For the past few days my PC has been hanging and crashing to the point that it's essentially unusable (I'm typing this on my laptop as a result). I can use it for a minute and then Windows locks up and usually whatever else I'm trying to use. The odd thing is that the hangs are not always system-wide. Sometimes a Windows program will lock up but I can use Chrome (until it also freezes). Or Chrome will go unresponsive but Task Manager will still work. The hangs last for a minute or two, then I usually get control back and things are responsive again. But it's back and forth the whole time, then it eventually crashes. As I was typing this, Windows crashed again and all I had was my background. I tried to ctrl+alt+dlt and it gave me an error that it couldn't bring up the menu. This last crash was after I attached the reports to this post, but I'm not sure I can even get them to work now..
I'm trying to troubleshoot the issue but I'm finding myself more and more overwhelmed by the day. I'm hoping that a bunch of people smarter than I am can get to the bottom of it. I've run virus/malware scans (Malwarebytes, Kaspersky) and found nothing. I've run chkdsk which corrected minor errors but did not affect the hangs or crashes. I've tried some programs to look at my SSD but they haven't pulled anything up really. A scan in HDTune showed no bad sectors. I've run Windows Memory Diagnostic, no errors. I tried booting up with only one stick of RAM (tried both separately in different spots). I've tried switching out my video card and unplugging extra HDDs.
I'm thinking it could be the PSU, but I don't know how to test it and don't recognize the symptoms. My CPU seems alright, but I could run Prime longer to be sure. I'm leaning towards my SSD or my HDD (Windows won't boot without my D drive, and I'm not sure why, as my OS is installed on my C drive, which is an SSD). I've tried swapping out the SATA cables and resetting the power cables, all to no avail.
I've attached the sysnative and perfmon reports. Hopefully someone can find something in there. Thanks.
