Since getting this PC, I've rarely had a time where it wasn't giving me some sort of issues. Usually the issues are to do with graphics, which makes it hard to do any 3D modelling, or Skeletor Hordak, sort or put up pictures, etc. Other times it's things like not wanting to boot... or not wanting to shut down... that sort of thing.
It even managed to kill the Ubuntu install I had as the back-up operating system. I have no idea how, it just stopped working.
So I've done another rebuild. I'm at least back on the net. Wish me luck.
PS I've recently managed to download all the Jean Michel Jarre albums that I had previously bought on audiotape years ago - listening to them again while I rebuild the computer has made it a much more pleasant task.
