Good call, don't clear the cmos. You probably have a bad fan. It's not that uncommon for fan bearings to go bad. One of the three wires on the fan tells the motherboard the rpm of the fan. If it's running below a certain rpm, the PC won't boot in order to protect the cpu from overheating. You should be able to pick one up for cheap, around 10 bucks or so? Make sure you buy the correct size. These fans are measured in mm. Tiger Direct, 80mm case fan... 5 bucks.

When i put on my computer, this message apear : 511-cpu fan not detected. I have a Compaq Evo D510 CMT and i use Windows Xp. Thaks for the help


This will likely be caused by a loose connection, if you look inside the machine there should be a cable running from the fan on top of your cpu to the motherboard. If thats disconnected or loose then plug it back in and all should be right with the world!

First of all you need to install Vista on the 1-st partition. After done you can install linux on the free partition choosing manual instalation. The bootloader should be Grub, that works fine with Vista.

Compaq evo-d510-boot problem


What have you recently plugged in as new hardware ? this F1 response indicates that a piece of hardware is not properly configured to run , and F1 is the offered option to go to CMOS to complete the installation.A most likely item will be a USB powered piece of hardware.
