Recently after starting my computer I will get a blank screen on my Dell S2440L monitor and it would say it was in sleep mode with no signal input coming from the computer. The computer boots up with ligt on, no error signal beeps. I have checked the video VGA cable and even replaced it, I tried to reinsert the ram on the computer seeing if that was the problem and it still has the issue. Have tried to unplug the computer and monitor, no fix. I tried a different monitor, same problem.
Just wondering if the built in graphics on the computer is at fault and if a new video graphics card might be the answer? If I get a new card installed do I need to disable the built in one on this computer and how can I do this prior to installation if I cannot get to view anything on the monitor? Thanks for any help.
It could be the onboard graphics has failed. To verify, try to enter the BIOS screen at startup. On the newer HP model - start tapping Esc immendiately after pressing the physical start button. If the BIOS shows, then it is a driver issue, most likely. If no go, then perhaps an inexpensive graphics card can be installed.
The SUPPORT PAGE indicates a VGA and DVI output port. Have you tried the DVI port?

Have not tried the DVI port, no cable to try it with plus the monitor only has VGA connection. If I get a new graphics card do I need to disable the built in one on the motherboard that came with this computer or will it recognize the new card and switch to it automatically? Thanks for the help.
