Help Please

I set my ram frequency too high, now pc makes it past post, no lights on post checks but it’s a black screen. I pulled CMOS Battery for 5 minutes and I held power button for 10 seconds during all while the power cord was unplugged. It’s a cyber power pc prebuilt with a Ryzen 7600 cpu and a Radeon 7600 gpu. ASUS Motherboard but not sure which model. Cant get into BIOS to change XMP profile and all I see online is to reset CMOS. Please help.

The first thing I would do, is turn it on and wait for 15-20mins. As it's entirely possible that it's training the memory. I mean, the ram failed the set frequency and you reset the cmos. If it did not work, the next thing is to try another cables(hdmi/dp) or ports, and try directly connecting to the motherboard. It's possible that, when you reset the bios, display went back to the igpu.

If it did not work, just to skip troubleshooting the display, I would remove the gpu, directly connect the display to the motherboard. Proceed to remove ram and cmos(again), then reseat only one ram stick at each slot, until it boots. If it boots, then reseat the other ram and if it boths again, install the gpu. However, if it did not boot, reseat the cpu. I personally encounter in the past when I was optimizing my ram, that it won't even until I reseat the cpu. There was even a time, when I had to use a different cpu first and then put back my cpu, before it would boot again. Though it wasn't with am5, still you might want to try it.
