WIll bios still display without display card.

by honsheung / February 10, 2007 4:48 AM PST

Dear all,
my display card seems out of order.
I would like to verify.

If I unplug the display card from the motherbaord then boot computer. Will it still display the bios by pressing delete?

And if so, does it mean that my display card out of order if i plug in then reboot but finally said: enter power safe mode ?

Must have

These are needed for the monitor to have something to display, that port is a must have. You can disable current port and then use another video card in place of your current video port or card. This will help in t/s'ing the problem.

Try just waiting at least 10mins. and see what happens other than powering up, just wait.

Find what is your key sequence to enter bios upon booting up and see if it allows a display at all. If none and you can see the bios for a short period, you either got a bad display or bad video port. As suggested, try the monitor elsewhere to see if that's the case. Sometimes, the power supply just can't cut it and poops out as another cause of your problem. The whole system has exceeded or stressed your power supply(PSU) beyond it limits or it has failed anyways.

If you're satisfied that both video card and monitor work well by themselves elsewhere, then that leaves the system itself as a problem. More than likely the PSU, power supply is at fault. It has lost the voltage level it needs to keep the system up and running. Even though it maybe showing some LEDs or lights, that isn't *all* the power voltages present plus the watts to do so. Replace the PSU with one at or better wattage rating and continue. You can swap ram modules around or try alone(is applicable) or be sure all cabling is truly seated as well. If none of that works, the PSU is the next course of action. If that fails as well, you have a bad mtrbd., replace it. You can try removing(unplug) all HD and CD drives attached and see if the boot-up display remains lit during the process, it should falter but if it remains lit, suggests a bad PSU.
