Windows Vista Keeps crashing, complete pc shut down

I run Vista. My computer keeps crashing. All programs shut down soon after starting my computer. Takes around 10 minutes before total shutdown. How can I fix this?

Also, I am having a problem with being redirected to sites. Any time I go to a search engine and after I select a link, I am redirected to spam. What can I do?

Thanks so much!
