Computer shuts down randomly, startup freezes, works later

[vanten]

Hi,

My computer randomly shuts itself off. It can happen after 15 minutes or up to 12 hours.

When I turn it on again it always freezes when the Windows logo appears, (Win7 and the part where the four dots become the logo).

If I wait for about 10 minutes, the computer will start up again, and we're back at the beginning again.

Any ideas?
