I have made a mess out of my computer and I dont know what it could be.

Here is the story:

I bought a computer with Vista home. I was hoping to set it up for 2 monitors, but needed a second graphics card. A friend gave me one that he thought might be new enough to have Vista support (nvidia geForce 7300 gs), so I installed it and went to do the drivers and it said that it couldn't support the version of windows I have. This is where I should have stopped, but I didn't. I googled around and found this page (http://www.nvidia.com/object/winvista_x86_88.61.html) but I didn't bother reading the warnings that it was only for vista beta 2 and that it only added support for 7300 GT, not GS.

So it installed and told me to restart. When I did it loaded up to a blue screen with a bunch of stuff about windows having shut down due to a problem that could damage the system. It gave me an error at the bottom: STOP: 0x0000008E followed by a string of numbers. It also had an error pointing to a .sys file that I recognized was from the driver I installed.

So I rebooted in safemode and uninstalled the driver, turned the computer off, removed the video card, hooked up my monitor to the original video card (intigrated with the motherboard) and then turned the computer back on. It then gave me the same error only without the .sys file error.

Nothing I can figure out will fix it. The driver is gone, so what could still be wrong???

The error is also caused by a virus called HaxDoor virus this microsoft article pretains to this http://support.microsoft.com/default.aspx/kb/903251. I understand that the article dosn't seem to apply to vista but it may be something to check since I don't know your surfing nor your email habits. If not the main board or ram is causing the issues--- I've seen this if the speed between the motherboards chipset and the ram are not transferring information across the board properly ie. at the same speed and there is a tendency toward data corruption, just something to check hope it works out for you.....

Well just go to microsoft support and follow their direction in how to solve The The HaxDoor virus may cause a "STOP 0x00000050" or "STOP 0x0000008e" error message Here is the Link http://support.microsoft.com/kb/903251 Copy and Paste to your browser

It may be a driver related issue, is your sound and video card drivers up to date?

If none other solutions work then it is time to start hardware troubleshooting. Start with the RAM and then the hard drive.
