Apologies for my lack of posting which is all due to computers!
I bought myself a new Dell laptop which started turning itself off shortly after purchase. However, it re-started quickly and I foolishly spent ages transferring all my files over to it. Yesterday, 2 weeks after I received it, it crashed spectacularly and I couldn't re-start it! After a few hours I managed to get it going and have been scrambling to retrieve some of my files.
I don't want it repaired as I've read several horror stories about people who've gone down that path so wish me good luck in returning it to Dell - I've heard they can be very difficult...
I promise I will be back posting shortly!
