My Gateway GT5678 system powers up as if normal but no display and no error beeps. Fans are running lights on, no image. Checked all components on another computer and they work. Think it is the...
When you say you tested the other components, did you test the graphics card in particular on another computer?
If so, and if it worked, you can try clearing the CMOS. There should be an easily identifiable switch or set of pins with a jumper. With the power cable unplugged, set the switch or move the jumper into the clearing position, leave for about 30 seconds, then move it back into position (important! do *not* power on the system while the jumper or switch is in the reset/clear position). Try booting up the system again.
If it now has a picture, you will probably need to enter the BIOS and, at the least, make a basic change such as setting the first boot device (defaults to the cd/dvd-drive, then the primary-channel+master hard drive).
If you still have no picture, and you are using on-board graphics only, then there is a chance that the on-board graphics chip may have died.
To test this, you can put a graphics card into the system (I recommend a cheap, second hand one that you know is working, in case the motherboard ends up damaging the card), repeat the CMOS clearing process, and then try booting up the system with the monitor plugged into the graphics card.
If you get a picture, there's a good chance the on-board graphics have died. You'll want to go disable the chip to prevent it from causing any further problems by finding it under the 'integrated peripherals' section of your BIOS. If it's not located there, search for an option for the 'primary graphics adaptor', and change it from IGP to PCI-E. Then find any option for 'vga memory share size', and see if you can set that to 0mb. If it is the model with the 2400XT with its own 256mb memory, you'll need to find an option to disable it entirely.
Please post a followup if none of the above was able to help you, with clarification if possible as to what you're using and have tried, and I'll see if I can help further.
