Mouse keyboard and monitor dont work upon power up


If it seems like it booted up all the way except the screen is black try the steps below.

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

If it does not seem like it booted 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 so the computer 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 laptop 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 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.

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.

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?

ET1161-07 onboard Video gone bad. I tried a Gforce 8800GS 384mb card, that works, and I have no video, 1 long beep that never stops. Ican't get into the bios with the onboard video or the new video and...


Hi.

One continuous beep means that you probably have not put the graphics card in the PCI express slot or there is a short somewhere in the system.

Follow these steps to try and resolve the problem:

Remove the power cord and the video lead from the back of the machine and then remove the side panel to reveal the motherboard.
Remove the graphics card and take a look at the PCI Express slot for dust. If you see any dust get a clean, dry paintbrush and clean the dust from the slot and then blow on the slot to remove the rest of it.
Next look at the brass contacts on the graphics card and clean then. Re-seat the card making sure that it is fully pushed down in the slot.
Check that any other cards you have installed in the machine are seated properly.
Without putting the side panel back on, connect both the video lead and the power cord and turn it on. DON'T TOUCH ANYTHING INSIDE THE COMPUTER!!!

If the computer boots up turn it back off and put the side panel back on. If not then please post back telling me what the computer is doing.


Good luck.

i seem the power supply gone bad, it is hard to say what is the problem actually, you need to check all of your devices(processor, ram, video card, motherboard and power supply) to some other system one by one for confirmation.

Constant beep and wont boot up


that means you have a hardware failure, if it continuously beeps that means the gfx card ( video card) is not being recognized by the motherboard, but also it could be your ram. And Did you overclock your pc? If so, you failed at the over clock and you need to reset bios to defaults by taking out the lithium battery while its disconected from power. Let pc site for 20 min with no power and battery, once 20 min pass put battery back in and power up pc. Still no boot and constant beep make sure all cards are fully seated ( video card, sound card ect. ) and make sure the power cables are fully inserted as well. hopefully no hardware has to be replaced

Constant beeping when powered up, no display


If the beeping is constant, check your keyboard for any keys that are stuck in the depressed position.

I just put a new bios battery in my Acer RC900, now I get constant long beeps


Most Long beeps are related to video problems. Ive nudged my video card out of place more than once and that is what it does to me.

Dell precision 3100 machine will not boot up


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

Video card


Working and Working properly are 2 different things.

Unplug your pc. Let it set for 1 minute.
Plug in your pc.
Press the power button.

Does your monitor do anything?
No? Then it doesnt work
Yes? Then it works

If you get any video such as your BIOS or WIndows loading then the video card is fine.

Also, if you boot and you hear noises like:
Long Beep short Beep short Beep short Beep
(Long short short short)
Then your pc is not detecting the video card.

A looping beep


Try disconnecting power to all your drives. It's possible one of the drives has a short that is bringing down the power supply (most power supplies will shut down if they sense a short, to avoid damaging your computer). If it's not that, it's either a bad video card (reseating obviously won't help if the card's damaged) or a bad motherboard or processor. If you have another machine you can borrow a video card out of, you can test that. Otherwise, you'll have to replace the motherboard and processor. Never replace just one of the two, as one can damage the other and it's not worth frying your new equipment by putting damaged hardware in.
