I'm terribly sorry about the late response, I just got off work. So, I just recently did open up my case and clean it out with compressed air, all of the fans are running. 2 in the back, one on the side, and one on the front. The GPU, CPU, and PSU fans are all working. I've cleaned them all out not too long ago. I did open the case to make sure nothing was clogged up with dirt. I'm going to post a before and after screenshot of me gaming on ArmA 2.
A few minutes into ArmA 2 (where I believe it will crash soon):
Also, I've noticed something is odd about HWmonitor, it's missing stuff, or is it supposed to be like that?
Note: I am running EVGA Precision to make the fans run 100% speed, I do that when I game, all fans are turned up as high as possible.
She held for a few minutes longer, with rather terrible FPS on the games benchmarking (not like I expect any different), and then bam, instant shutdown, no warnings, no errors. The only way to start my pc back up is to turn off the psu from the back switch, unplug it, and then plug it back in a few seconds later, switch on, and power on. :/
Note: Not that I think this has anything to do with it. Everest Ultimate is saying that my GPU Clock is 738 MHz, original was 740 MHz. Also, I just noticed my video drivers were a little out of date, so I am updating. HOWEVER, as previously stated, I've reformatted twice since this occurrence, as it's been going on for a while now, I just haven't had the time to get it solved. In those past times, I know for sure the video drivers were up to date.
Okay, sorry for posting so much, you guys might be irritated. After the last crash HWMonitor picked up everything. So I am going to update the video drivers, get a screenshot of before, during, and after if feasible.
So, I did update drivers, and turned up my fans as usual (I have tried without the fans turned up), this time as soon as I started my game my computer shut down, however I did get a screenshot of HWmonitor before starting.
