I've NOT!!! got the Nvidia GeForce 7000m looping reboot problem
Acer Aspire 7520 laptop.
It's happened to me before, and it has righted itself somehow. It is said that the GFX processor overheats and becomes partly unsoldered due to a poor choice of solder alloy BGA in the original manufacture of the 7000m, and needs reballing or reflowing to fix the chip permanently to the m/b with new eutectic lead-free alloy.
I am not so sure of this explanation in my case, or how did the problem go away by itself? I have a feeling it is more to do with the following:
I am concerned that it is partly due to old thermal pads causing poor contact between the Heat sink and the chip surface. The reason I say this is that I can get the machine to boot and operate if I apply pressure to the GPU heatsink, despite everything getting rather hot. The temperatures appear to drop rapidly with applied pressure from values like 87 down to 73 degrees C in an instant. So tomorrow it is using a new thermal paste instead of the old thermal applied layer.
The temperatures hit the 80s, not the hundreds, way below the melting point of all but the coolest of solders.
I think what is happening is that the MCP (is this multi-chip-package or media-and-communications-processor?) -is simply overheating and cutting out, not just the graphics, but the other chipset functions too, due to poor thermal contact.
The initial manifestation was occasional freezing, noticeable on Ubuntu systems, and on 64-bit Windows 8, not other windows, at first. The thing is that it is Windows 8 x64 that seems to stress the chip more than W8 x86 or either x86 or x64 windows 7 versions. Once the problem gets going it affects everything of course. the freeze ups then happen at the bios if it gets that far, during chkdsk if windows manages to boot, or during a windows repair from USB or DVD. At worst, a reboot, power down, reboot cycle sets in, which is just horrible.
I wonder if a similar problem is affecting the other people with Laptops with their Nvidia MCPs, and frequent freeze-ups?
