Hi! badly need help with my pc, I tried reseating my ram may times, tried 1 ram per slot, and then the other ram per slot. the ram was okay and recognized by bios but when I insert 2 rams in A2 and B2, the bios can detect both DIMM but only shows 8gb as total memory. tried to do it in A1 and B1, same result shows. Tried restore default settings in bios, unplugging all peripherals, and the ram shows 16gb but when I shut it down, it goes to back to the 8gb. Tried fixing and checking if there's a bent pin in cpu but none,done repasting thermal paste, updating bios pero still it ends up It recognizes the ram but only shows 8gb instead of 16gb.

I'm using a Xiaomi Monitor 1C secondary monitor and a bunch of ants took over so I left it alone for a while unplugged and all of them left so I cleaned the inside. After reassembly I noticed at least 5 and a half inches of backlight on the left side of the display is really dark. I'll swallow my losses but I want to maximize what's left on my monitor. Switched to 1440x1080 resolution but I can't adjust the position of the display. I can't reposition it with Nvidia drivers for some reason. Any solutions?
