Using Non-Dell monitor on Dell system

Could be a problem with the RAM. You can do a boot-up RAM test with a CD-ROM or USB stick using Memtest
Memtest86 Advanced Memory Diagnostic Tool

The Beeps are a beep code 4 means you have a ram read/write failure. Or a possible motherboard failure in that case you will need to contact Dell or replace it yourself.

Thanks for the tip, good work.

3 BEEPS -RAM

Guest Posts: n/a 01-24-2005 We had a power failure in the office this weekend. All the systems are back
up and running fine, except for the receptionists. It's a Gateway
Professional Series. P4 1.3 Ghz. It is giving me three beeps. No boot up
screen and no video source (monitor light stays yellow instead of turning
green). I looked up the beep code and it says three beeps means the ram
needs reseated. Which I have done several times. Also, I have just put in
one stick in difference seats. I have also reseated all the cards at least
three times. I have switched the jumper to try to boot into setup mode.
Nothing there either. Popped out the cmos battery and put it back in. No
good either.

Has all the ram been fried? The fan on the cpu is still spinning. The cd-rom
ejects. I can't hear the hard drive spinning. I guess I can swap the hard
drive for a different one.

Anything I'm missing? YEP

If an error occurs during startup that cannot be reported on the monitor, your computer may emit a beep code that identifies the problem. The beep code is a pattern of sounds: for example, one beep, followed by a second beep, and then a burst of three beeps (code 1-1-3) means that the computer was unable to read the data in NVRAM.
YOu can find complete table on Dell support site.

Most of such errors can be fixed with a system utility software RegInOut

If they're occurring right as you turn the computer on, it's your Power On Self Test (aka POST) letting you know. Since I can't be more specific, here's a synopsis of POST beeps:

One single beep followed by three, four, or five beeps -- System-board problems, possibly with DMA, CMOS setup chip, timer, or system bus. The computer usually won't boot when this is the problem.

Two beeps -- The POST numeric code is displayed on the monitor, usually nothing to be concerned about, but you might google the code on another computer and see what you get.

Two beeps followed be three, four, or five beeps -- First 64K of RAM has errors. Solution is to replace RAM.

Three beeps followed by three, four, or five beeps -- Keyboard controller failed or video controller failed. Either you won't be able to see or type with this error.

Four beeps followed by three, four, or five beeps -- Problem with serial or parallel ports, system timer, or time of day. Check your BIOS settings (usually F2 at start up) to make sure everything is correct.

Continuous beeps - problem with power supply. Probably won't do much with this error. At the very best, your computer will boot and run very, very slowly.

Hope that helped.

Using the manual for the Gigabyte GA-945P-S3 MB. Go to page 71 & you'll see bios beep codes for your board: AWARD BIOS Beep Codes 1 short: System boots successfully 2 short: CMOS setting error 1 long 1 short: DRAM or M/B error 1 long 2 short: Monitor or display card error 1 long 3 short: Keyboard error 1 long 9 short: BIOS ROM error Continuous long beeps: DRAM error Continuous short beeps: Power error As you can see there isn't a code for three short beeps. When you boot your system try to pause your boot up screen. See if the bios is reporting the correct total of memory in your system. Bios codes from the link below. http://www.computerhope.com/beep.htm#05 3 beeps for the AMI bios code reports Base 64K RAM failure. You can test your memory. Go to memtest.org Scroll down the site to just under the three screen shots. Download Memtest86+ V2.11 You have a choice in making a bootable floppy disk or a bootable CD-ROM disk. Once completed you boot your system to the testing program. Memtest will check your system memory. This should help. Thanks for using FixYa! Mike

Unplug power from the machine for a period of 5-10 minutes.

Plug it back in and attempt to boot. Carefully notice if there are any beeps again, and listen for pauses in between. Dell beep codes go in a three pulse pattern I.E. 4-Slight Pause-4-Slight Pause-2-Pause/ and repeat.

After this, you may have to open your machine and assure that everything is well connected.

There is a chance however that a major system component has failed and needs to be replaced.

Hope this helps.

If your computer is beeping at you, 9 times out of 10 its going to be an issue with the memory or video. (more often the memory) Try re-seating both. If your still hearing the beep fest, below is a list of the most common beeps and what they refer to. This will help you to find out what needs replacing.

Long beep followed by 3 sequential short beeps. This issue is linked to your Graphic card configurations
Short beep followed by three sequential long beeps You are facing a system memory problem
Beep- PAUSE- Beep- PAUSE- Two sequential beeps This error is linked to your CPU
Three beeps-PAUSE-Three beeps-PAUSE-Four beeps You have an issue with the video memory
Three beeps-PAUSE-Four beeps-PAUSE-Beep This is linked to an error with your Graphic Card
Four beeps-PAUSE-Three beeps-PAUSE-Beep You have a system memory problem
Five short beeps You are facing a problem with your CPU
Long constant beeps It’s a system memory problem
Short constant and high-pitched beeps The temperature of your CPU is too high

yes right click on desktop select properties then click on screen saver then increase wait time problem will solved
