Blue screen- no errors message after system restore

[Draka]

My son's laptop was running very slow, so I tried system restore at a point recommended (critical update point). Now all I get is a blue screen, no messages and no windows sign appear. Any suggestions what might have happened and how to deal with it?

You have most likely that you have corrupted your windows. I would reinstall it with a cd if you can. Otherwise you will need a new laptop

I'm going to agree with Velo3100
