Hello, after looking for an improved CPU for my system, I found one, bought it, and then installed it into my rig. Immediately upon its installation, I noticed a significant increase in its heat. At idle, it clocks in at anywhere between 40 to 55°C (which is rare for my setup which normally gets around the upper 20s). When gaming, the number goes up to the mid to upper 60s and even to the lower 70s (normally it's at about 50). Upon waking up the next morning, I found my computer stuck in a BSOD with the error message SYSTEM THREAD EXCEPTION NOT HANDLED and that lvrs64.sys had failed. I looked it up and this is a file that is related to logitech webcams, something that I myself have. So, after looking around on the internet, I learnt that I should uninstall and reinstall the software (in the proper manner). I did this; but, nothing came of it result wise. I haven't had a BSOD since; but, I know that the abnormal heat of my CPU still being present indicates that something is very likely still wrong with my setup.
Here are my specs for the computer:
OS: Windows 10 64-bit, originally Windows 7 64-bit. Neither came with the system by default
CPU: AMD FX- 8350
RAM: 16GB DDR3 (2 x 8)
Motherboard: ASRock 990FX Extreme9
GPU: GeForce GTX 760 (EVGA)
SSD: Samsung SSD 840 EVO
HDD: Seagate
PSU: Rosewill HIVE Series Hive-750 750W
I originally built the computer in late 2013.

I have cleaned off the old thermal paste from my liquid cooler and replaced it with a new layer. I haven't updated the bios, though, as I'm having trouble finding the update for it. The ASRock website has a BIOS update page, but I can't tell which one applies to my motherboard specifically. Checking out the page with my motherboard and scrolling down to the tab saying bios lists an update that came out in April 2016, a month after my current version was released. Lastly, I have never tried to overclock any of my CPUs, including this one. I originally had a 9370, then had a 4350, and now have the 8350.
Thank you very much!

Do you think the BSOD's have been resolved by fixing the driver issue? If so, I may request that this be moved to the hardware forum for more expert advise on the other possible issues. If you are dealing with temperature issues then the best things you can do is find ways to cool the system by adding fans, better CPU cooler, etc.
I found the following information that may be helpful
Concerning your question regarding the temperatures with your processor. The maximum temperature threshold is 62 Celsius which set for the internal die (core) temperature of the chip. The core temperatures have an equational offset to determine temperature which equalizes at about 45 Celsius thus giving you more accurate readings at peak temperatures. The hindrance in this is the sub ambient idle temperature readings you speak of.
The silicon and adhesives used in manufacturing these processors has a peak temperature rating of 97+ Celsius before any form of degradation will take place. The processor also has a thermal shut off safe guard in place that shuts the processor down at 90 Celsius.
The Cpu temperature is read form a sensor embedded within the socket of your motherboard causing about a 7-10 Celsius variance form the actual Cpu temperature, which may be what you are reading about on the net.
You can use an application called AMD overdrive, that will allow you to monitor your temperatures accurately.
As long as your core temperature has not exceeded the high side of the 60 degree mark for extended periods of time you should be ok. 62 degrees holds a generous safety net to begin with.
I hope I was able to answer your questions, If you have any more inquiries don't hesitate to contact us.

I don't know how to test whether the BSOD will show up again or not. It's only been a couple days so I can't be sure that the issue isn't still here. But, in the meantime, I think that the high temps are also a pressing issue; so, you should probably move this over there. The thing that doesn't make any sense to me about the temperatures is how one cpu did so well but the other one, even after having cleaned up the computer and replaced the paste, has severe trouble.

Okay. I would recommend that you run the following stress test and see if your computer is stable. It will also check your CPU and memory as well.
Stress Test Your CPU - Prime 95
https://www.tenforums.com/tutorials/16474-prime95-stress-test-your-cpu.html
- extract the contents of the zip file to a location of your choice
- double click on the executable file
- select "Just stress testing"
- select the "Blend" test. If you've already run MemTest overnight please run the "Small FFTs" test instead. (run all 3 if you find a problem and note how long it takes to error out with each)
- "Number of torture test threads to run" should equal the number of CPU's times 2 (if you're using hyperthreading).
The easiest way to figure this out is to go to Task Manager...Performance tab - and see the number of boxes under CPU Usage History
Then run the test for 6 to 24 hours - or until you get errors (whichever comes first).
Monitor the CPU temperature and DON'T let it exceed 85ºC. If it does, then you probably have a CPU cooling problem. This won't necessarily crash the system - but check the output in the test window for errors.
The Test selection box and the stress.txt file describes what components that the program stresses.

I ran the MemTest overnight. It came up with no errors (it took 16 hours to run). I ran the CPU tester for 6 hours and it reported back with no errors. My CPU temps stayeddead on at 67°C and never budged an inch.
What do these results mean?

The average temperature for that CPU (AMD Athlon FX 45°C - 60°C). IMO since it is stable and th stress tests doesnt exceed that temperature by much I dont think you have any issues to be concerned about. You can try turning up your fan speed a little if you want it to run a little cooler using AMD overdrive utility.
