[SOLVED] how can i fix this (red blue green lines)

Solution
Is this all new at once?
Has anything recently changed?

Green lines are usually caused by a monitor failure or by a gpu failure.
What are the rest of your specs?
Particularly motherboard, cpu, gpu and psu.

Start with checking hardware.
Can you test with a different monitor?
Or, can you use this monitor to test on a different pc?

Can you attach the monitor to a different graphics adapter?
I
Can you get into the bios screen? does it display normally?

Startup repair is entirely different and is unrelated to strange lines, more likely it is windows related.
