First, let me outline my specs:
OS: Windows XP Home Edition
Processor: Intel Core 2 Duo T7250 @ 2.00GHz (2 CPUs)
Memory : 1022MB RAM
Graphics Card: NVidia GeForce 8600M GS
Operating System: Windows XP Home Edition (Downgraded from Vista)
Cutting edge stuff.
Anyway, onto my problem.
I haven't had any problems in over a year. But a few days ago I was playing a game and I Alt-Tabbed out of it to Google something. As I clicked on a Firefox tab, my screen froze, speckled with green dots, and I got a BSOD. Sorry, I didn't get a good look at it.
The next time I ran the game (American McGee's Alice, in case you're interested - I'd been playing it since Saturday with no serious issues), once I loaded my save I got a BSOD almost instantly, citing nv4_disp.dll. My old favourite. Now Windows wouldn't boot at all, unless I went to Safe Mode. The XP loading screen would come up, but it would never get through to the login screen - I'd get a black screen with a blinking cursor, then my machine would restart.
I figured my only recourse was to bugger around with my NVidia drivers in every way possible. I downloaded the newest ones and installed them. No help. So I uninstalled all of them and reinstalled the basic ones that are bundled with the machine.
It worked! Kind of. It would get to the login screen, but after a few seconds I'd get the same old black screen with cursor. I was perfectly able to login, but it would still reach the same result. Seemed like a time issue.
What now? I uninstalled all of the drivers, on the advice of some website somewhere. Perfect! It worked. So I ran the same game again. Opened my save... Save freeze as the very first time - Green dots, but this time no BSOD. Just a restart.
And again Windows won't even reach the login screen. This time I uninstalled again (The drivers having regenerated somehow) but I didn't restart when prompted. Now they tell me that I can't uninstall them because they're required for startup. My mind tells me the next best thing is to disable.
So. Now I can run Windows freely. I've realised that I can do whatever I like with my graphics drivers (I've now used Driver Sweeper to clear away old traces and installed the newest drivers available - 195.62), but as soon as I enable the Display Adapter, I'll get the black screen again. It doesn't seem to matter which version of the drivers I use, enabling the adapter kills my system.
My comp works now, but I'd rather play games again one day, and every time I scroll I get that slow 'repainting' effect that causes headaches and mild blindness, so I figure I should try and and get the display adapter working again.
At some point during all of this, I updated my Chipset drivers (Intel ICH8M - 965M Series) and my Audio drivers (Realtek HD). No effect on anything, but I wasn't expecting much.
Can anyone help?
Thanks in advance,
