Look up CPUID or CPUZ and see what it reports. As the heat goes up the error does often show as related to memory because the CPU faulted on read or write.
This is dangerous for most users as such can cause a bad write to the HDD or SSD and poof, the user loses their system. Not a big deal as all I know (except for a lot of forum members) keep backups of what they can't lose.
As to 1 year, that's old enough to build up dust in heatsinks or compound to dry and crack or a corner of the heatsink to lift off. Time to fix it.
Basically speccy is showing that my cpu is running at 74 celsius idle, but at bios the temp was 40c, should I be worried? I don't think that I should re-apply the thermal compound since this is like a year old rig. I get BSODs but the error codes mostly imply something related to memory, so I doubt it is because of overheating. It has gotten louder for sure but seems like gpu fan's to blame. Would appreciate your help guys, thanks a lot.
