When I switch computer on I sometimes get a no input signal on screen. I have tried a diffferent monitor and that sometimes works and sometimes doesn't. So the monitor is probably ok is this a graphics card problem. he computer loads up ok you can hear it loading.The computer is less than a year old and has been iffy on and off roughly every couple of months since I got it.

Hi and welcome to D-A-L

are the graphics on-board or a separate graphics card?

what make PC is it?

The computer is an Aries and it has an onboard graphics card but a separate card is being used as the onboard one is not good enough for the drawing packages that are constantly being used.

Thanks .

is the onboard graphics disabled in the BIOS?
