I just built a new computer and installed centos7 (RHEL based) and I also tried mint 17.3 (Ubuntu based). Installation goes without any problems. The operating system runs smooth and everything is quick for hours and then locks up. I can duplicate the problem by opening multiple instances of firefox, chrome, timeshift, vmware workstation, disks utility, etc and keep toggling my 3D desktop and eventually it freezes. I can't even ssh into it from another computer. If I don't try to duplicate the issue, i can be running firefox and 2 or 3 tabs and it freezes after hours of use.I always have the top command running in terminal when on this machine. The most recent freeze, the CPU percentage of the top 4 apps are 52, 37, 21 and 10%, with ram usage for them at 2.0, 0.8, 0.8 and 0.4% respectively. Each time it has crashed the top apps have been different but usage has been roughly the same. CPU temp sits between 42-47 C in a room with ambient temperature of 21-23 C (AMD said the temps were good). Nothing extreme.When it freezes, the system won't respond to Ctrl+Alt+F1, Ctrl+Alt+Backspace or Ctrl+Alt+Del. It also is not available via ssh from another computer on the network...doesn't even show up on the network when frozen. I hard reboot to get back in.What I have tried:Re-installing different versions of LinuxResetting Motherboard (has current bios version)Testing RAM with memtest86Testing and swapping power supplyDownloaded and installed proprietary nvidia driverLooked at this post for ideasAt this point I'm doing all my troubleshooting in mint 17.3 and watching output with:top  and  tail -f /var/log/{messages,kernel,dmesg,syslog}Is there anything else I can do at the kernel level to try and troubleshoot/track down the problem?Hardware:ASUS M5 A97 R2.0 MotherboardAMD FX 8320 8 core 3.5GHz cpuNvidia Geforce GT 7302x8GB of Kingston Hyperx 1866 DDR3 RAM250GB Samsung SSD 850 EVO1000Watt 80+Gold Powersupply (Not needed but have for expansion ability...current system wattage ~280w and EVGA support said using high watt PS with low wattage system is inefficient but isn't issue.)
Troubleshooting new linux system keeps freezing

According to top, it's been 2days, 1hr and 46min since the last change (I made change, rebooted and launched top command). Its been running everything from virtualbox (installing and running Linux guest) to vmware workstation (running windows and Linux mint guest and installing more Linux guest), timeshift, multiple browsers (chrome, firefox with many tabs), toggling 3d cube desktop, running steam, etc and the system hasn't frozen. CPU has reached over 200% (it's an 8 core  so it can see 800%) with some of the multitasking I've been doing. The last change was removing the ubuntu nvidia drivers for the graphics card and installing the proprietary drivers directly from the nvidia site using their instructions. I did this as a last ditch effort before my original post, not expecting it to work given the number of threads i read that said the open source drivers worked great for this and similar cards. It looks like this time it was the graphics drivers.
