Ok, so my current computer which I built around a year ago is starting to act funny. There seems to be a bunch of software and hardware problems which may or not be related. I'll start with the software. Sometimes I get messages that say that the antivirus (Security Essentials) service has been stopped, or sometimes its that adblock has crashed in chrome. I think that these messages have started happening after a friend of mine installed some kind of crap on my computer. It has been a year, so I think its time for a re install of Windows, but any other suggestions would also be helpful. Now for the (sorta) hardware problems. My computer has been crashing/freezing/blue screening a lot lately. It is intermittent. For example, this Monday my computer was derping every 10 minutes all day, but it has been running pretty well ever since. It ranged from blue screening (most of the messages were something along the lines of "Secondary processor clock interrupt not received", but there was one that said " A device attempting to corrupt the system has been caught. The faulty driver currently on the kernel stack must be replaced") to randomly rebooting to just plain stopping. And now for the most concerning of the problems, CPU heat. 9 months ago, I was comfortably running a 4.5 Ghz overclock on my i5 3570K with this cooler on this motherboard. With all 4 cores at 100% load I was getting about 70C. Now when I reduced the overclock to the stock 3.9 Ghz, I peaked at about 83C before I shut hyperpi (what I use to test it) down. I can't even afk overnight without worrying about it getting to hot. I suppose clearing out the dust could help, but I did that 4 months ago when it was still working fine and its not to bad right now. I might try re seating the cooler, but any other suggestions would be awesome.
