Hello,I have been receiving a message that I had a fan failure on bootup and to hit f1. But my computer has been working fine for over a month. Well tonight i decided to open up the cpu box and look at it so I can order the fan kit and I unplugged the fan to see how to get it out. Well i plugged it back in and now my computer won't turn on at all. Is this because the fan failure?and it will not power on because i unplugged it and now it reads it won't work at all? I have to get this fixed immediately i wo9rk from home from my computer and this laptop that i am using to write this does not have enough memory for my job.

Did you take the fan and the metal heat sink under it off? Or did you pull everything out including the CPU that might be stuck to the underside of the heat sink?

Computer was working fine, then when I turned it off I Took out the fan and also took out the heatsink and the foil is stuck to the heat sink not the cpu box, put everything back on and now it won't turn on at all. I know the fan is not working at all the green light above the mother board does show green so I am wondering since i unplugged the fan if it will not power up now until I replace with new fan. as far as the heat sink i just put it back on is there anything i need to do to it as well? do you think if i replace with working fan it will power up?

In general the heat sinks are not designed to be removed and replaced without the reapplication of new "heat-sink grease" or a new "heat-transfer pad". But, this problem should only result in overheating and computer shut down.

I would examine all the wires to see if any were unplugged. You might have two wire harnesses plugged into the motherboard. One long plug with 20 or 24 wires and one square plug with 4 wires. You might have moved one of these during your work inside the computer.

I would call Dell and see if they can help. Dell motherboards often use special heat sinks and fans. You will need to order a replacement from them.
