First bios start I enabled EXPO
Once I got all new parts had some hiccups with installing drivers but once I got armory install it was able to install missing drivers. I notice when I open task manage or performance software the pc would random restart with no BSOD. I could run MH Wild for hours but random idle would restart, I then realize it having multiple programs running ie internet discord and then task manage or other things would then cause the crash. I made sure to check all default in bios and turn off EXPO since then pc works, but EXPO shouldn’t be the issue. I did look up QVL and the ram I got serial number isn’t listed CTCED532G6000HC30DC01 but there is a similar one listed on Asus site CTCED532G6000HC38ADC01 is the ram issue or something deeper? Again all parts are new and do not get overheated at any time average around 30-35c and during gaming hit 60c but only restarts while idle or just low loads like internet open. Psu shouldn’t be an issue said 750 is recommended and got a reliable psu brand rated at 850w
