Hi again
NewfieEK,
Thanks very much for posting back your hardware specs from SPECCY,
AND letting us know you have a self-built or custom-built PC! Nice job on that. That helps tremendously!
Notice we had some of our
"Big Guns" jump in to help you (
Mike Hawthorne & kemical). Their thoughts on using various diagnostics to check your temps were on target and are invariably suggested to folks who built their own PCs.
Just about all experienced PC builders who fabricate their own PCs from parts use one or all of the above suggested diagnostics to monitor their CPU, Motherboard, GPU card, and Hard Drive temps and voltages, along with fan speeds. This is especially important if you are overclocking your CPU, RAM, or your GPU card!!
As you can see,
we've already uncovered a potential hardware fault with your system, and that is that extremely high temp of 97 deg. C on your CPU chip. 
Are you doing overclocking in your BIOS?
If so, if your PSU is undersized, that can contribute to excess heat on the CPU cores, which in turn can cause lots and lots of problems with your Motheboards and all other connected peripherals. 
Voltages that are low powering your various internal devices such as your GPU card and Hard Drive(s) can adversely affect their performance as mentioned above too.
The very next thing we need for you to do is to please check that PSU!!
We know that you've been inside your computer case before, since you assembled your own PC, so opening your case up and examining the side of your PSU for a lable with the specs and wattage shouldn't be to difficult for you. Often, as kemical astutely indicated,
the PSU label isn't facing where you can read it, and therefore you must disconnect the AC power cord from the back of the PSU if you haven't already done so, and remove the PSU entirely from the case in order to read the label on it for the needed specs. I've included a helpful YouTube video to assist you with this task here:
how to find your psu wattage in a pc video? - Bing video
The above video will be mostly a refresher for you, but clearly explains and shows you how to remove your PSU from your computer case and it's only about 5 min. long. Please find the Make/Model of that PSU and the Wattage shown on the lable, and post back here. We will attempt to do an analysis for you and tell you whether that PSU is adequate for your System hardware or not. We'll be able to do this quickly, so if I don't answer you right away, one of the other guys will jump in and tell you if ok or not. We all have built PCs for many many years and can do this quickly.
As in POST #10, kemical mentions using a CPU cooler, which can help with the temps some, but if you are overclocking your CPU or attempting to overclock your GPU card, this may be insufficient even with multiple case and Motherboard fans!!
Low voltage rails
(+/-12Vdc, +/-5Vdc) can wreak havoc with your CPU chip, GPU card, and the Motherboard itself including permanent damage.
After we get your PSU specs and do an analysis on your system, we may ask you to turn off all Overclocking for all devices in your PC. Then you will need to have downloaded the CPUID and
HWiNFO64 diagnostics that MikeH and kemical suggested and be running those after you disable your Overclocking, and we'll see if the Temps improve, and specifically they must drop below the 74 deg C mark. If they don't at that point, most likely this is from an Underpowered PSU, or even a faulty PSU.
If the CPU temp still exceeds the 74 deg C mark after the Overclocking has been disabled on all components, there is a good chance that it needs to be replaced with a larger Wattage unit (preferably Gold rated or better).
We'll await your PSU specs and can adise you further. But you can see where this is heading I believe.
Best,
BBJ

While the OP has got the case open to remove the PSU, he can look at the Motherboard itself around the CPU chip area and do a visual check for burn marks. If the OP built his PC, he could also REMOVE the Motherboard from the case and examine the bottom side or reverse side of the board underneath the CPU chip and do a visual check for burn marks or scorching there as well. <<<BBJ>>>
If so, did you install the rest of the components then yourself, such as the Motherboard, CPU chip, GPU card, RAM memory sticks, additional fans?
If you did not, and you purchased the computer already pre-built; this does not classify as a SELF-BUILT PC, but rather a CUSTOM-BUILT PC that you bought off the shelf from someone or at a computer shop, or you paid someone else to assemble the components for you to your specifications. Please clarify further!
