I'm sorry to say this usually means hardware falure if your PC was working fine before. Here is a link to the Dell support site. At the bottom of the page they explain what the various beep codes mean. http://support.dell.com/support/edocs/systems/dim3100/en/sm/adtshoot.htm

Most laptops use beep codes to isolate startup problems . You may hear something like beep beep-beep or a combination
The beeps tell you why it's not starting ... if you hear the sounds then the manufacturers web site will tell you what the code you are getting means

Power went out overnight. went to start cpu in the morning nothing but monitor light is on. On the back of cpu tower green light is flashing. Whats the issur anyone?


It could be anything but probably a power supply error.
Power it down, wait 1/4 hour and power it up. Listen for the error beeps and that will tell you where the fault area lies. Error codes are listed in your manual for the mother board or indeed with the manufacturers web site.
If there are no beeps, replace the power supply and try again.
Hope that helps.

My pc beeped twice and nothing came


Lack of video signal is usually 1 of 3 things, Power supply (PSU), Video card or Motherboard (mobo).
Situation #1: If you get a blank screen and no sounds or movement it either indicates that the power supply unit (PSU) has failed or something on the motherboard has failed, preventing normal startup.
Situation #1A: You might get some power lights coming on and some fans spinning but the video output does not happen, usually indicates that motherboard or PSU is going out or has gone out. Occasionally it will be due to a weak (damaged) PSU.
Situation #2: If you get sounds (normal Windows startup sounds) and lights but nothing on the screen then it indicates a failed or loose video card.
Always try a different power outlet that you know is working. (Eliminate the easy stuff first!)
If it is out of warranty, try opening up the case, with the power off, of course. If you have Sit #2 and have a video card that you can reseat (take out and then put back in) try that. If it is onboard video then you may have to buy a video card for it.
Also take this time to inspect the capacitors on the motherboard (they look like tiny soda cans) and check for tops that are bulging, swelling or leaking anything. Capacitors should be perfectly flat on top. If you find these then your motherboard is bad (well technically the capacitors on your motherboard are bad). The bad caps will need replacing to fix (not a job for an amateur). If it passes the visual inspection then it may just be your power supply is bad. Notice that a bad PSU does not mean you are getting no power, just not enough to start and run the computer.
A few years ago a company stole the recipe for making capacitors and started making their own capacitors at really cheap prices. The stolen "recipe" was not complete and not correct so these caps started failing after about 2-3 years of use. Emachines, DELL and Gateway were the computer companies most affected by the bad capacitor issues, although any of the big companies could have the same problem. These bad caps also affected power supply makers.
Do you hear anything else during startup, beeps, fans or drives spinning, lights on the front or back of computer flashing or lit up? Do you hear the Windows starting sound?
Let us know more then we can troubleshoot better. Do you have the 4 diagnostic (A,B,C,D) on the rear of the machine? What is the front power light on the CPU doing?

BEEP


Did you try resetting your BIOS. If you havent then reset your BIOS and try to start the computer again. If it doesnt start then there is problem with memory.
Try another slot(PC has two slots for RAM right) if it still doesnt work then you may have to try replacing your RAM.

When you press F10 to enter the set up nothing happens, is that correct, and what does the beep sound like? Also, does it beep if you don't press anything, and after the initial screen with the F10 message, what does it do?

Laptop does not start; long beep heard, no display


Have you attached an external monitor prior to turning it on?

Also, does it power up with battery and ac adapter? Try taking the battery out, and also just using memory in 1 slot.

Let me know

Good luck
