pc doesn't send out signal to monitor

MafiaTux · 08-06-2008, 01:45 AM

my recently built computer worked fine for about two days then I rebooted one day and the pc won't give a picture to the monitor. I know the monitor works and the I have tried replacing the graphics card twice and using onboard video, tried replacing CMOS battery I even tried new ram. The build is a 2.66 pentium 4 2gb ddr2 RAM 128mb 5200 nvidia geforce graphics card, SATA 120Gb harddrive, motherboard model is a mini-itx ibase mb899f-r.

Please help I have no idea what to do thanks

Does the machine give you any beep codes with the pc speaker on boot? Try removing all expect the necessary hardware (leaving processor, memory and graphics.) If the machine still doesn't boot, I guess you may have a bad motherboard or a bad power. Or maybe a broken BIOS chip (sounds unlikely

)

No, no beep codes just the regular single starting up beep

Have you tried changing the graphics card to another bus? And is the monitor cable OK? I don't have very good hardware knowledge so these are all advices I can give for now.

Check the pins on the cable coming out of the monitor. VGA connector pins tend to get bent and that can cause signal loss or at least a weird color mixture in the signal.

And/or try a different monitor.
