Hello, i have a compaq presario cq42 and i have been using it for 2 years but this is the first time it happened the startup sequence was normal and in between while playing games it hibernates and when i switch it on again a message reads that my fan has stopped working!! 90B and it says it not wise to turn it on when i turn it on for some time the computer works without the fan working but after a while there are slow spins like in movies whn a dead engine is trying to recover and after a while it begns to work normally
