Messed Up Screen + Blue Screens

So ye this problem has been bugging me this for a while now, I tried everything but nothing has worked...

When I'm playing GW sometimes I get a lagg spike but it's not my internet it's just fine, it's my vid cart or something. I know this because sometimes in the after effects off the lagg my screen gets messed up for a couple of seconds and confuses graphics...for example the picture of the skill Freezing Gust is black or something. However sometimes it gets that badly that it sticks in to this freaky outta space static mozaic messed up screen and kills my visiabilty....and occasionaly it ends in a blue screen...

The blue screen says someting like: nvlddmkm.sys

I tried everything remove vid card drivers tried without drivers, completly removre drivers (used special program), reinstalled GW.

I NEED YOUR HELP

If my story wasn't really clear I'll add some screenshots






Thanks in advance

How hot is your system running?
Does your Tower have adequate airflow?
Is there a Mountain of filth in the tower?

Readings from SpeedFan:

GPU: 71C
System: 28C
CPU: 54C
AUX: 19C
HD0: 31C
Core0: 64C
Core1: 61C

I got a CoolerMaster CM 690 tower so I expect the airflow to be sufficient

Are those CPU/GPU temps under load, or idle? if it's idle, that's a little toasty.
-even a little toasty under load for my tastes.

system specs pls.... full specs that is

your core temps seem a little out of whack. hmmm..

off topic
when was the first screen taken ? ^^

Open the machine up and make sure any & all cooling fans are working. Blow out any dust bunnies, clean any air filters. Re-seating the video card may also help.

I'd reinstall drivers first and then retry, but those temps you posted are a bit on the hotter side. Like post above mine also check for dust clogging and make sure fans are actually running.

Ok I've cleaned my comp this morning as most of you said and I haven't got any problemys yet!

So I'm considering it fixed but not 100% I'll post when I am

So you cleaned dust out of it? If it stopped your problem I'd rule out everything else because it was highly likely your GPU was baking to death while tryin to pump out GW under heavy load. Do hope that is the end of the problem for you though, can't say the same for me...

FFS I just had it yesterday again xD so ye..... haven't tried other suggestions yet tho.

Btw, the problem I'm having is only with GW, with other games that are far more demanding are running as they should run....

I'll upload my dxdiag if necessary..

please do - need som system specs and also the temperatures to see if it's overheating in any way. GW is the most heat sensitive game I have played, I know it's not all that graphically challenging for the modern video card, but it will crash or glitch due to heat far before the "danger point" of the video card itself.

I recommend Everest Ultimate (free trial version download works well too) to monitor system temperatures.

The screen caps look like typical graphics RAM problems.
These problems can be the result of the video card not being fully seated in it's slot. You could try removing the card and re-inserting it - remove the 1 screw holding it in place, release the locking tab at the rear of the socket and pull the card straight up and out. While it's out check the card and socket for corrosion, dirt and/or damage, then re-install it. Make sure it is fully seated. (You can also simply wiggle the card up & down in the socket, if removing it is a problem.)
If that doesn't help, there is a good chance that the card has been damaged by overheating, or is just plain bad.
