No video on monitor

When I boot, there is no video on monitor. I changed video cable, but suspect it might be my video card. May I order a new video card? If so, what part number would be the best?

Thank you,

Usually this problem comes due to static on the motherboard..

do the following..

1) unplug all the cables from the back of the tower incuding the power cable..

2.) press and hold the power button of the tower for 15 seconds.

3.) just plug in 4 basic cables that is monitor, power, keyboard and mouse.

switch on the computer it should work.. if not let me know with the model number of you HP CPU

All the best

Provide detailss about your system
before you conclude that its an issue with video card
do the following steps
disconnect the monitor cable from your computer (BLUE VGA CABLE)
if you get a power on self test
a colored box moving all over your screen
it will make sure the monitor is working fine
if you don't get any display on monitor its a monitor which needs to be replaced

for part number provide info regarding your computer
if its a DELL provide the service tag
you will find a bar coded sticker which has a 7 digit alphanumeric number it clearly says SERVICE TAG on a DELL computer

In terms of troubleshooting can you provide more detail
What specifcally happens when you boot the machine up. Does it have a black screen that has typing on it which then changes to pink later? Do you see any writing at all while it is booting?
Does the hard drive make the usual noises during the startup?

Hook a spare monitor to computer, if okay! the original monitor is the issue, if symptoms are the same, it means the Video Graphics Card in the computer is bad, but to be sure, change video cable from the computer to the original monitor, if okay! video cord is the suspect.

How to install a video card,

Find the drivers for your video card that you want to install and get them on the computer before you change cards. Once the driver is on the computer, then you ready to begin. Don't change the drivers to the new one just make sure that its available on your operating system.

Disconnect all cables and power supply from your computer. Press the power button and hold it in to release all energy from the pc. Remove the side cover to all access to the inside of the pc.

Look for the card that has the video connection where you had your monitor connected. Remove the two outside screws on the metal bracket on the back which holds it in place.

Pull the video card out away from the pc towards you. Sometimes you need to wiggle it in order to get it out. Some cards have additional cords which connect other places. The majority that I have seen do not. If your card does, take a permanent marker in order to mark where they connected so that you can remember later.

Insert the new card in the same place where you removed the old one. Put the two screws back in the rear metal plate to keep it in place.

Put the side panel back on. Reconnect all cables and boot it up.

Video monitor says there is no input and to check the cable connections. connections and cable are good. Does that mean the video card has probably gone kaput?

It may mean that the video card is bad , but not always the case. Start with borrowing a known good monitor from a working pc and then test the following ... video card, memory chips ect. Does it show screen ever or only goes away in the middle of boot up? try booting in safe mode F8 key if it happenes in the middle of boot up.

Green display on boot up Please help

Check to see that there are no machine BIOS settings that could affect the monitor. Normally, the bios controls display until the OS takes over. If your XP screen after bootup looks fine, I don't see how you have a problem with your monitor setup under Windows.

Clicking noises coming from monitor with hdmi cable attached to computer have no problems with other connections that came with monitor

Try getting a video card, if not look for a new monitor.

Reason i say get a video card your motherboard is probably working to hard depending on how old your pc is. When getting the video card it takes stress off the board when monitor is plugged into video card.

Tower will not boot or communicate with monitor

Don't throw out that computer or replace any components just yet.

After much trial-and-error, I finally figured out the solution for this common issue with certain HP Pavillion models. It turns out to be a design flaw with the front-panel memory card reader. Somehow the card reader's firmware gets scrambled, and it prevents the computer from booting. You can test this on your machine by temporarily disconnecting the card reader cable at the motherboard header. Voila - I'll bet you $1 that your computer will now boot!

The solution is buried deep inside this HP tech support document. The card reader firmware needs to be reset.

Here\'s how to fix it once and for all:

1) With the computer power unplugged (duh), open up the case & disconnect the card reader cable at the card reader itself - NOT the end that connects to the motherboard header. Make sure the cable end is not touching any metal components before proceeding to step 2 (another duh).

2) With the cable still disconnected, fire up the computer. The tech support doc says to let it boot into Windows and stay there for about 5 minutes.

3) Shut the computer down and reconnect the cable to the card reader.

4) Turn your computer back on - your memory card reader will work and, most importantly, the computer will no longer hang at POST!

I suspect that when you fire up the computer without the cable connected, the card reader is designed to reset its firmware by grounding out through the case - sort of like a CMOS Reset jumper on a motherboard.

I hope this solution is helpful to others.
