Hi, I've searched for a similar problem on your pages but without success.
The computer is a Dell Vostro 1000 (laptop) running Vista Business. It has V1000Turion TL60 2.0Ghz Dual core.
Yesterday evening I loaded MS Security Essentials and did a quick scan using it. I then did some tidying up using CCleaner, after which I continued using the computer with no problems for about an hour.
This morning the computer will not start up. The screen is lit up and the cursor arrow is present and responds to the pad but that is all.
I have inserted the OS disc and this can be heard spinning but there is no other reaction to it.
I think that's all the info I can provide. Don't have a clue what to try next.
Regards.
