I recently upgraded my processor to an i5 2500k and in doing so I had to upgrade my motherboard as well. I got a Biostar TP67B if that means anything to anybody....

My initial problem in switching over was I had no display on my monitor for some reason. The computer booted up fine and I could even hear windows loading up. So I slapped an old videocard in there just to see what the problem was and sure enough it worked fine. I was using the computer for about an hour until I got a SYSTEM_SERVICE_EXCEPTION bsod. My gut reaction was that it was a result my switching out the videocard, so I got the drivers for my OLD videocard (which is the one I was using at the time) and that still didn't work. So I'm toying around in the BIOS and I notice the CPU temp is like 78 degrees!

I removed the heatsink and inspected that and the processor to make sure I installed it correctly and let the whole system sit for a couple hours to cool down. I just tried it again and immediately upon start up (going straight into the bios), it still says it's around 80 degrees give or take a few. My question is.... would that have to be a bad sensor or something? For it to be THAT hot straight off the bat? If it's not necessarily a bad censor, how do I go about reducing that temp? Something seems genuinely wrong and I'm hesitant to go get a better heatsink/fan as I feel that would just mask some real problem.

Did u apply thermal paste correct?

Thanks for the reply. The heatsink that came stock with the processor had it preapplied so I doubt that's the problem. Also, my point is that even with improper heatsink/thermal paste/whatever installation, would it get THAT hot THAT quickly? I mean it's instantly up to like 75 - 80 degrees immediately upon startup.

Update: I did, however, notice that the fan is only running at like 1900 rpm. Is there a way to increase that?

You're reporting the temps in Celsius, right? Assuming the readings are correct & that you used the pre-applied thermal pad, you apparently didn't lock down the heatsink correctly. If you remove the heatsink for any reason, the thermal pad is shot & MUST be removed/replaced. Do NOT re-use a used thermal pad. Here's the thermal paste application instructions for your CPU:

Thanks for the reply. I stopped and got a new heatsink/fan on my way home today from work. I took off the old one and cleaned off the thermal paste. installed the new one with new thermal paste and everything and it still starts out at 60 degrees celsius and will climb all the way up to mid 70s pretty much on its own. Any idea what this could be?
