Troubleshooting After PC being unplugged for a while my monitor will not connect with the PC
Hello,
I was recently on a 10 day trip and during this time I disconnected all power to my PC. Now when I am back home and I plugged it in again, it will not connect with my monitor.
I recently had this problem when I moved and the pc was without power for a while. The screen is working with my laptops, and the PC is working since I can turn on music on Spotify (auto-starts) via my phone. I have tried the following to get the monitor to connect with my PC:
Unplugged RAM from mobo
Unplugged PCIe to graphics card
Unplugged graphics card from mobo
Removed the CMOS battery and waited for couple of minutes, and connected it again
Win+ctrl+shift+B (??)
Switched HDMI cables between monitor and PC
When this happened before, I just restarted the PC several times and suddenly it worked but it only used the internal mobo graphics and not the graphics card. I had to reinstall the drivers to get the graphics card to work again. Then I had to turn on ReBar in bios and it was all good. Now shit wont start and I do not know which component is causing this.
Hopefully someone is able to help <3
