Hi all

I took my 5850 apart in order to replace the TIM and clean out the heatsink and oil the bearings.

However upon booting all seemed fine until I launched MW3. It got so far as launching the level and then BSOD.

Reboots failed

I left it off for a while and booted up to windows fine. I downloaded and launched bitminter Java client and as soon as it started to mine, BSOD.

When I was removing the old TIM some lodged on the processor between two transistors (?). See the image attached. The transistors are the ones on the bottom left of the heat spreader. Note the image Here is not mine its one I found online

The only other thing is that if you see the top left of the circuit board there is possibly a vrm. On the heat spreader side the Tim had crumbled. Anyone know if this is definitely a vrm requiring Tim?

Its antec formula 6 nano diamond. It says thermal conductive (obviously) but nothing else. Though the whole thing should have done nothing if it shorted

The pad completely crumbled and I didn't replace it so that might be it. As its a problem that happens after a while it feels like a heat problem
