Hi guys!
Thanks for this über-cool thread - I just saved at least over $400 on this neat little hack.

My Dell XPS m170 was suffering from blue, random pixel artifacts all over the screen both at boot and in Windows after running for a while. It would then completely hang and become non-responsive.
Dell boot diagnostics boot tool said the video memory chips were failing:
Error Code 5300:0119
Msg: Detected a failure while writing and reading video memory. Video mode: Fh (640x350x2). Address A0080h, expected to read 0h, but read 20202020h instead.
I then disassembled the laptop and discovered a LOT of dust, hair, etc. clogging between the fans and the coolers. I cleaned it, and reassembled the laptop, but it still had artifacts, etc.
I called Dell for support. Since the warranty had expired, they would charge me $415 for a refurbished replacement card - provided that I send back the old one and installed the new one myself.
So after reading this thread, I thought "what the heck - I have nothing to loose and $415 and a working laptop to win", so I went ahead and did it, with a bit of disbelief.
I "baked" the card at 200 deg C for 9 minuttes, took it out and let it rest for about an hour. Then I cleaned the cooling elements a bit, and applied fresh thermal grease to the nVidia chip.
Once again I reassemled the laptop and turned on power while holding my breath. It started up as normal! I quickly re-ran Dell diagnostics and no errors were now detected.
Next thing was to boot into Windows and install 3D Mark to stress test the laptop to see if I could provoke any hangs, etc. I did between 10-20 3D Marks runs, and all was okay!
I also ran FurMark, which is said to be the best stress tool for video cards, and goes far beyond what is considered "normal" use". I ran at maximum stress for about 20 minuttes, and the temperature did reach 104 deg C, but it didn't crash.
Think twice before you throw away that video card!
