Vista Killed my PC

My extra 2Gb Ram arrived and I immediately noticed two things after it was installed

Firstly, Vista didn't seem to recognise it claiming that it only had 3.25Gb. At first I thought the RAM may be faulty, particularly as the computer slowed down quite significantly which was a nasty surpise. WoW in particular became unusable as it was down to less than 10 frames per second even with all the graphic settings turned down.

Using my wifes machine with its Geforce 6600GT showed there was something seriously wrong as her machine was faster even though it was a lesser spec, and she had some of the graphic settings on WoW turned up. Though she was still complaining that her frame rate was slow when my machine was turned on.

After a lot of poking around I discovered this which at least explained the RAM issue frustrating though it is. I was almost tempted to try Linux on it instead at this point, as this didn't explain why the machine was so slow

At first I wondered if it was Symantec Antivirus that was slowing it down so I looked through it's logs to see what it was doing. It was then I noticed that Symantec was checking some strange looking IP addresses. A quick Google and I realised that I had somehow installed IPv6 on the machine. At the moment no one uses this (at least no one I know of) and so I disabled it. Miraculously the machine returned to full speed.

So the moral of the tale is don't install IPv6 unless you know you need to
