Beep code and nothing on monitor

When power is turned on all I get is a long beep repeated every few seconds and nothing on the screen.  I hooked the screen up to another computer and it works fine. I unplugged from the motherboard what I think it the power supply (wires in a bundle go to the power supply and also to all the drives.  Any ideas?  If I could only get info on the screen I may be able to fix it, lol.  Thanks in advance for any help you can give.

Re: beep code and nothing on monitor

You may be correct about it being a power supply but you need to know the manufacturer of the mother board and check out their website for error codes. Please list your motherboard name and model. A power supply is cheap enough to test your system and you can return it if it does not work. They are real easy to replace too. Unplug your system and leave unplugged for half hour before opening your system. There are 2- 4 screws on the back upper part of your computer and a harness connector that the power to the motherboard goes. It's a good idea to bring in your old power supply to match it with a new one.

Monitor screen is black but computer seems to work

That is not enough info, please provide more info so people can understand the issue better. For example, describe what you do and see step by step. When you turn on the machine, after a few seconds it powers on, it should run Power-On-Self-Test (POST) which will end with a beep telling you everything was OK. If you do not hear any beep, the problem is likely to be inside the case, bad video card, motherboard, CPU, etc. Typically bad RAM or Video card will cause a series of quick or long beeps (different for each motherboard) to indicate where the problem is. Bad CPU generally do not generate a beep code and most motherboards also do not give out a beep for motherboard issues, naturally.

If you hear that beep but see absolutely nothing on the screen from the moment you turn it on, then check to see if the status indicator light (assuming it has one) changes color or not:

A) If the light on the monitor changes from red/amber to blue/green but you see nothing on the screen then either the video resolution and/or refresh rate is unsupported, video drivers are faulty or monitor itself is bad.
B) If the light goes back to red/amber or stays that way from get-go, then there is no connection, monitor cable is loose at either end or bad/supported.
C) One other possibility would be the input selection on the monitor which is set to "Auto" by default but if it was manually changed to DVI for example and you are now using a HDMI cable, monitor would not automatically change this setting thus not receiving the signal from the video card. You can check this using the menu buttons on the monitor itself.

This is a generic troubleshooting ideas I just shared, more details you can provide, the better people will be able to assist you.

Screen gets black

Typically the graphics card went out. Other possibilities include, loose monitor cable or short in the cable, or incorrect graphics driver installed or missing, or monitor is shot (least possible). Things to look for: When booting up are you able to see words in the monitor or is there a series of non-regular error code beeps? If beeps then most likely your graphics card is either loose or fried, or incompatible. If you it works fine, but the light on the monitor turns orange and screen goes black, then it's most likely a loose monitor data cable or there is a short in the cable, or monitor's power cable is loose. Then check both connections, power and data on the monitor, and also where it hooks to the computer make sure it's screwed in snug.

Computer won't start, solid amber light, no fans, no keyboard, nothing. There is power to monitor and modem. What's wrong and how can I fix it?

That my Friend is the Yellow Light of Death, anyway turn on Your PC, as it starts You will here some beeps especially on a Dells. Count the beeps , there will be a slight pause so it will beep once then pause then beep again. Count the beeps and that will be Your code. Go to Dell Support site and look up code. Most of the time a Yellow amber light means that there is trouble with Your Motherboard but thats not to say its the Motherboard itself, during a power outage with no surge protected, it could have possibly burned out Your RAM, Processor, Heat fan, even the power supply itself. So look up the code and at least You'll have a better chance of finding the solution, Good Luck

Monitor shows nothing on screen, power button on solid, none of other buttons respond.

plz try by removing the connector of the monitor from the back of cpu while keeping your monitor power on. if you get any message in the monitor then your monitor is ok. then open your side cover and try by resiting the ram, you have to swithch off your pc before opening your side cover. If you dont get any thing in the monitor then *********** board is having problem
