I have a problem with my computer. Below is the description, My monitor works well with one workstation. But when I use the same monitor with a different workstation, the computer powers up, but nothing is visible. What could be the problem?
If nothing is being displayed, it could be anything.
Easiest thing (if completely blank/nothing):
If you have two (or more) video inputs, make sure you are using the correct one - Graphic cards usually override built in.
Next up, it could be motherboard or PSU failure.
For anything else, you really need to be more specific in the problem, however, I suggest you search here as there is bound to be many other questions that can help you.
If you are using Windows press F8 on startup. Select Start in VGA mode If that works, reset your display settings to a resolution supported by your Monitor.
