Code 43 on graphics card, help?

August 9, 2013 at 11:16:59
Specs: Windows 7, Core 2 Quad 2.5GHz / 4GBs
My computer was operating fine, when one day I was trying out a new game from Steam. It was installing some software for first-time play (DirectX iirc) when it suddenly went bzzt and froze. After I reset my computer it has reverted back to basic graphics (800x600, no effects whatsoever, can't play games since the computer says I have no required graphic drivers). After I checked the Device Manager under the "Display adapters" it listed my "NVIDIA GeForce 8600 GT" as "Windows has stopped the device because it has reported problems (code 43)".

I've tried a lot of ways, uninstalling the drivers the reinstalling a new one, updating it, and even changed the card with an exact same working graphics card from my father's comp but with no luck.

Since my father's card didn't make any difference, this could be a software problem, how can I fix this? Thanks in advance.

Have you tried restoring your system prior to those changes?

Ok so next morning, I've decided to remove my graphics drivers with Driver Sweeper, and let windows install them then let it update by itself (which took about 1 hour), and then my computer started to lose signal after the "Starting windows" screen (whole screen goes black, says "Power saving mode" which means no signal).

Then I tried it in safe mode, reverted the comp and let it try again, which it said failed for a few times then finally succeeded. Card recognized, changed resolution, can play some games, was glad.

But now it'd take an awful lot of time between the "Welcome" and "Log in", and whenever I use anything that uses video (games, youtubes, twitch,...) my computer starts to twitch and lag and ultimately fail, and Windows would say that my drivers has stopped responding and recovered.

The drivers version is 320.49, and I'm not too sure but I think I've been using 285.XX then updated to 320.49 about 3 months ago. Will try to install older version.

I would start with the older driver as well to see if that resolves the issue. Then hide the newer driver from Windows Update. GL!

Hm...OK. Older driver didn't work, wipe them completely then let Windows update also didn't work. Reverting Windows to older date also didn't work, strangely. I've even tried installing a brand new Windows (properly backed up ofc), and tried all kinds of tricks to the drivers, which, did not work.

I wonder what's wrong?

EDIT: The graphics did work properly ONCE (I didn't even touch anything, just started it up and it just worked), then I shut it down and next day it went back to crap again.
