What does it mean if horizontal green lines are all over screen?

Sometimes on google and other things text will be snowed out and i can't see it, this has just happened like 5 minutes ago, is it a dying monitor, PSU, or videocard?

Sounds like video card artifacting, which would indicate a faulty video card. If you have another card that you can use to test, I'd try that.

PSU? .. I don't know maybe the optical drive?

On a serious note, borrow a GPU from a friend or connect to another monitor or TV if you can to see where the problem is. I just had an LCD fail on me last week.

Either video card or monitor.

If its CRT it could be the monitor failing and you are seeing scan lines.

analog or digital connection? If analog, check if the connection is tight.

Could be either - try using the monitor with another computer.
