This is a thankyou aimed at Jago-Vs-Fulgore as ive had a similar issue with my GTX 280, my issue was a dry joint issue. When the card was stone cold it would crash on Win7 Aero Desktop, when the card warmed up it would load faultlessly!. I could do anything with it for as long as a wanted with perfect temps. Once it was warmed up. Tryed everything known to man to resolve the issue, even had a one on one talk with the GTX 280 lol. So after reading this forum and watching the video I decided to try it out myself. Stripped card down and cleaned up thermal paste/pad residue. Put pcb card on an upside down baking tray covered with tin foil, but instead of using foil balls to hold up GPU board (as I was a bit concerned to anything sticking to them) I used motherboard mounting screws, which were about 10mm long each, and poked the threaded ends through the holes in the PCB, so that no componants were being blocked, or touching anything. Warmed up my fan assisted oven to 195c or 383f (as my oven only does 5c or 41f increments) and put GPU PCB in there for 10 mins, lower shelf. After 10 mins, I opened up oven door, and gave the card 15 mins cooling time before I even took it out of the oven, then gently removed from oven, allowing a further 15 mins cooling time in ambient temps. By this time the card was stone cold, everything appeared to be fine! You can see the fresh solder flux floating on the top of some of the larger solder joints prooving that they had been heated up sufficiently. After re-assembling I powered up the card, I got POST screen! YAAAY, Green Light! YAAAY and a boot into Win7 PERFECTLY! I immediatley loaded GPU-z logger and kept an eye out on my temps, all good! idle at around 35c-40c and under load peaking at 77c-78c! Perfect. All 3d apps are working ok, no aero desktop crashing anymore, when loading up from stone cold, so far so good, just gonna keep heatcycling it over the next few days, to test reliability.
