After having verified that the video cable is installed correctly we should check to see that the computer's RAM is correctly fastened to the motherboard and functional.
The question states that the video card being installed is new, therefore we can comfortably assume that the card itself is not the issue. Other computer components that can cause a blank screen immediately upon powering on the workstation are:
- RAM
- Hard drive
- Bad video driver.
- Monitor input is faulty
however, assuming the installation was performed correctly, it is not likely to be caused by a bad video driver and a faulty monitor input is very improbable given that there are very few ways this can break to begin with.
A bad or missing hard drive may cause this kind of issue because the workstation will not have a windows file to boot. In most cases, this will not cause a completely blank screen without first allowing access to the BIOS.
After having verified that the video cable is installed correctly, the very next thing you should check is if the RAM is installed correctly. This is because the issue explained is exactly what will happen if a workstation attempts to boot without RAM, and also because it is the easiest fix among the possible causes and any troubleshooting should always be performed in order from the easiest fix to the most difficult.
