Trying to pinpoint a cause of freezing/crashing/BSOD w/ my girlfriend's PC. It is a large "iBuyPower" $1200 plastic hunk of gamer nerd shit that looks like it was designed by a 12 year old, running Windows 10. These crashes seem entirely random. It's not overheating, the memory/HD are fine (ran chkdisk and the RAM scan thing), there's no malware, and I removed virtually every stupid fucking helper/startup program that could be causing issues. Drivers are up to date. I pored through some of the advanced Windows settings, like the ridiculously long Power Management checklist and tried different settings, etc. - didn't fix the issue. We've used multiple graphics cards, so that can be ruled out too. It's been formatted once already. Event log tells me next to nothing. One BSOD was "kernel security check failure", another one mentioned the "usbport.sys" file. I just tried unplugging the USB wifi dongle and updating the motherboard drivers, so I'll see if that changes anything. Any ideas here? Apparently this PC has been prone to crashing even when it was relatively new. My last resort plan (if formatting again doesn't work) is to gut the parts and rebuild it using a new motherboard.
