Re: Blank screen(beeping sound)
1 long beep is usually graphics card..

Re: Blank screen(beeping sound)
It's definitly a memory issue. What you might wanna do, is open your CPU and take out the memory sticks from the memory slots. After this, try either blowing or vacumming (if you have one of em small PC vacumm cleaners) the slots whcih contained the memory sticks. Also, dont forget to blow off any dirt that might be on the memory stick(s) itself.
After this, just insert the memory stick(s) back into it's slot(s) and try to rebppt your computer again. Most of the time it should work. However, if you still face this issue, then it means that your memory itself is corrupt and you might need to buy a similar capacity memory altogether.
As a side note, if your computer comes from a manufacturer like dell or acer, you might wanna get them to look into the issue if it;s still under warranty (or even if it's not). Certain "branded" computers have their own way of functioning. Hope this helped.

There should at least be a message on the monitor indicating there is no
signal coming to the monitor. The first thought that comes to mind if
all is connected would be that the power supply has failed. And maybe the graphic card.
Call also the DELL support in your country they will be glad to help and they probably know the fault.
that is the problem of cpu not a monitor to confirm disconnect signal cable and power on. monitor will show "no signal check signal cable" it means that monitor is ok and fault lies in cpu .then open the cpu and disconnect ram and listen the beep. contineus beep should be heard then ram is faulty replace it. if no beep heard then motherboard is faulty .
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
1. You can see images on the screen for a few minutes. That means there is nothing wrong with your computer.
2. When your screen goes blank, if you disconnect and then reconnect the monitor, it shows fine again for a few minutes before going blank (or dim) again. That means the problem is not with you video card.
3. It always shows the image after reconnection for exactly a few minutes before going blank again. yes? this means that there is nothing wrong with your cable.
Conclusion: Sorry, but you do not have many options. I bleieve that the problem is with your monitor that's going bad. Its far cheaper to get it replaced than to repair it.
Most screens will show nothing or go to power saving mode until the PC is turned on. The monitors need a signal in order to be 'active'. From your description it could just as well be a problem with the PC rather than the monitor. The easiest way to find out is to connect another PC or laptop to the screen or connect another monitor to the PC unit.
Did you try pressing the Del key or F2 key when you turn on the unit to get into the Bios?
I turned on my computer and the monitor displayed this message on the screen "going to sleep no input received". I checked the power cord and unplugged it, nothing. No lights are flashing or beeping sounds. The CPU is working just fine, anyone have any idea what to do
see there is power in monitor and check also that your monitor is getting signal from cpu just remove the data vga data cable from cpu and see is it showing any massage on screen like check signal or any other massage. and check your keybord also by pressing num lock key see the light is on and aoff when you pressing the num lock button . if nothing is happen that mean your monitor is not getting signal from cpu and it is not monitor problem
