Not sure if this really belongs in CPU and Components because it could be the motherboard.
When I turn on my laptop (Dell Inspirion XPS Gen 2) the power switch will turn on and I can hear a fan turn on as well, however the LED lights on the sides and the monitor itself do nothing at all. If I leave it on in this state after 10~ minutes I can turn it off and then turn it back on quickly and it will then usually turn on and act normal. However I have noticed if I do anything that requires more cpu power than talking on aim or surfing the web the laptop will become very hot on the right side and the fan on the left side will turn on full blast as if a fan on the right side isnt doing its share of the work.
My laptop knowledge is near nothing, so I hope someone can point me in the right direction to what needs to be replaced or corrected.
I've seen many Dell's with fans that were about to fail.
Go to Dell website with your service tag handy.
You should be able to find a replacement fan and review the installation instructions.
These should be easy tro replace.
