I use vista (home premium), and keep it all updated and antivirused etc, and I can't think of anything that has changed immediately before I started having this problem.
Two days ago, my laptop started freezing, and only a hard shutdown would allow me to do anything with it. It has now got to the point that it only functions for about ten minutes after startup, and then no matter what I am doing, or if I am not doing anything at all (i.e. even if I have no applications open), the computer will just freeze. Sometimes the mouse cursor freezes as well, sometimes it moves but I can't make it click anything. I can't open task manager while it is in this state.
The computer has become slow to open programmes, and I get a lot of 'not responding' in thunderbird and firefox, often just before a freeze. The computer itself is not that old, only just under three years.
Please help a clueless desperate person! I have no idea what's going on and no idea how to find out!
