Hi, Try do a CMOS reset on the motherboard. Remove the Lithium memory back-*up battery and let it sit for a while. If still a no go, borrow/replace the memory, checkif the CPU shows sign of warming up when powered on (this would indicate that it is indeed receiving power but just not booting). Try reseatting the video card if you've got one. Another that you can check is if the capacitors very near the top of the CPU are busted/swollen. Normally they should be shiny and flat with an X or Y mark. If they show signs of brownish color, cracked X or Y, blistering, swollen/bursted top, then you have a major motherboard problem which would require replacement. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards.

Dell Vostro 230. PC will not power on completely. When the Power button is pressed, the hard drive cycles for a second, it beeps, then shuts down again.

that's easy.
1 beep? you said BEEPS, so tell me its not one beep then leave off how many beeps in a bundle.
1 beep is RTC Coin cell dead. replace. it. page 7 in the manual
2 beep no RAM found
3: beeps. mobo bad. (or?)
4 beeps. 1 ram bad or more. try 1.
5: beeps same as 1 above usually. bad battery for sure.
6 beeps video chip failures. remove card if in PCI-e slot.
7: CPU cache mem. failures, rare but if VRM bad, not rare.
i guess you meant this, ?
Vostro 230 Mini Tower Desktop Computer this is really what it is.
That beep tells you , it sees something very serious wrong.
There are 2 possibles and many tests. do you want to learn?
forget the HDD, unplug it first , focus on FANS first.
both fans, PSU and CPU must run and stay running. my guess not.
  • PSU Bad.
  • or
  • MOBO has overloaded the PSU.

so all tests are to prove 1 or 2. out.
easy no?, a binary choice.
what a tech does next is strip the PC down.
pull out the cards that are in PCI (or express) slots. run now? fans?
pull the power cables from all SATA devices, hdd ,dvd, all.

unplug all USB devices, (overkill but is done for 1 odd case )
test the mobo with CPU in and 1 stick or DDR ram'
only then try each stick of ram 1 by 1.
this is all SOP, standard op. procedures in any shop.
if a module of any kind shorts the PSU sees that and shuts it self off.
the CPU if overheated, too shuts the CPU off, dead saving its own bacon.

if stripped down PC,
just mobo, CPU and any stick of ram makes the PSU shut off
we test the PSU by itself
it that passes the MOBO is bad.
never seen any CPU short ever, VRM's lots.

the power lamp has 5 states of color.
page 7 in your manual if you want to look.
solid blue is normal others bad, black or flashing color.
RTM pg 7.
here it is, at Dell, cost nothing to read.

I rebuilt computer with new parts, now won't start up. No POST. Power LED lights up, no cpu fans spin, no beeps. Psu works with paper clip test. New mobo, ram, psu, cpu.

Check display without cabinet maybe motherboard getting short with cabinet and try new Power supply check all the power supply connectors connected or not .

After turning on it turns off automatically after 3-4 seconds

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.Maybe your memory is bad or the memory slot is bad.Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

I'am working on ASUS P5PE-VM mobo, I removed the memory, video card and isolate the mobo away from the casing so no short circuit may occur during test. I plugged in the power supply and the front switch...

Clear CMOS or remove CMOS battery, Press the on off switch for 30 seconds.
Now go to BIOS setup,and set bios fail save default,and press F10>enter.If the problem same change the RAM if you have a spare.

Hope it helps.

Hi. my CPU (system) does not start. When i press the power button, the light turns on for a second then nothing happens.

Does the power supply fan spin when you switch it on ??

Do you hear a"posting" beep??

Does the CPU fan start to spin??

If no to all of these probably dud mobo.

Asus k8s mx not boots but fan rotates and without

Long beeps are saying 'no RAM'. Any beeps with RAM in place? Remove BIOS battery (silver) for 10 mins to return to factory defaults.

My computer system after turning on, turned off. cpu fan on and then off. mobo led is green (p4b533 asus). power is good, and unpluged all devices but no change! is cpu dead?

your cpu is probably overheating
turn off the power and unplug the computer and all periferals.
it may be dirty or the cpu fan may be going out. open the case, clean the fan with a can of air and cotton swabs. do not allow the fan blades to rotate freely when blowing them with air by holding them in place (or the bearing may go bad). you may also want to blow out the rest of the case as well and remove each card to clean them with swabs and air.
it will be slow work, but it can save you wear and tear on the entire system by doing so.
put everything back together and try everything to see that they work properly. if the problem persists, you may need to replace the cpu fan or risk damage to the processor.

No power up

Here was the fix for me. The machine refuses to boot if the video card is not functioning. It should have one long beep however to tell you that there is a video problem. Someone hooked up our speaker incorrectly though! So we got no beeps. Once the speaker was hooked up and the video card was replaced, all is well!
