Graphic problems.

I've had my PC about 3weeks, Everything has been working fine so far, for the last couple of days I've had graphical errors. When ever I view an image on a website it has green, red and blue dots random on it, if the webpage is built using images it's all over it, however if I open an image on my desktop all is fine.

Videos don't work as they should either, whether it's youtube or played through VLC, wmp etc the same happens but with horizontal blank jittery lines and shockwave flash crashes quite frequently, Videos played through a media player won't crash but will be unwatchable due to the dots flickering and the black lines.

Games have this weird flickering some objects will appear to disappear for a slight second them come back making objects look like they 'flicker', this happens more often in cut scenes then in actual game play, but still happens quite regularly, I also have a 'crackeling' sound in my headphones in all games, it's not constant but it's there and it's ONLY in games.

It all started during a session of swtor where I had some connection errors and CTD, as I looked for solutions online I started to notice these errors, Now games like FIFA 12 will CTD, GTA will have bad flickering same as sc2 but skyrim runs perfectly. I've also tried installing a fresh windows and the same problems occur.

My gfx card wasn't OC, I thought maybe a down tune would help the problems and if I try to even open ntune, the 2nd I do my PC will blue screen, my PC specs are:
i52500k 3,2ghz (oc to 4,2)
asus p67mobo
8gb corsair vengeance ram
gigabyte 550 ti gtx

I have no idea what to do, I think I've just got a faulty graphics card but wanted some advice before I sent it back, thank you taking the time to read my problem & any help is greatly appreciated.

Try updating video drivers for nVidia.

What make/model of power supply are you using?

550w OCZ, I'm not sure on the model as it's 3years old, I highly doubt it's a software issue adullahG and I've tried a fresh install and tried updating and downgrading my drivers. This randomly just started happening without changing any settings.

Sounds like a failing PSU. One of the symptoms of a failing PSU is distorted graphics as GPUs are very sensitive to power fluctuations. Heat and/or power are the usual culprits with these sorts of problems.

Try swapping another PSU, if available, to confirm.

Good luck!

Is there anyway I could lower power settings to confirm?

Drop the OC on your CPU back to stock. Same with you memory if OCed. See if it makes any difference. Also, how are your system temperatures at idle and under load?

CPU: 30/60
GPU 30/45

Temps seem fine, memory isn't oc'd and I dropped the oc on cpu already.

Fire up a game and see what happens (if you haven't already).

Same thing.

Do you have another PSU or GPU that you could swap to isolate the problem?

No, no I don't. Is there a way I could test or things I could do sway it one way or other? as I don't mind paying out for another PSU/GPU if they've failed I just don't want to waste money on a healthy part.

Borrow one from a friend/co-worker etc? Is that a possibility? What about another PC you have at home, etc?

Most of my friends have laptops and don't really use PC's for gaming. And I've got a couple laptops and a mac but nop no PCs.

But could a PSU really cause the dots on random images and video? As they look like artifacts, and my pc hasn't shut down on its own or anything like that, would there be a way to tell by looking at the voltages? I'm not very good with things like that though.

Poor power can definitely cause the issues you are seeing, as can a defective GPU. You have it narrowed down to the 2 most likely things. Now you just need to rule one of them out.
