I need some help troubleshooting a potential RAM issue. My computer shut down suddenly after running for about 5 minutes, which was its first start-up since I moved. When I powered it back on, the system booted, but my screen, keyboard, and mouse wouldn't respond. I noticed the DRAM light was yellow, and after some research, I swapped the RAM sticks around, which seemed to help. However, when I try to use the third RAM slot (counting from the left), the issue recurs. Right now, I'm using slots 1, 2, and 4, leaving slot 3 empty. Is that slot damaged, and is it okay for my computer to run this way? I hope to do some gaming during Christmas. I have some technical skills, but this is the first time I've opened up a computer. Any advice would be greatly appreciated!

It's generally more stable to use either two RAM sticks in slots 1 and 3 or 2 and 4, depending on your motherboard. If you recently added RAM, try removing the stick you just installed and see if that helps. Make sure the remaining RAM sticks are seated correctly, too.
Have you checked the Event Viewer for any error logs? You can find it in the Windows logs under the System section. It might give you more insight into what caused the shutdown. Sometimes, a searchable error code can provide useful details!
Most motherboards use slots A2 and B2 for dual-channel RAM, which is the best setup for performance. I recommend placing one RAM stick in slot A2 and testing each one to see which one works best. When using two sticks, make sure they’re in the correct slots to avoid performance issues. It’s best to avoid having just three sticks installed because that can cause your system to revert to single-channel mode, which is slower. If you need any extra clarification, just ask!
Does the third slot fail regardless of which RAM stick you insert? If your computer recognizes all three sticks but still won’t boot with one in that slot, it might indicate that the slot itself is malfunctioning. This could be due to a bad connection or physical damage, as the error means your system isn’t completing the power-on self-test (POST) properly. You might want to consider motherboard issues if that's the case.
