I recently been experiencing some weird stuff with my pc.
it started a day ago I was playing some arma 2 and my frames droped from 60 to 1-5 and my fans in my pc were at 100% all of them even my hd7970 I turn off my computer and left it till today.
I turn it on to see whats causing the problem first I though I had a bad power supply or something because it was way too hot. I open my videocard OC software to check the temp and it was rising FAST, I also opened intel xtream utility to check the cpu temp etc and turns out the CPU its HOT and its using up all 4 cores and its at 100%... I do Ctrl + alt to check what program/s is using all my cpu power... and as soon as I click taskmanager the cpu usages on intel extreme utility goes back down from 100% to 10% and below and no longer all 4 cores are been used.
ok now I was scratching my head... because I cant find any program on taskmanager thats using that much cpu, so I close taskmanager thinking the issue is gone but as soon as I close taskmanager the CPU goes back to 100% and all 4 cores are been use and all fans are at 100% to cope with my cpu running at 100% .
I repeat this a couple times, close taskmanager cpu goes to 100% open it and goes back to normal...
