If beep sound repeating continously then you check the ram if it continue replace it .and one more reason if it is in case if it is beep at first and stops then it is due to display problem so check the display cable

When you first power on a computer it checks itself out for proper operation even before you see anything on the screen. This process is called Power On Self Test, as no video is yet displayed and moreover there may even be a video problem the computer sends out beeps over its internal speaker to indicate its status. Usually you will just hear one beep then the computer will "come to life", if however there are any problems you hear a series of beeps. For a description of these beeps and what they mean please click here. Hope this helps !!

The cpu is running,the motherboard is with green light inside,but the monitor blanck

what king of monitor you have., crt or LCD, does the monitor led indicator has a green light, is there any beep when starting the cpu? how many beeps you have heard when the cpu was starting?.

if there is no led indicator light in you monitor the posibilities of that is the monitor was the problem.
solution: try to check your plug in monitor if it is properly inserted in the power plug or in the vga plug correctly.

if when you power the cpu and your monitor led indicator, turn green and back in the standby mode. listen to the beep sound of cpu if theres any.
solution: try eject the mem card. in the slot and clean the contact with the eraser. and put it back into the slot again after you clean it.

Dear User,

Please refix the is display cable properly and check if the issues resolves.

Kindly check if any beep sound comes. To check is the system board is fine. Please press the Num Lock for 2-3 times and check if it responds(Led On/Off)
To check the monitor status, please remove the display cable which is coming from monitor and connected with System(Cpu), if it displays the message on screen then it passes the monitor test and indicates that Monitor is fine.

Please share the result.

It looks like issue with either mother board or processor.
open the box and remove all memey and power it on. if it makes a beep sound, there is no issue with processor, else we suscpect processor. If it make beep sound, it might be mother board issue. And for checking monitor working condition, remove monitor data cable and see no cable connected messages comes in monitor or not

My monitor is not responding to anything. what can i do aside from rebooting?

do you see the light blinking in the monitor? I mean the POWER led light up? If so, then the monitor is ok and is working good. It is your CPU which has a problem and not sending digital signal for the monitor to display.
Try to turn off your computer. After 3 minutes turn it back on. then notice if you will hear a short beep from the CPU. That signals a successful video initialization. If you went through that process, then your computer will get back to life.
However, if you dont hear a short beep from the CPU, then definitely your CPU is frozen therefore there is nothing to display to the monitor.
You need to open the CPU case, pull out memory modules then plug them back in. Then try booting.
If not successful, try to open case and pull out the processor. Put it back in after 30 seconds. Try booting again.
Do ALL THESE while your PC is UNPLUGGED.
Good luck.

When I boot my PC up I get a blank screen and a message saying no signal then the screen goes into standby mode

OK, it's gonna be one of these 3 things :

1. The cable linking your CPU to your monitor might not be properly plugged or has been damaged. You should hence ensure that the connection between the two devices has been properly done and that the cable’s state is fine. 

2. You might be facing a problem with your monitor if the CPU makes a single beep error sound when you switch on the system. You can check whether the problem comes from your monitor by testing it on another CPU. If you still have “No Signal” error displayed including the error beep, I would strongly suggest you to try to get your monitor fixed by a competent technician or to get a new monitor. 

3. If you receive several error beeps when starting the computer, this might be linked to a graphic card dysfunction. You can refer to the motherboard notice or check that the connection has been properly set

Continuous Beeping, new PC

Continues short beeps... means a short OR no power OR loose card OR system board.
Test it without the keyboard and mouse too. Just the Processor with heatsink, motherboard, memory and Video card.
Now add the keyboard, no mouse yet.
Check also the voltage of the CMOS Battery it should be 3V.

keep me posted for the result... count also the beeps.

No any display in the monitor, no beep of the RAM while CPU fan is running

Check your power supply. It sounds like you have a bad power supply. Even though the computer powers up, it does not mean that it's good. I have had this problem before, and almost 9 out of 10 times the power supply had gone bad. Just try a different one and see. hope this helps you.
