...allowed on that motherboard. What model of Asrock mobo?
I've been using my PC without problems for two years. I'm running windows 10, I have an ASRock motherboard, and 2×4 GB DDR3 1600 RAM by Vulcan. I tried to install 2 more modules of the same model, and my PC no longer outputs to the monitor. It still boots up, with fans spinning and lights turning on, but there is absolutely nothing on the monitors. I haven't changed any settings in the BIOS.
I've tried:
- returning it to the original configuration
- multiple combinations of RAM modules
- booting with no RAM (it makes three beeps)
- checking connections on the motherboard
- booting to BIOS
- resetting the CMOS
- checking connections on the motherboard
No matter what I try, it's always the same result.
