I installed a few days ago a new motherboard, CPU and RAM in my computer, practically building it anew. The operating system I installed is openSUSE.
After that my PC doesn't come back from suspend mode by using neither the keyboard or mouse. Furthermore 3 or four times after leaving my PC turned on all night, I found it in the morning completely frozen (mouse pointer frozen, time frozen 5 hours before the current time etc).
Furthermore, while working the PC froze completely out of the sudden for a minute and then it resumed working, but in the task manager's graph I saw the CPU cores jumping like crazy.
Moreover 3 times while working, out of the blue, the PC restarted and while booting it showed the following messages:
First I got this
[0.312256] mce: [Hardware Error]: Machine check events logged
[0.312312] mce: [Hardware Error]: CPU 5: Machine Check: 0 Bank 5: bea0000000000108
[0.312315] mce: [Hardware Error]: TSC 0 mce: ADDR 1ffff814f3510 mce: MISC d012000101000000
Then I got this:
[0.297216] mce: [Hardware Error]: Machine check events logged
[0.297253] mce: [Hardware Error]: CPU 4: Machine Check: 0 Bank 0: baa0000000060185
[0.297256] mce: [Hardware Error]: TSC 0 mce: MISC d012000101000000 mce: SYND 2d030000 mce: IPID b000000000 mce:

And after a few days I got this:
[0.333861] mce: [Hardware Error]: Machine check events logged
[0.333916] smpboot: #7
[0.341464] mce: [Hardware Error]: CPU 6: Machine Check: 0 Bank 5: bea0000000000108

[0.341474] mce: [Hardware Error]: PROCESSOR 2:800f11 TIME 1517065875 SOCKET 0 APIC 8 microcode 8001126
What is happening? I ask here not only because of the CPU graph but mainly because of all the CPU related hardware errors.
