I recently upgraded my motherboard, processor, ram and psu.

  • Motherboard - Asus Prime B250-Pro - LGA1151 - 7th Generation MotherBoard (LGA1151, DDR4 Upto 64GB 2400MHz, Dual M.2, Intel Optane Ready)
  • RAM - ADATA Premier ADT DDR4 U-DIMM 2400 8GB RAM X 2
  • PSU - Corsair VS550 550-Watt Power Supply
  • Processor - Intel® Core™ i5-7400 CPU @ 3.00GHz × 4

System details looks like this -

The HDD remained the same after the migration.

Now, randomly and quite frequently, the screen goes weired and looks like this - enter image description here

After this, nothing works except a hard shutdown and reboot.

What could be going wrong? Any help would be much appreciated!

  • It looks like a graphic card issue, did you install any drivers? Can you go to tty when freeze happens? Try CTRL-ALT-F2,F3,F4. CTRL-ALT-F7 returns you back to graphical interface. – Mustafa Yılmaz Dec 06 '17 at 06:57
  • I haven't installed any new drivers yet after the hardware upgrade. I thought I'd be asked by the system to do it. Am I wrong? I can't go to tty when the freeze happens. Thanks. @MustafaYılmaz – Ashish Singh Dec 06 '17 at 07:05
  • You might need to install graphics driver, this image shows the onboard card. Do you have another graphics card? If so try to install its drivers. Basic google search helps a lot – Mustafa Yılmaz Dec 06 '17 at 07:12
  • Thanks. I don't have an additional graphics driver. Just checked the 'Additional Drivers' and there was an unknown device. Opted to use the 'intel-microcode' driver for the same. Lets see if it happens again. Any idea what that device might me? – Ashish Singh Dec 06 '17 at 08:05
