huge problem: tearing and flickering when playing games.!

Hey I have a serious problem

Long time ago I bought some good graphic card for my good new pc and then I started playing games
Well after playing for 1 month I started to see some tearing and some annoying flickering when playing games
(It was deffinatly not overheating and I did not need a new driver)
Well the more I played the worse it got till it started to happen everywhere, not only in games but on my desktop there were these little blue dots

So I bought a new graphic card called 8600 GTS BUT I quit playing games and only used it for internet and such but later on I wanted to play games so badly that I started playing games and this happened again.
(there is NOTHING wrong with any other parts of the pc, they are being upgraded everywhere in the middle of the story, I remember sometime getting a new powersupply, later getting 2 2GB sticks and later getting a new CPU but this graphic annoyance was still happening) And this just got worse and worse so lol I started to think that I let all my cards overheat so I bought a new one and I was not going to let it overheat.

So I now have an 8800 GT lol and I start playing games and this starts happening, (drives me mad, I just want to be ABLE to play games and I don't have this kind of money to buy constant graphic cards)

(I'm a little lazy to take screenshots and find a host for it and upload it and link it so I just googled pictures and found some that were exactly like mine)

(ok first you start seeing theese things, and some really annoying flickering, so some black stuff flickering all over the screen)

(then this comes

the more I play the worse it gets and this is exactly what I'm having
And since I'm so unlucky with this and I have not found any way to fix this I'm giving up on pc's when gaming, I want an Xbox or a playstation, I'm getting so damn tired of this. Spent money on 2 very good new graphic cards that didn't change anything so I just waisted a lot of money (O and I live in Iceland where everything costs a fortune and graphic cards cost almost twice as much and I'm not lying, and I must add in, I'm only 14 so it is kinda much for me to buy 2 graphic cards)

that last pic looks really ugly. please post the rest of your pc's specs along with os and nvidia driver versions. for general screen tearing you can usually fix that by just turning v-sync on. however, this looks more like artifacting which could be overheating, a bad card, or even a bad driver version. i remember a lot of people were having similar issues with bf2 and nvidia 6800gt's back in the day and a new driver fixed the issue. does this happen with all your games or just a few?

I would be willing to bet it's either a driver issue or heat. Have you tried leaving the side off your computer and see if it does it? When I get good and pissed off at driver issues, I just reinstall Windows and remove all doubt. Before the re-install, try using a program like driver cleaner (free) to make sure you have removed all remnant of previous driver then install latest driver from Nvidia. With your computer doing the same thing with so many cards it almost has to be one of these 2 issues. However it would be nice to know all your specs. CPU, Windows version, PSU wattage and brand, etc.

All that's left is either the motherboard has an issue, or it's overheating.
You say you live in Iceland, you don't have your PC sitting right on top of or next to a heater do you?

Ya thats the DS3L. What are your exact specs? Please list them because this would really help us help you.

Here's an example list:
P35 DS3L
2gb A DATA DDR2 800 RAM
Gigabyte HD3850 512mb
E8400 w/ Xigmatek s1283
Antec Earthwatts 500

Download CPU-Z and GPU-Z (google), CPU-Z will give you all the info you need for the CPU, the Mobo and Ram, GPU-Z will give you the info about the videocard.

By the way, check the 6-pin power cable is connected from your PSU to you videocard, when I saw the third picture I instantly thought of the card being underpowered.
