Gateway sx2800-01 powers up, but no display or beep heard from the tower.

Usually there is a beep after I start it up, but now I get nothing. Nothing appears on the monitor, except for the gateway logo and then a "no signal" message.

I tried reseting the power, didn't work, disabled the graphics
Card, didn't work.

Can anyone help me, please?

Are you using the Intel Integrated Graphics controller or are you using a discrete graphics card?

The integrated controller, and I disable the chipset via the device manager in the control panel.

My job.

Something has failed during the POST (i.e. Power On Self Test).

Any tips on how I can pinpoint what is failing?

Has any component been changed or added recently?

Can you still get into the BIOS Setup utility menus?

 

[Stlbullet]

No, mornings been changed, and no I can't get into the BIOS .

Sorry my stupid iPod autocorrect said mornings, I meant to say that nothing has been changed.

Try removing all of the memory modules to determine if the system will generate any beep codes at all.

If you still don't get any beep codes then there is something wrong with the motherboard.
