Sudden Black & Green Lines
This happened twice today already, though there's like a 10 hour interval between the 1st and 2nd times of occurrence. It's just all of a sudden, regardless of what I was doing, the screen suddenly changes into a black and green vertically striped screen, and a constant electric buzz can be heard over the speakers. Both times I'm forced to do a reset because the system does not respond. The lines are really slim, unlike the ones you see on TV, and are alternating in color between black and green.
Please help me shed some light on what's wrong. My PC's just 2-3 weeks old!
I'm running an Intel i5 750 Quad-core processor with 4GB DDR3 RAM on a Genuine Windows 7 Home Premium 64-bit OS. Video card's a Gigabyte Radeon HD5770 1GB DDR5. I'm guessing it is either a RAM or Video card problem..
Hope you guys can enlighten me because if it's a particular piece of hardware, I'm still covered by warranty to exchange it.

Unless you have spares to take out and remove parts it could be difficult to know for sure. I would start by looking at GPU then motherboard. Make sure you have up to date 64bit drivers. I have not had this hapen to me but if I did then I would start looking there.
May be try a bare boot by removing all the components from the case and setting them up on a non conductive surface. Sometimes taking the whole thing apart and putting it back together can solve these things.
+1. To test that, use Memtest86+ (let it run for an hour or so to get a few passes in, if anything is red, something is wrong with RAM or somewhere between RAM and mobo), ntune or atitool (for whichever card you have), and I don't know of a software program that can test PSU, but you can get electronic testers for 10-20, depending on where you look.
the checks on RAM and GPU shows no problems as well....
Are you overclocking at all? If you are, you can get something called "Artifacts" if you do it too quickly and not test it fully...
Artifacts can give you a colourful light show...and blue screen errors....
As for the question 'how old is it?', it's pretty much a month old?
This seems silly, but did you check that all your cables are secure? Like, ensure that the monitor cable is secure to computer and secure to monitor. It may also be a case of PSU outputting power with fluctuation.
