So i just connected a beeper to the Mainboard but it doesnt make any sound when starting the PC normally. It does make a sound when i for example remove the RAM. What does that tell me?

Checked that already a few hours ago but there was nothing wrong. This may be a stupid question, but since I did an Windows update before, it theoretically is possible that a microcode update from Microsoft killed my CPU, isn't it?

I just tried it outside of the case with only the Mainboard and CPU Cable connected, still nothing. Also changed the RAM, it still doesn't work. How do i have to proceed now? How can i tell if its the motherboard or the cpu or even both? I dont have an additional motherboard/cpu to test..

It was from be quiet, but non modular..

Hey, a few days ago I bought a new PSU (Corsair RMx750W) because 500W probably won't be enough for the 2080 i'm going to buy soon. I also bought a new PC case, so I had to install the mainboard into the new case. After installing everything the PC started normally and it was on for like 20-30 Minutes and then i restarted it to install some Windows Updates. The PC restarted itself but since then i haven't even been able to get in the BIOS, all I get is a black screen. All fans (including the CPU fan) are spinning, hard drives are on, the LEDs of my mainboard are on, but i get no image and on start up the CPU_LED and DRAM_LED ist on, but turns off after a few seconds (I don't know if it's been like that before). Since i sold my GPU i only tried with onboard graphics. Things i already tried: Change to old PSU -> Same results, no image Unplug everything except Mainboard + CPU Cable -> Same result BIOS + CMOS Reset -> Same result Checked if CPU fan is running and the Front Panel is connected properly Is it possible that the PSU fried my mainboard/CPU? and how can i test wether only one or both of the components are actually dead? If so do you think Corsair would pay for the damage if i could prove that it was not my fault? Could it be something different than a faulty PSU? My PC: ASUS Z170 PRO GAMING I7-6700K Corsair RMx750W Thanks in advance
