Recently my boyfriend has been having problems with his HP DV5000 Laptop. It started off freezing, and now it shuts down randomly anywhere from a few seconds to an hour after start up. It doesnt seem to be an overheating problem, seeing as how he tries to boot it from cold and even with a fan running it shuts down. After repostitioning the RAM, the computer would stay on longer but now it wont indentify the WiFi signal or internet at all, as if its not an option. We have cleaned the inside and the fan seems to work fine aswell. Any help would be appriciated.
