Graphics freaking out - horizontal lines

Specs: Win 7 Ultimate, Intel T9600 2.8 / 8 gig RAM
Hello,
This problem has been haunting me for a while now.
One day out of the blue I got small green horizontal lines on my monitor that are more dense and follow my cursor.
All of a sudden the issue went away for about a month or so.
Then one day I went to my PC to find the monitor "flashing" (I wish that I can post vid clips on here) and then after a hard boot the flashing went away and the lines were back.
An IT buddy of mine told me that it might be the power inverter for the display(this has a touch screen, but I don't use that option).
I love this AIO PC and hope that it is an issue that can be fixed.
Any ideas?
Thanks!

Try to use external monitor and see that whether it is good if yes then as your friend said inverter for the display is gone and you need to replace it.

Dashing,
Thanks for the reply. I was thinking of doing that, but this only has an S-Video out. I Guess I'll have to drag a TV down here.

Flashing could be caused by a bad inverter but the green lines are something different, a bad inverter would not cause lines. It would still be a good idea to swap out monitors to see if it's the monitor or not but I would not spend money on replacing the inverter if there are other issues with the monitor. Also, newer monitors don't use cold cathode florescent lights and therefore have no inverter, they use LED's for a back light. Make sure you know what you have before you start digging around inside

No, if the monitor itself is screwed up, I agree, the computer is junk.
For now, I'll see what happens with another monitor plugged in.
That flashing situation only happened once and cleared after a reboot and doing boot diagnostics and going back to an earlier restore date.

Post back with external monitor plugged in.
Did you recently have any upgrades?

No, no recent upgrades of anything. This has been going on for a while now.
I will try the s-vid out tomorrow while I'm off from from work. Thanks.

Eh, looks like there are no Vid outs to check this thing! Everything looks like they are inputs! Ugh...
