When the CPU is tested, the computer does not shut down. I wonder if it's normal for the GPU to have no overhead or over temperature prevention.
Apparently I was able to solve the shutdown problem. I was able to upgrade the motherboard BIOS from MB40II-4 (ECS) to Q2432M (Gigabyte). The notebook is no longer turning off for no reason.
But on the diagnostic tool, I'm experiencing error when running visParticle.exe, and it's not just this notebook that has the same problem.
The visParticle.exe did not work correctly on I5 2410M (Southbridge: Intel HM65 rev. 05) and I7 2620M (Southbridge: Intel HM65 rev B2). Does visParticle.exe not compatible with this family? Perhaps it has been rewritten to support the new families and the old ones no longer work?
I bought a new I5 2410M processor, and this one also presented the same error. In other words, it can only be incompatible software.
