-note: Ive included the information for the Wireless device because I believe this problem is related to internet use somehow-

-The Problem-
Ive been having this problem for about a week now, since i started using wireless internet on my PC. Ill start up windows, fire up Guild Wars and start playing, after X period of time (this varies) the PC will freeze, then unfreeze for a few seconds, then freeze and then unfreeze again. If im quick enough to close Guild wars down, then the PC wont crash, If not, then it blackscreens and restarts without any BSOD.
Obviously I went through the motions to test the problem:

I ran Heavyload to test CPU and RAM stress - no problems, no crashes
I Ran Video Stability Stress Tester - no problems, no crashes
I Ran Memtest 86 for 3 passes - all were successful, no errors found.

So Im sat here wondering what the problem could be, i start playing again, nothing, no problems, the next day i go for some more gaming, and the crashes start again. This time i closed guild wars in time, and ran Everest to check the system tempratures, they are listed above at resting tempratures, i ran video card stress and heavyload simultaneously, the temps increased but didnt peak, and nothing crashed.
I noticed after shutting down GW, that the system tray in the bottom right had disconnected from the internet, i found that this happened everytime one of these "freezes" occured. I also noticed that the Audio devices were also afected by the freezes, the jack detection for the back of the PC failed, once GW was closed, everything returned to normal.

Im hooked on the idea that this has something to do with internet use, as if i turn of the net and play Hitman Blood money for a few hours, I have no problems. Also, the problem has only started occuring since I installed wireless devices.

Any help would be much appreciated.

Thanks

update
Disconnected wireless devices, ran 3dmark 2001

Freezes occured 2 minutes into the test
 
Disabled wirless utility
opened case, cleaned fan controller
replaced fan and heat sink

-adressed 87degrees heat issue, now running at 41degrees resting, 51 full load-

ran 3dmark2001, passed entire test without failiure

will now reinitialize wireless and test again in guild wars.
 
Pc now partially stable.

Discovered that whichever part of the mobo/CPU Fan is responsible for regulating the Fan speed is not functioning properly, and is causing the CPU to reach temps of 89degrees. Im guessing thats why the machine randomly crashes as there is no BSOD, it literally restarts immediately.
I use speedfan to monitor the fans. I played GW successfully last night for 4 hours without fault. Today i listened to music for 20 minutes before it crashed.
Is this still the Fan failing? or could there be another reason for a straight to black crash that I'm not seeing?

Help appreciated.
