Sorry my bad english. I have blackscreen and bluescreen problem. I don`t play games. I watched youtube and horse racing, when blackscreen came out. I have tried drivers versions 19.12.2 and 19.12.3, but nothing help. All drivers are updated. Bluescreen error is IRQL_NOT_LESS_OR_EQUAL. All memory tests are ok (Memtest86 and Windows memory diagnostic). What is problem? Graphic drivers?
Thanks. I installed 19.9.2 in January. January was ok, but February isn`t. Blackscreen is gone, but bsod is problem now. Different bsod errors, everyday. ATTEMPTED_WRITE_TO_READONLY_MEMORY (moucclass.sys), KMODE_EXPECTION_NOT_HANDLED (tcpip.sys), IRQL_NOT_LESS_OR_EQUAL....
(Maybe) Solved. I set to manual these settings in BIOS. CPU frequency and voltage auto->manual, Frequency 3700MHZ->3400MHZ, CPU Voltage auto 1,45V->1,35V, Dram voltage auto 1,2V->1,35V and Dram frequency auto 2133Mhz->2400Mhz. No blackscreen, No Bluescreen, No freezes, nothing.
