I have a problem with my desktop pc.
As I turn the pc on, the lights are blinking,fans running, but monitor shows no signal.
But I can hear the windows welcome sound from the speaker.
I tried to change to different monitor, unplug and plug back the vga, hold down power button.
But it still showing no signal on the monitor.
Please tell me what to do.
Thanks in advance

Thank you

Try this 1

Try resetting your BIOS settings.

Turn off your PC and remove the power chord --> Open the cabinet --> Remove

the CMOS battery for 15-30 minutes and then put it back properly. Now plug the

power cord back in and switch ON your PC.

Click on the below hyperlink "CMOS Battery" if you don't have any idea about the

CMOS battery

CMOS Battery

If the problem still exist, click on the below link and follow the instructions in

"Hardware Reset".

Good Luck

Thank you
We have this exact problem...however...the computer and monitor work perfectly fine with each other everywhere we have tried them except the apartment where our son is currently staying. We have verified that the wiring is fine in the apartment and his roommate has no issues with his PC/monitor set up the same way. We have brought the PC and monitor to a few other places since and it always functions just fine. We go back to that apartment and the PC and monitor dont work together again. We are at a complete loss as to what is going on.
Thank you
