Hi,
Thanks you for the reply. I followed the instructions and found I am using
Chip Type: Intel(R) HD Graphics Family.
I went to the intel site and used their driver detector, which suggested an update to the driver. I installed the recommended update but this has not helped. In fact, things are as bad as they have ever been. The computer always crashes 10 mins after startup with the screen suddenly freaking out and displaying the flashing colours and static I described earlier.
To make matters worse the computer has started freezing occasionally. I think this must be to do with the graphics because one time I got an error message saying the graphics driver had stopped working (or something similar to that). Another time, the computer froze but rather than re-starting it I just left it frozen for a couple of minutes and suddenly it came back and started working again! It just suddenly woke up and carried on working normally. Very strange and not something I have experienced before.
Do you have any more ideas for things I could check? It would be great to get to the bottom of what's causing this.
Thanks for your time.
