Turned on cisnet 80 gig computer and would not turn completely on, green light flashed for a couple seconds then red light stayed on. Opened cpu and fan was lose, reconnected and still would not work. Repair store thought that it was processor or short in mother board. Any answers? If I purchase an external hard drive case, what size would it be.

Dear Elvira, You have to disconnet your power supply from the mains by pulling out power cord then the open the side pan of your cabinet and locate the ram.remove the ram and resit it in another slot. then connect your power cord to the power supply of your pc then switch on. If the problem is not solved then again remove the power cord and remove the cmos battery from the motherboard and wait for 20 seconds,then put it back.and power on the system. if the problem is not solved then try with another powe supply.still problem is there then your motherboard may be bad.you have to replace the motherboard.
If you have an expansion slot filled with a video card, remove the video card (provided you have onboard video connector as well) then try to reboot. I just went through similar issues with an GForce video card, it went bad, but the machine appeared to boot althugh I couldn't see the screen. Removed the card & it came up using minimal VGA drivers provide with WinXP.
Obviously you cannot check the video driver if you're not booting up...and seeing the screen.
Find a buddy with a regular monitor and hook it up and try to boot. Dell monitors sometimes require their propietary drivers, so write down the model when you take your pc to a friend's place, and DL the driver and install it (provided you got it to boot up)
Do you have a windows XP cd?
If so you can try booting from the cd and running recovery console.
from recovery console type chkdsk -r
This should repair any bad sectors on your drive, allowing the drive to boot
(this scan may take some time)
If you are sure that the 110 volt power is coming into the computer then the most likely problem is that th epower supply died. Obtain a new one of the same or larger wattagge as the one you are replacing . It does nto have to come from the manufacture of the computer.
Is there more than one fan inside the computer? Did you double-check the connection from the fan to the motherboard? Sometimes a computer will shut down if it doesn't sense that the fan is turning on, to prevent the computer from overheating.
