Hi guys! sorry in advance for the bad English.
For the past few days I have been having frequent crashes to a black screen (no BSoD), the pc stays on until I hold the power button to reset it, and there is a constant buzzing from the headphones/speakers. This usually happens after some gaming, mostly dota2. I tried cleaning the fans and checking the PSU pins to the GPU but everything seems in working order, I tried chaging PCI slots like in this post but it kept crashing so I changed it back. I then updated the bios, and did a clean install of my GPU drivers, but it still kept crashing. My CPU temperature never goes above 55ºC. I opened CPUID HWMonitor and got this readings, is this normal? I hear this tool is out of date, any other tool to double check?
