Hi when you say that your computer isn't beeping or displaying what exactly do you mean? Is there power getting to the system? Is the other light on the monitor? Are the drives firing up?

It may be that the power lead has come unplugged or, on some computers, the switch above the power supply at the back has been switched off.
Sorry to be vague but need more info.
Hope this helps

I turn the power on and my light stays yellow and the fans work but it beeps


The beeps you hear are BIOS Beep Codes and tells you what problem is keeping the computer from booting. We need at a minimum, the computer make & model or the motherboard model #. If you also know what BIOS it uses (Award, AMI (American Megatrends), Phoenix...etc), this was displayed during the boot process when the computer worked if you happen to remember it.
Once you know this we can find the code that tells what the problem is.

NO DISPLAY on screen but processor fan is work


If it seems like the computer booted up all the way except the screen is blank.

If so try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok and works, then the video card inside the computer is good, but the original monitor is bad. If the Borrowed monitor does not work, then the video card inside the computer is bad.

If it does not seem like the computer booted up all the way try the steps below.

When you plug in the power cord is there any lights whatsoever on the computer?

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 the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note 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 whatsoever when you press the power button.

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory 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 on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.

My pc dont show any thing axcept blank display with i tried to change graphics


Maybe one of your memory chips is bad.

If it seems to boot up all the way except the display is blank try the steps below:

Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor display the desktop then the original monitor is bad, but the video card inside the computer is ok. If the Borrowed monitor does not display then the video card inside the computer is bad.

If it does not seem to boot up all the way try the steps below.

When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power 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 the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two?

If it seems like the computer completed the boot process but the screen is blank, try the steps below.

The problem will either be the monitor or the video card inside the computer. Connect another monitor to the computer to isolate the problem. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays and works ok, then your original monitor is bad and the video card is good. If the Borrowed monitor does not work then the video card inside the computer is bad.

If the computer did not complete the boot process then try the steps below.

Why dose my laptop refused to open up anain


What is 3to3 info??

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?

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.

When i turned on switch dell vostro 230 it give no display and led colour is red


No Display, so does it seem like the computer booted up and is running except that the Display is black? Do you hear fans running, disk drive spinning, blinking lights or beeps?

I'm going to assume that in your case since you mentioned a red light that it is not booting up all the way. Therefore your problem is probably with the memory, the video card or some other motherboard issue.

Remove the Power Cord, Remove the Battery, Remove the cover that houses the memory on the bottom of the laptop then 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.

My computer does not display and yet it keeps beeping


There are some loos cables. Try unseating the RAM, clean it & put it back. Check that all power and IDE cable along with the 24 power pin is snug tight. Reboot and try to enter BIOS. Set evrything to default and try to boot in safe mode and then "last when it worked best". That should do it, else try booting from CD and repair the OS......sodeep

Hard Drive Alarm & Refuses to boot up


Either your OS is corrupted or you have a serious hard drive issue. Not uncommon for the latter to go without any real warning.

Get a hold of the diagnostics software for your drive and run it. Don't be surprised if it fails.

1 Long beep every 2 seconds


This particular symptom may reflect a problem with any number of components. A bad CPU or video card, for instance, may prevent the computer from booting properly. Often the number of beeps will clue you in to the offending hardware. Check your system or your motherboard manuals' troubleshooting sections for a list of beep codes.

If the beep codes indicate a memory problem, make sure all memory is properly seated and secure. If you've recently added new memory, make sure it's compatible with your system. You may also want to try cleaning the pins on each module and each socket on the motherboard.

If you have multiple memory modules, try to isolate any bad modules by removing all but one module and booting the system. If the system boots, turn it off, replace the module with another and boot the system again. When the computer refuses to boot, you've found your problem module.

Again, you may want to reorder your memory modules. Faster modules in the DIMM0 slot can cause a problem on some systems.
