Computer will not show any video, Power lights on front, power lights on mother board, series of 5 long (i think they are long) beeps.

Is the computer completing post? This is indicated normally by a single beep after the power button is turned on. On most computers the beep is proceeded by a post screen with the manufactures logo. If the computer is not getting this far, unplug everything but the memory and video. This should cause the computer to give a no hard drive or OS error. If not pull all the memory, this should cause the computer to give a series of beeps (because there is no memory installed). If this does not work either, you could have a bad mother board or power supply.

Hope this helps

I think cleaning the ram copper lid may solve the problem.

This could be lots of things (bad HD, bad Mother board, bad RAM,etc...) first you need to narrow down the possible cause, open the computer, take out every thing that can be unplugged (I MEAN EVERYTHING) RAM, PCI cards, VIDEO cards, all storages HD, CD ROM, etc... just leave the CPU and power supply plugged in, than power up the computer and listen for BEEP's if you hear a series of BEEP's this means the CPU, power supply and mother board are GOOD, than (with power OFF each time) re-install the components you taken out (ONE at a time) to see which device causes the system crash... I've seen a modem card causing a system mall function once rediculous but true...

Good luck!

there are several things that could be causing this issue. 1) could be the power supply has died. It may get some fan spin but never power the motherboard. This would cause what you are seeing. 2) could be the motherboard. If the video is built into the mother board it either could be the adapter or the motherboard itself. If you get no beeps or drive spin noises it is probably either the power supply or motherboard. ( I would try to test the power supply first, very often that is all the problem is, just happen to my dad's computer) 3) if you get some beeps and lights it could be just the video card. If you have one on the mother board try plugging another into one of the slots.
Those would be my first 3 guesses, good luck

System Beep Codes The Inspiron™ 531 / 531s system can emit a series of beeps during start-up if the display cannot show errors or problems. These series of beeps, called beep codes, identify various problems. One possible beep code consists of repetitive three short beeps. This beep code indicates the computer encountered a possible system board failure.
The series of beeps has a 3-second delay before it repeats. The series and delays continually loop until you press the power button.
Code Description Suggested Remedy 1 BIOS ROM checksum in progress or failure System board failure; covers BIOS corruption or ROM error 2 No memory modules detected

1. If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.
2. If available, install a good memory module of the same type into the computer.
3. If the problem persists, contact Dell.

3 Chipset error (North and Southbridge chipset, DMA/IMR/Timer Error for Intel® platform); chipset error System board failure. Power LED is blinking amber. Time-Of-Day Clock test failure Gate A20 failure Super I/O chip failure Keyboard controller test failure 4 RAM read/write failure

1. Ensure no special memory module/memory connector placement requirements exist.
2. Verify the memory modules you are installing are compatible with the computer.
3. If the problem persists, contact Dell.

5 Real time clock failure. Possible battery failure or system board failure.

1. Replace the battery.
2. If the problem persists, contact Dell.

6 Video BIOS test failure Video card failure 7 CPU cache test failure Processor failure

> power led,

Runs to the LED (Light Emitting Diode) labelled "power" on the front of your computer-case

> H.D.D led,

Runs to the front-panel LED that lights-up whenever the Hard Disk Drive is being used.

> reset sw,

Runs to the "reset" button on the front panel.

> speaker

Runs to the internal speaker

> s/b sw

Very briefly touch a metal-tip screwdriver between these 2 pins.
If the computer powers-on, you've found the "power" connector.

is there a post beep when the pc is switched on. check the memory if it is a beep beep beep sound , also disconect the hard drive, dvd drive, floppy, and any usb devices and see if it boots up. if that fails it does seem like the mother board, also check the cpu fan has it stoped. also find out the power switch conector on the mother board, from the base unit switch to the mother board. also chech the power connector from the power supply to the mother board , on newer boards there are two that go to the mother board its self , a big one and a very small one .

1. Your smps is OK for power supply
2. check the beep sound for RAM and Video card (If it is long beep the RAM is having and short and frequent the Video card) o

3. Remove RAM then start ssytem see the response shoutdown, clean the RAM place it back start the ssytem
4. Remove the CMOS battery or short the jumber for any setting in BIOS start the ssytem
5. Disconnect all the cables connecting motherboard including Hard disk except SMPS power supply to Mother board

• Bad video card - 1 long and 2 short beeps
• Bad power supply - 1) continuous beeps, 2) non-stop short beeps
• Bad memory - 3 short beeps
• Bad Motherboard - 1 long and 1 short beep
• Disk drive related problem / Video card problem - 1 short beep then nothing happens

Either motherboard, ram module or if no power at all sounds more like a power supply. If the computer has on board video you will need the ram to get any video. But with it removed the board should still beep if the case speaker is connected to the board. Have seen a lot of these less expensive motherboards fail. If there is no power up at all or lights coming on on the case I would think it is a power supply problem. Happens all the time and quite easy to repair. Just put on a new power supply.
