New Cpu overheating

[danbuchanan]

I recently got a Intel Celeron D 3.46 and a new motherboard to go along with it. I have started it up about 5 times and each start up puts me around 40C with isnt too bad but in 25 seconds or so it rises to 85C or so then the system freezes. I have tried cleaning the cpu and reapplying thermal paste and all the fans have been cleaned. Any ideas really stumpped.

your thermal circuits are perhaps not working. Take it to a shop for a motherboard replacement. You will need to reinstall windows. Save all your important files to an external device.
