I supplied a Shuttle XPC to a client around 2 years ago, and a couple of weeks ago he brought it back, as it had taken an accidental fall off the back of its shelf. The fall could have been up to 18 inches, he is not exactly sure.
Anyway, now the PC shuts down after around an hour. It shows all the signs of being processor temperature related. Once it shuts down, it takes a while to get it going again, but when it does, it is fine for a while once more.
When you look at the logs from within the control panel, there is absolutely nothing, so I can rule out software or HDD issues.
I removed the processor heat sink, removed the processor and reseated it. I did notice that six of the processor pins were slightly bent, so I straightened them out and put some fresh themal paste on and put it all back together. Still no joy.
I also removed and reseated all of the other removable components (memory, graphics card, cables, etc). Still the same problem.
I am now suspecting that there is maybe some kind of hairline crack in the motherboard. I cannot see anything, but I cannot think of what else it could be.
I have spoken to Shuttle support, but as it is out of warranty, they have said it is a back to them job if they can help at all.
I want to exhaust all possible options before that, as I think it will be cheaper to get an Asus SFF unit at £70, than start messing around returning kit that is two years old.
Hope someone can help.
