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

Remove whatever USB cables in the front USB ports below the DVD. Then try starting it should work. If not remove USB from the rear one at a time. Once it restarts replace USB cables into ports.

Has anything changed since it was working last? check that first
Next -- the Beep codes indicate a hardware problem --the PC was unable to POST(Power On Self Test-)-but DELL's beep codes closest to what you described is either 1-2-video card not detected or 1-3-1-1 which is Memory (RAM) error adn the PHEONIX beep code of 1-3-2 is Memory error also-- so be sure all cards and chips are seated properly--I dont think its the hardrive --a PC can still boot and POST without a hardrive.

Press pwer button and all that shows up on monitor is flashing line in left top corner


Assuming you have windows it means windows is not started therefore the system has failed a BIOS check. You have 4 error lights on the front of the dell, can you tell me which ones are lit and what colour they are, also does the machine beep when starting up - is so the number of beeps is important.

solutions

• Ensure that no special memory

you are installing are compatible with
your computer.
• Reinstall the memory modules and
restart the computer.
• If the problem persists, contact Dell. (if have warranty)

After beeps 3 times my desktop will turn off. and show light no 3 & 4


This could be due to many reasons.
1.DUE TO VIRUS INFECTION. Scan your pc for virus infection by running full system scan through your antivirus.Also update your antivirus.
2. DUE to irregulated power supply, your processor temperature can change abruptly,which can lead to the problem u have described. U can check the processor temp. through BIOS.
3.Finally check and re-install your window drivers.

When I turn the hard drive on it beeps 6 times intermittently and doesnt boot up as normal. The monitor is switched on but there is no picture. I tried another monitor with my hard drive and that worked...


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.
