For a few days my computer has being having.. problems this happened after I left it running for a week without breaks, and decided to turn it off finally for a windows update next morning it decided to freeze while loading windows/in bios posting, obviously I thought it was the update that did it, but thinking to myself why would it freeze in the bios??, I thought about how I left it running the past week also. I decided to take it apart, and put it back together, cleared cmos, and it finally started up. Soon later was getting blue screens/instant shutdowns mainly playing games but not always games. Instant shutdowns lead me to thinking it was a overheating problem originally thinking it could be CPU but the CPU was never getting above 85c during gaming sessions.
 
Tonight after it shutdown on me mid-game, I managed to open the bios straight away and checked pc health and temperatures. Straight away I can see "NB - 101°c" "CPU - 54°c". NB which is North Bridge from what I've googled. I know for sure this shouldnt be at 101 Celsius, could this be causing blue-screens? for sure explains instant shutdowns. I'll be checking the NB heat sink soon let you know how it looks (if it has one idk) If theres anything else you think I should take a look at let me know, I need experience. Thanks
 
Thanks for this MB EVGA, I don't want to let go of it just yet though.

85c on the CPU is also hot as a mofo.

I've overcome my problems just over a week ago, I achieved this by changing my Hard Disk controller mode from IDE mode to AHCI mode, since doing this I have run into no problems. I honestly, have no idea why this has solved all of the issues I had, I thought it would fix 1 issue as my bios was freezing when it was I guess "Loading" my hard disks or detecting them not quite sure what part of the bios does this, but it loads for a moment and either froze or displayed all my disks and continued.
 
I also used the DISM command line to fix an issue which was making SFC unhappy, however I don't think this was causing my bios to freeze and even causing bluescreens.
 
Now that its working, I'm not ever sure how hot my NB is while in use, as I cannot seem to get a temperature to display for it in any software, but every now and then I've being checking the temperature, shutting the pc down quickly and checking it in the PC Health inside the bios which showed nothing near 100, (70-75c) at most.
 
Regardless even though its now working perfectly, I still need to reapply some thermal paste to the NB Heatsink and CPU, as its long overdue and will help my machine stay healthy.

70c~75 is still kinda hot for the NB even the cpu at 85 is toasty, are you using a fan on the NB heatsink? if not i would get one, 40mm if i remember correctly is the size

Lol my 40mm spun at like 4500rpm, it was a buzzy little thing,
