Re: getting no single to my moniter

Good start. Suggest you borrow a working monitor & hook it up to your pc. Still no video? Your Pc system has a built in video card. It is part of the mainboard. The video is run by a intergrated controller. Either the controller is defective or just the video is defective. You do have an extra PCI (white in color) slot. You can add a PCI video card, however it may or may not function with the defective video controller.
This link below shows what your mainboard supports. This is only a referance. Some other sites show differant configurations not consistant with this link.
2nd link. This is differant.:

Re: getting no single to my moniter

If your power light is on and no long beeps from your computer then is your intergrated video chip is bad. Your system board dosnt support agp or pci-e video cards. You will have to settle for a pci video card here is a good computer store to purchase one.

Whenver I turn the computer on, the moniter says that there is no signal. The vga input/output cords are in the desktop and the power cord is intact as well. Could you please tell me what may be the...

It is best to test your monitor on another computer. If it does not work on another then the Monitor is definitely the source of the problem. If your monitor works on another then the problem could be your video card or that your resolution is beyond the capability of your monitor. To test this, when you restart the computer if you do not see the BIOS screen or even the windows logo screen then it is the video card, but if you do and this problem occurs when you are in windows then your screen resolution is the problem. You could also try using a different monitor on your computer to check those settings.

I have an eMachine that the moniter will not turn on. I run a virus scan. But cannot get the moniter the stay on. the power light is on, the screen is not working.

The first thing we need to do is figure out if the problem is the computer or the monitor.

Have you got another computer around, a laptop will work too.

Moniter says no signal

You may need to replace the moniter cord or check the video card on the computer.

Computer would not boot up, only showed red light

I'd say power supply first.

If you have an expansion slot filled with a video card, remove the video card (provided you have onboard video connector as well) then try to reboot. I just went through similar issues with an GForce video card, it went bad, but the machine appeared to boot althugh I couldn't see the screen. Removed the card & it came up using minimal VGA drivers provide with WinXP.

Obviously you cannot check the video driver if you're not booting up...and seeing the screen.

Find a buddy with a regular monitor and hook it up and try to boot. Dell monitors sometimes require their propietary drivers, so write down the model when you take your pc to a friend's place, and DL the driver and install it (provided you got it to boot up)

the problem is the update you downloaded someone mixed with your graphic chip.. causeing it to only display dots and lines. the hp logo with the back round is the start up page. here are 2 ideas you might wanna try.

1. if your graphics car is in a AGP or PCI, pull it out and try useing the default card build in the computer.. if it is the default go out and bye a cheap graphics card and see if that works.. if not return it and get your money back.

2. try useing a diffrent moniter.. your moniter might of blown out. if that still dont fix it you might need to contact HP or the moniters manufactuer.

hope this helped!

Video screen comes on for a few seconds then is off again.

Try to see if you moniter is in the correct spot. I one time moved to a different house and when I put my computer together I pluged the moniter into the onboard video slot instead of my vid card slot and I couldt figure out for the longest time why it wouldnt work. Tech support couldnt help Sometimes its the easiet thing that makes the biggest problems.

If its not that then you may want to call tech support in your owners manual.

Maybe video adapter

(I'd like to stress that this is mostly speculative. Please don't read this as gospel or a guaranteed fix; it's just an idea or two.)

True, it may be the video adapter. But there are a number of different things that can cause a computer to not display anything during its boot, even though you can tell it's booting. The best thing to try first is (and only if you're comfortable digging in a computer) unplug all the peripherals in the machine (e.g. HDD, CD, etc.) and RAM and (if it's an add-on card) the video card and turn on the computer. Obviously, it won't boot properly, but as you slowly add components back in (one at a time) you might find the culprit.
Basically, a problem like this can be traced back to either a short/static build-up in some component or a failing/dead video adapter. If you're getting absolutely no display (which your description indicates) it's definitely a hardware issue of some sort.

Of course, it really helps to have a P.O.S.T. card handy to determine exactly what's going on and most computer shops you take a machine to will have one. Often, local shops will diagnose a problem for free or a nominal fee.

start system then hit the F8 key and then select "Safe Mode"...if you can successfully get to safe mode, then there is a problem with the screen resolution being too large (video memory or monitor limits)...then restart in standard mode..any change?

Moniter activation when turning on the cpu

RESETTING DRIVERS with new Video CARD- Start the computer in SAFE MODE (Hold Shift F5 when restarting PC) Go to Control Panel> System>Hardware>Devices - Remove the Old Card Driver (under Video) Press OK (and then Exit) Put the Driver disk in PC - Restart Normally Option 1 When your system reboots it will be in 640x480 16 color mode ignore any prompts. Run Setup from the CD/drivers disk Reboot Windows restarts with corrected drivers Set the Screen Resolution to your choice typically 1024x768 Option 2 When your system reboots it will be in 640x480 16 color mode When your are prompted for the drivers BROWSE the CD/drivers disk- (usually \drivers folder) Select your card from the Mfg list Press OK, OK Reboot Windows restarts with corrected drivers Set the Screen Resolution to your choice typically 1024x768 **Note - there is no shortcut you have to reboot when prompted, especially in safemode.
