Sorry don't know all know is a Dell. It was working just fine until I moved. Shut down. Took apart and boxed up. Moved down the road. Set back up a few days later and nothing. Monitor is working but not getting any info from PC. Keyboard and mouse inop also. Extremely confused. Know enough about computers but not an expert.

if thats the case either u have a bad psu or ur video card is not connected properly or its dying
make sure u connect the video card properly in its slot make sure the wires are properly connected to the video card.

"Sorry don't know all know is a Dell."

Go here for how to find the Service tag "number":

Tell us what it is.

If this is a desktop computer......

Unplug the case/power supply, or switch off the AC power to it otherwise.
Power off your monitor.
Open up the case by removing the left side panel as seen when you're looking at the front of the case.
Some Dell cases have a latch you must push one way rather than screws you must remove at the back of the case.

Check all the connections of the wiring to make sure they are all the way onto their pins and into their sockets, especially the main connector from the power supply. The wires close to the mboard going into the main power connector/socket should be more or less perpendicular to the mboard surface rather than at an angle.

Make sure all cards in slots are all the way down in their slots.

See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:


While you're in there, if the cpu fan/heatsink has mung (dust, lint, etc.) on it, clean it off, but DO NOT use a vaccuum cleaner to do that (they produce a tremendous amount of static electricity when running, and anything connected to them can discharge that to your components) - use canned air, or an air nozzle if you have access to an air compressor, or an artist's brush that can be used in small spaces, etc. It may be difficult to clean the top of the heatsink under the cpu fan - the most likely place to have mung on it - and the bottom side of the cpu fan blades unless you remove the fan. If you have a case fan, clean that too if it needs it.

Also check for mung on the video card fan and heatsink if it has that, and the power supply's openings / fan.

With the cover still off, restore the AC power, start the computer and make sure the cpu fan spins - if it doesn't spin, if you're sure the power supply is working okay, don't use the computer until you have replaced it.
If it spins too slowly, and/or if it makes rattling or screeching noises, most likely to be noticed when the computer has cooled to room temp, has not been used for a while, and then is started up, the cpu fan's bearings are failing - the cpu is likely to overheat as a result of that if it can no longer spin it's full speed - replace it as soon as you can.

If the computer still won't work normally after doing and checking those things, there are other things that could be wrong and that you could try.

If the problem computer is a desktop computer....

For more t-shooting info than is in response 5 above.....
See response 1 in this:

If there's nothing else wrong, the most likely thing is the power supply is failing.

That info assumes you have NOT installed ram that was not installed in the mboard before.
Installing the wrong ram modules can also cause no beep, the computer will not fully boot.

It is easy to test for incompatible ram (or damaged ram) that has caused your mboard to fail to boot.

Make sure you have a speaker or speakers or the equivalent connected to the mboard so you can hear mboard beeps (see your mboard manual if you need to).
Remove the AC power to the case/power supply.
Remove all the ram.
Restore AC power.
Try to boot.
If nothing else is wrong, you will get no video but you will hear a pattern of beeps that indicate no ram is installed, or a ram problem.
E.g. for an Award bios or a bios based on one, that's often a beep of about a half second, silence for a half second, a beep of about a half second, silence for a half second, continuously.
