My screen gets blue jagged lines, and computer freezes. I will need to restart computer, and then it happens again shortly after.

I ordered the computer from Alienware in November 2008, when I got it i was running dual 512MB NVIDIA GeForce 9800 GT.

This past spring one of cards started having this problem, so I took it out and have just been using one since. I ordered an identical card and when I recieved it- it had similiar problems (red lines instead of blue?) so I sent it back.

So, I've just been using my single card that I originally had for past few months.. and it is starting to have the same problems now! Why are these cards having such short lifespans, what should I buy so that my computer runs well again!

Other spec:

Processor: Intel® Core™ 2 Duo E8400 3.00GHz 6MB Cache 1333MHz FSB
Power Supply: Alienware® 750 Watt Multi-GPU Approved Power Supply
Memory: 4GB« Dual Channel DDR2 SDRAM at 800MHz - 2 x 2048MB
Motherboard: Alienware® Approved NVIDIA® nForce 750i SLI Motherboard

Hi Avetra :D
When was the last time you cleaned the inside of the case out?
Try removing the gfx card, blowing out the slot and re-seating
the card securely then do the same with the RAM sticks.
If you are intent on purchasing a new gfx card can you provide
us with a budget so we can recommend the appropriate options, I
would however suggest that you check that another issue is not
damaging your gfx cards, heat or power instability for example.

Before today I had not cleaned it out well since July. I've blown into sockets, used compressed air, and wiped down the case pretty thoroughly.

I'd be willing to spend no more than $300 on gfx card, and am willing to if it means my computer would run again. I play a lot of games, would be nice to run some of them with even higher performance than I did before.

I'm not sure how to check to see what else could be damaging my cards, and am paranoid that there is something.

Heat trapping dust and an unstable psu are the 2 most likely culprits a lot of the time.
See how it goes now that you have had a good clean out and if it happens again have a
look for driver updates for your video card, below is a video card for you to look at;

Keep us posted on any progress and best of luck.
