Is this computer a custom build by any chance?
Those temperatures seem a bit high to me. On average, my CPU temperature is 30C (36C if I push it) and my motherboard temperature doesn't usually go over 25C (it's 18C right now). Your temperatures are about double what I would consider normal.
High temperatures can sometimes cause a computer to freeze and crash, which is certainly a possibility in your case. At the very least, you should open up your computer and clean it out as thoroughly as possible with a can of compressed air (and nothing else!). Possibly even apply a bit of thermal compound to help regulate the heat of your CPU somewhat. Leave your computer's side panel open for awhile and let it run...see if there's a difference in performance at all. Also, you should use PC Wizard to take a look at your fan speeds. There's a chance your fans aren't running at optimal capacity or perhaps you simply don't have enough airflow coming in (another reason why you need to clean out the computer with compressed air). Either way, there's a chance you might need a new/extra fan. But we'll wait before drawing that conclusion.
Because your problem doesn't occur in Safe Mode, it might be taking some of the stress off of your hardware by not having so many different things running. It could also mean you have a software issue. If cleaning out your computer and giving it some air doesn't help, then we might want to take a look at things from this perspective.
What protection (anti-virus, firewall, etc.) do you have installed on your computer?
Dr. Watson conflicts with certain anti-virus software and will sometimes create freezes and crashes. The severity level is usually a bit lower, but this is still a possibility. If you have no need for Dr. Watson, you might want to uninstall it via Add/Remove Programs. If you would prefer to simply disable it, refer to this page...

1.99.1 and
2.0.2, so download one of those. Once you have scanned with it, you can either copy and paste the log (this will take one or two posts) or you can save the file as a .txt and upload it as an attachment. By default, logs are saved in .log format, which currently isn't supported by our forum (I'm hoping to change this).
Go ahead and try out all of the above and post back with your results for everything. If you can't do one of these tasks, please let me know. And if you have any questions, feel free to ask.
