    System won't boot


    The processor fan comes on for a few seconds, then goes off and repeats this action. No post beep heard.

    Did you add any new hardware recently ? Also try filling in complete system specs in your profile. Could be Bad RAM or Power Supply.

    Dell Desktop i7, 18GB ram, 1T Hd. Went to boot it and I heard the fans spin up, then stop, then spin up. It never got past that.

    Model of the Dell so we can look at it better to determine. If no new hardware was added and the case was never opened lately as said it can be a bad memory module (RAM) or a bad power supply (PSU). Try taking out one or two Memory Modules at a time and see if it boots up till you determine which stick maybe bad. Without knowing the system model not sure type of RAM used and how many modules.

    Could be bad Power Supply, RAM, or faulty motherboard. Also could have an issue to where there could be a ground issue.

    First thing you need to do is unplug the computer, and then make sure all of your hardware is fully seated "RAM, Video Card, any expansion cards, wires, etc", and also, I recommend unplugging your hard drive. Plug the power supply back in, and test.

    If that dont work, start taking out the memory sticks out and putting them in different slots as jds63 pointed out.

    Hope this helps

    I would try taking one Memory Module out from DIMM 2 and then try booting, if that does not work take out Memory Module from DIMM 1 and put the other Memory Module from DIMM 2 in DIMM 1 and try booting again. Look here, page 14-15 http://downloads.dell.com/manuals/al...nual_en-us.pdf

    Other then that chances are as said by me and others, bad Power Supply, CPU or motherboard. Most likely a bad RAM Module, even reseating them may help.

    What I've done to determine bad memory sticks or memory banks is to remove the RAM sticks and then power the computer on. I do that to try to get post beep codes. If it doesn't beep, then it's PSU, CPU or Motherboard that's faulty.
