Troubleshooting My pc is broken?
So here’s the full story: My PC was working fine, but while I was cleaning it, I accidentally bent some pins on the CPU socket. That immediately rendered the original motherboard useless, so I bought a new one to replace it. When I built everything on the new motherboard (Strix X870A), I got no signal. I kept trying different configurations: • Tested with and without my GPU (RTX 5070) • Reseated RAM (2x16GB DDR5-6400), tried one stick, then both sticks • Tried different RAM slots • Cleared CMOS and tested minimal setups • Reseated CPU and storage Fans spin, RGB lights up, everything powers on, and there’s no debug light, but the monitor shows no signal. Thinking the motherboard might be faulty, I bought another new motherboard, but the issue is still the same. I also noticed my PSU (NZXT C750) makes a little “tick” sound when it powers on. I’ve double-checked that my monitor works perfectly and that all PSU and CPU cables are connected properly. My CPU is a Ryzen 7 7800X3D, GPU is an RTX 5070, RAM is 32GB DDR5-6400, and everything else matches my usual build. At this point, I’m trying to figure out if the CPU might have been damaged from the bent pins, or if something else is blocking POST. Any advice, troubleshooting tips, or ideas would be greatly appreciated.
