Here is my system specs. Graphics card - Radeon RX550. Power Supply - 850 Watt. Motherboard - ASROCK B450M Pro4 AMD Promontory B450 Sata 6Gb/S. Memory - Corsair LPX 16Gb DDR4 Dram 3000 Mhz. Are these not compatible parts? Every day at random intervals the system will hang and black screen. I do not use this for gaming. I CANNOT EVEN READ MY EMAIL WITHOUT A CRASH. It happens multiple times a day. No I does not matter what I am doing. ..... Using Word - Outlook - surfing the net Etc. I have updated everything. I allowed the "AUTO UPDATER" to do it's thing and still I have a problem. Is it just AMD?
