I'm having trouble connecting to the internet with my comp. The cables work and my wireless router picks up on the internet. I however can't get it to connect my comp. I'm also unable to do a system restore and the background looks like its running on XP or older. I looked for displays and themes but nothing. My operating system is Vista. I'm not really sure whats wrong i'm thinking i may need to delete everything and reinstall the OS but i'm not too sure how to go about that. Also my sound doesn't work and i get this weird error that tells me to check event logo 0x81000202. Any advice?
