Your video cards is the issue. To be sure, if you have another video with the same connector (PCI, AGP, or PCI-E Slot) try a different card. If they are ok, then you know. If not, then I'll would look for a port tester for that graphics slot. I've seen Port tester for PCI. I'm not sure about the others. Can't hurt to look.

Let me know

Desktop runs but won't boot


Normally if the hard drive is bad you will get some type of message on the screen.

If it sounds like it is running but the screen is blank, then try another monitor. Maybe the monitor is bad. Try another monitor. Borrow a monitor from a neighbor, friend, relative or co-worker and put it on the computer. If the borrowed monitor works, then your old monitor is bad. If the borrowed monitor does the same thing, then your video card is bad.

If it does not seem like it booted up all the way 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?

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

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.

My dell optiplex gx 260 has a blank screen when I turn it on. The windows xp professional screen comes up then when it goes to where the desktop should show up all I get is a gray screen


1. From reading your issue it seems the video card is defective.
2. If you have received the Windows XP splash screen and then the monitor displays a gray screen then only two things have happened here your drivers are corrupt for the video card or the video card itself has failed.
3. Suggestion: install a new video card compatible with Windows XP.
4. Most Dell Optiplex desktops have the video graphics card integrated to the the mother board.

Today while a user was trying to get online using IE, the machine froze and the monitor went blank. The monitor had red lines appear about 1/2 inch apart and froze. The machien qwould not soft boot. I did...


Your startup got corrupted. If you have an emergency boot floppy, you should be able to get to DOS. This may not work unless Floppy is in your Boot order. If your lucky, you have a cd/dvd in the boot order. Try to put your original XP or Vista disks in and see if you can boot. You can then see files.

Screen goes black. the power light is on, but the picture goes out. if i turn the power off, then on again it comes back for about 5 seconds, then goes black again.


Check to see if this problem follows in safe mode. Reboot and when the Dell splash screen comes up tap F8 until you see the multiboot options. Scroll to "safe Mode with Networking" let the machine boot up and see if you have a screen. If you do, right click on the desktop and set the resolution to 800 X600 and reboot normally. Usually when a screen goes blank in normal mode but shows up in safe mode means you have an incompatible resolution for the monitor or graphics adapter. This may be a driver issue or hardware. If the screen boots up in normal mode at the lower resolution, then try and go to properties again and bump the resolution up a bit, if it blanks again, try to go online and update the driver for the graphics chip.

Monitor displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

Monitor shows a image uo until sign on screen then goes blank


Does it go blank before you signon, or when you sign on? If before boot to SAFE MODE and check the video display settings.. you man have settings your monitor can't understand.
If that doesn't work and you get to input your signon and then it goes blank you most likly have a virus or malware.
Log into safe mode, and use SYSTEM RESTORE to a time before you stated having the problem.
Start - All Programs - Accessories - System Tools - System Restore

MONITOR GOES BLANK


Did you recently change or install a program that would affect the resolution and card output? Try booting into safe mode by holding the "shift" key during boot. From there right-click on the desktop and hit 'properties'-> 'display properties' -> 'settings' , check your resolution and drop it to 800x600 and then reboot. If everything goes back in normally make sure you have the right windows drivers for your video card. You can also check the driver version and settings while you're in safe mode. Sometimes the windows update drivers can act screwy and I would recommend getting them directly from your card manufacturer.
