So I've had this pc since 2017. The specs are. PSU: 600w corsair cx600m bronze
Motherboard: MSI Z97 gaming 5
CPU: Intel i5 4690k
Memory: 4 8gb sticks of HyperX FURY DDR3 ram
GPU: rx460 4gb
So yesterday when I turned my pc on it would shut down after a couple seconds and turn on again and repeat this process until I unpluged it. This all happens before the BIOS boots up. But I noticed my motherboard's temperature indicator show the error "E0". And after researching I found this issue was related to ram so I removed all my ram sticks and reinserted only one back into my motherboard. Now my pc doesn't shut down on its own but my monitor doesn't pick up any signal from my gpu or integrated graphics. And my keyboard won't light up but my mouse does. And now the error on my motherboard says "2B". I know it's a lot but I honestly don't know what to do. If anyone knows how to fix this issue I'd greately appreciate it. Thanks.
PD. I have a lot of issues with my pc so I didn't know on which section to post this. So I am posting it here since my initial error was ram related.
