I have an older PC with an Phenom II processor that we use as a kids' computer. It's been running fine until about a week ago when it randomly shut down and would not get past the Windows load screen before powering off again. The kids tried several times to boot it, and finally I got involved and tried a couple times before deciding that it must be the power supply. However, when I opened the case I found that the power supply was fine, but the CPU cooling fan mounting bracket had cracked and the heat sink was completely off of the processor.
I know that the processor is still functioning, because it is able to boot briefly (from our previous tests). I have a new bracket on order, and the fan still works. Now my question is this: How do I tell if the processor has been damaged? Once it's all back together, it may be obvious (serious errors, Windows crashing quickly, etc). But what if it's not? What if it's only one particular module, like an FPU, that may be used less frequently? Is there a way for me to test all the functions of the CPU to ensure that none are malfunctioning?
