I really don’t know what happened. My vista started to automatically update so I restarted it to apply the update. But after that, it lost its ability to run games smoothly. Now I’m restricted to 2-D games as anything 3-D is now too demanding for it to run. I de-fragmented it, I scanned it with freeware anti-virus software, I used the disk-cleaner tool, I removed any un-needed programs and its still very slow. I have no idea what the problem is, and if anyone does, I would be very grateful to know…
