  • twandre Feb 11, 2009

    It's just the same

  • twandre Feb 11, 2009

    Still no change, it try's to boot, turns off, try's to boot, then all three fans screams into overdrive. That's all it does.

  • twandre Feb 12, 2009

Hi there
plug the monitor into the on-board video, if the machine boots up go into the bios and disable on-board VGA, save settings and turn off the PC then install the video card again to see if it worked.

Good luck and thanks for using Fixya!!!

    ok try clearing the cmos, you should find a bit of plastic next to or near the motherboard battery, like this >>
    make sure the power coed is removed when you do this

    good luck

    do you get anything on screen?

  • Lee Hodgson
    Lee Hodgson Feb 12, 2009

    Ok, take the memory out and turn the machine on, if it beeps, count how many there are and if they are long or short, if don't get any beeps at all, it could only be the processor or the motherboard itself.
    Post back please

My dell gx260 ligth come green if i turn it on but for a few mins time it turn orange why


Do you mean the monitor's power light starts green and then turns orange when you turn it on? Most monitors will go to a power saving mode when they do not get a signal from the computer.

The Dell GX260 has a green power light when on. When the computer is off, the light is off. If it is green and blinking, then the computer is in a power saving mode.

Diagnosis: start with the obvious: is the monitor cable plugged into both the computer and the monitor (if not permanently connected to the monitor)? Are you connected to the active port? (You can add a video graphics card in most desktops. The motherboard video port usually needs to be disabled to use the card ports. If you plug in the monitor cable to the disabled port, it won't work.) Is the monitor set to the correct input? (This applies if the monitor has several ports. In that case, there will be a Source or Input button on the monitor.) Is the computer on? The GX260 has the power button on the front. (Other computers have the power button on the top.) There is also the power supply switch on the back which needs to be on.

Next try a different data cable between the monitor and the computer (if you can). Try a different monitor. If a second monitor works, than the monitor has a damaged main board. If the second monitor doesn't work, then the video graphics adapter has probably failed. Replace the add-on card, if in use, then boot in the safe mode to remove the old graphics driver. Then install the correct driver for the graphics adapter.

Note: the computer and the monitor should both be off when you connect the cables. Then turn on the monitor first and set it to the correct source before turning on the computer.)

I hope this helps.

E-machine t6212 won't boot. I actually have two e-machines that are not sending a signal to the monitor. One is a t6212. It is booting up because I can shut it down using the windows key + up arrow +...


If you get only one BEEP at boot then the computer is working..

Do you have a 2nd monitor to test with?

if it BEEPS more then once...
pull out your mem chips and test,,
If itt works them one of the mem chips are bad if not..
pull out all pci cards and test.. if it works its a bad card...
if not unplug all HD and CD roms and test.......

If not fixed yet it maybe a onboard video problem...

But IF you put a video card in b4 the problem started then your bios may have auto set it sellf to PCI/AGP mode.

Check bios setings,, look for onbord setings for the video

I have a HP dc7600 SFF. Tried to Install 2 graphics cards no vid


The dc7600 SFF only comes equipped with a 240 watt power supply. I think this may be causing your problems.

I am currently looking for a graphics card for the same comp with the HIS ATI HD 4350 in mind, but the website states that a 300 watt power supply is recommended.

XFX 8600 gt not displaying on bootup


can't say for sure but I would believe it would have to be with your power supply, you might not be getting enough power out to run the card. Try putting in a different power supply and see if that works.

I have quite a few d530-SFF systems. They have the ''standard PCI'' slot ''carrier'' that plugs into 1 of the 3 PCI slots on the M/B and has 2 full-size PCI slots. I installed a PNY Nvidia GeForce 8400GS...


I checked the specs on the video card thinking it must be PCI-e and not old style PCI but in fact there is an old style PCI meant for just what you are trying to do. The problem is the memory at 512meg plus the GPU put your power requirements at 300w and I bet you have at best 185w in those units so they won't even start and you won't be able to cram the bigger power supply in there. Go with a card that has lower specs and 64 - 128 ram and you should be ok. Just check the power req. JC

Tecra M3 won't boot, hdd light comes on then off.


The hard disk can be installed in another computer, but it won't boot up and run unless the computer is the same make and model with the same devices as the previous computer.
If it is not then you need to do a fresh Windows install to get a working computer.
What you can do as an alternative is to install the hard drive in an USB hard drive adapter case and use it as an external USB hard drive.

Laptop won,t start up.


Possibility that the HD is toast. You can try to put a new HD in and reinstall the OS if you have the install disks. But the expense may not be worth it. $100 for a HD and another $120 for an OS. The one you have looks like its pretty old and it just might be time for a new laptop.
